Mozilla Firefox is an open source web browser. XULRunner provides the XUL Runtime environment for Mozilla Firefox.

Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause Firefox to crash or, potentially, execute arbitrary code with the privileges of the user running Firefox. (CVE-2015-7201, CVE-2015-7205, CVE-2015-7210, CVE-2015-7212, CVE-2015-7213, CVE-2015-7222)

A flaw was found in the way Firefox handled content using the 'data:' and 'view-source:' URIs. An attacker could use this flaw to bypass the same-origin policy and read data from cross-site URLs and local files.
(CVE-2015-7214)

Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Andrei Vaida, Jesse Ruderman, Bob Clary, Looben Yang, Abhishek Arya, Ronald Crane, Gerald Squelart, and Tsubasa Iinuma as the original reporters of these issues.

The Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS) protocols. BIND includes a DNS server (named); a resolver library (routines for applications to use when interfacing with DNS); and tools for verifying that the DNS server is operating correctly.

A denial of service flaw was found in the way BIND processed certain records with malformed class attributes. A remote attacker could use this flaw to send a query to request a cached record with a malformed class attribute that would cause named functioning as an authoritative or recursive server to crash. (CVE-2015-8000)

Note: This issue affects authoritative servers as well as recursive servers, however authoritative servers are at limited risk if they perform authentication when making recursive queries to resolve addresses for servers listed in NS RRSETs.

Red Hat would like to thank ISC for reporting this issue.

All bind users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. After installing the update, the BIND daemon (named) will be restarted automatically.

Updated grub2 packages that fix one security issue and one bug are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

[Updated 27 January 2016] This advisory has been updated to document additional steps that need to be performed on BIOS-based systems after installing this update. No changes were made to the packages included in the advisory.

The grub2 packages provide version 2 of the Grand Unified Bootloader (GRUB), a highly configurable and customizable bootloader with modular architecture. The packages support a variety of kernel formats, file systems, computer architectures, and hardware devices.

A flaw was found in the way the grub2 handled backspace characters entered in username and password prompts. An attacker with access to the system console could use this flaw to bypass grub2 password protection and gain administrative access to the system.
(CVE-2015-8370)

This update also fixes the following bug :

* When upgrading from Red Hat Enterprise Linux 7.1 and earlier, a configured boot password was not correctly migrated to the newly introduced user.cfg configuration files. This could possibly prevent system administrators from changing grub2 configuration during system boot even if they provided the correct password. This update corrects the password migration script and the incorrectly generated user.cfg file. (BZ#1290089)

All grub2 users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. For this update to take effect on BIOS-based machines, grub2 needs to be reinstalled as documented in the 'Reinstalling GRUB 2 on BIOS-Based Machines' section of the Red Hat Enterprise Linux 7 System Administrator's Guide linked to in the References section. No manual action is needed on UEFI-based machines.

Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

* A flaw was found in the way the Linux kernel's file system implementation handled rename operations in which the source was inside and the destination was outside of a bind mount. A privileged user inside a container could use this flaw to escape the bind mount and, potentially, escalate their privileges on the system.
(CVE-2015-2925, Important)

* It was found that the x86 ISA (Instruction Set Architecture) is prone to a denial of service attack inside a virtualized environment in the form of an infinite loop in the microcode due to the way (sequential) delivering of benign exceptions such as #AC (alignment check exception) and #DB (debug exception) is handled. A privileged user inside a guest could use these flaws to create denial of service conditions on the host kernel. (CVE-2015-5307, CVE-2015-8104, Important)

* A race condition flaw was found in the way the Linux kernel's IPC subsystem initialized certain fields in an IPC object structure that were later used for permission checking before inserting the object into a globally visible list. A local, unprivileged user could potentially use this flaw to elevate their privileges on the system.
(CVE-2015-7613, Important)

* It was found that the Linux kernel's keys subsystem did not correctly garbage collect uninstantiated keyrings. A local attacker could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2015-7872, Important)

Red Hat would like to thank Ben Serebrin of Google Inc. for reporting the CVE-2015-5307 issue.

This update also fixes the following bugs :

* Previously, Human Interface Device (HID) ran a report on an unaligned buffer, which could cause a page fault interrupt and an oops when the end of the report was read. This update fixes this bug by padding the end of the report with extra bytes, so the reading of the report never crosses a page boundary. As a result, a page fault and subsequent oops no longer occur. (BZ#1268203)

* The NFS client was previously failing to detect a directory loop for some NFS server directory structures. This failure could cause NFS inodes to remain referenced after attempting to unmount the file system, leading to a kernel crash. Loop checks have been added to VFS, which effectively prevents this problem from occurring. (BZ#1272858)

* Due to a race whereby the nfs_wb_pages_cancel() and nfs_commit_release_pages() calls both removed a request from the nfs_inode struct type, the kernel panicked with negative nfs_inode.npages count. The provided upstream patch performs the required serialization by holding the inode i_lock over the check of PagePrivate and locking the request, thus preventing the race and kernel panic from occurring. (BZ#1273721)

* Due to incorrect URB_ISO_ASAP semantics, playing an audio file using a USB sound card could previously fail for some hardware configurations. This update fixes the bug, and playing audio from a USB sound card now works as expected. (BZ#1273916)

* Inside hugetlb, region data structures were protected by a combination of a memory map semaphore and a single hugetlb instance mutex. However, a page-fault scalability improvement backported to the kernel on previous releases removed the single hugetlb instance mutex and introduced a new mutex table, making the locking combination insufficient, leading to possible race windows that could cause corruption and undefined behavior. This update fixes the problem by introducing a required spinlock to the region tracking functions for proper serialization. The problem only affects software using huge pages through hugetlb interface. (BZ#1274599)

All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

LibreOffice is an open source, community-developed office productivity suite. It includes key desktop applications, such as a word processor, a spreadsheet, a presentation manager, a formula editor, and a drawing program. LibreOffice replaces OpenOffice and provides a similar but enhanced and extended office suite.

It was discovered that LibreOffice did not properly restrict automatic link updates. By tricking a victim into opening specially crafted documents, an attacker could possibly use this flaw to disclose contents of files accessible by the victim. (CVE-2015-4551)

An integer underflow flaw leading to a heap-based buffer overflow when parsing PrinterSetup data was discovered. By tricking a user into opening a specially crafted document, an attacker could possibly exploit this flaw to execute arbitrary code with the privileges of the user opening the file. (CVE-2015-5212)

An integer overflow flaw, leading to a heap-based buffer overflow, was found in the way LibreOffice processed certain Microsoft Word .doc files. By tricking a user into opening a specially crafted Microsoft Word .doc document, an attacker could possibly use this flaw to execute arbitrary code with the privileges of the user opening the file. (CVE-2015-5213)

It was discovered that LibreOffice did not properly sanity check bookmark indexes. By tricking a user into opening a specially crafted document, an attacker could possibly use this flaw to execute arbitrary code with the privileges of the user opening the file.
(CVE-2015-5214)

OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols, as well as a full-strength, general purpose cryptography library.

A NULL pointer dereference flaw was found in the way OpenSSL verified signatures using the RSA PSS algorithm. A remote attacked could possibly use this flaw to crash a TLS/SSL client using OpenSSL, or a TLS/SSL server using OpenSSL if it enabled client authentication.
(CVE-2015-3194)

A memory leak vulnerability was found in the way OpenSSL parsed PKCS#7 and CMS data. A remote attacker could use this flaw to cause an application that parses PKCS#7 or CMS data from untrusted sources to use an excessive amount of memory and possibly crash. (CVE-2015-3195)

A race condition flaw, leading to a double free, was found in the way OpenSSL handled pre-shared key (PSK) identify hints. A remote attacker could use this flaw to crash a multi-threaded SSL/TLS client using OpenSSL. (CVE-2015-3196)

All openssl users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. For the update to take effect, all services linked to the OpenSSL library must be restarted, or the system rebooted.

Red Hat Product Security has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The libpng packages contain a library of functions for creating and manipulating PNG (Portable Network Graphics) image format files.

It was discovered that the png_get_PLTE() and png_set_PLTE() functions of libpng did not correctly calculate the maximum palette sizes for bit depths of less than 8. In case an application tried to use these functions in combination with properly calculated palette sizes, this could lead to a buffer overflow or out-of-bounds reads. An attacker could exploit this to cause a crash or potentially execute arbitrary code by tricking an unsuspecting user into processing a specially crafted PNG image. However, the exact impact is dependent on the application using the library. (CVE-2015-8126, CVE-2015-8472)

All libpng users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.

Git is a distributed revision control system with a decentralized architecture. As opposed to centralized version control systems with a client-server model, Git ensures that each working copy of a Git repository is an exact copy with complete revision history. This not only allows the user to work on and contribute to projects without the need to have permission to push the changes to their official repositories, but also makes it possible for the user to work with no network connection.

A flaw was found in the way the git-remote-ext helper processed certain URLs. If a user had Git configured to automatically clone submodules from untrusted repositories, an attacker could inject commands into the URL of a submodule, allowing them to execute arbitrary code on the user's system. (BZ#1269794)

All git users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.

Red Hat would like to thank Ben Serebrin of Google Inc. for reporting the CVE-2015-5307 issue.

This update also fixes the following bugs :

* On Intel Xeon v5 platforms, the processor frequency was always tied to the highest possible frequency. Switching p-states on these client platforms failed. This update sets the idle frequency, busy frequency, and processor frequency values by determining the range and adjusting the minimal and maximal percent limit values. Now, switching p-states on the aforementioned client platforms proceeds successfully.
(BZ#1273926)

* Due to a validation error of in-kernel memory-mapped I/O (MMIO) tracing, a VM became previously unresponsive when connected to Red Hat Enterprise Virtualization Hypervisor. The provided patch fixes this bug by dropping the check in MMIO handler, and a VM continues running as expected. (BZ#1275150)

* Due to retry-able command errors, the NVMe driver previously leaked I/O descriptors and DMA mappings. As a consequence, the kernel could become unresponsive during the hot-unplug operation if a driver was removed. This update fixes the driver memory leak bug on command retries, and the kernel no longer hangs in this situation.
(BZ#1279792)

* The hybrid_dma_data() function was not initialized before use, which caused an invalid memory access when hot-plugging a PCI card. As a consequence, a kernel oops occurred. The provided patch makes sure hybrid_dma_data() is initialized before use, and the kernel oops no longer occurs in this situation. (BZ#1279793)

* When running PowerPC (PPC) KVM guests and the host was experiencing a lot of page faults, for example because it was running low on memory, the host sometimes triggered an incorrect kind of interrupt in the guest: a data storage exception instead of a data segment exception. This caused a kernel panic of the PPC KVM guest. With this update, the host kernel synthesizes a segment fault if the corresponding Segment Lookaside Buffer (SLB) lookup fails, which prevents the kernel panic from occurring. (BZ#1281423)

* The kernel accessed an incorrect area of the khugepaged process causing Logical Partitioning (LPAR) to become unresponsive, and an oops occurred in medlp5. The backported upstream patch prevents an LPAR hang, and the oops no longer occurs. (BZ#1281424)

* When the sctp module was loaded and a route to an association endpoint was removed after receiving an Out-of-The-Blue (OOTB) chunk but before incrementing the 'dropped because of missing route' SNMP statistic, a Null Pointer Dereference kernel panic previously occurred. This update fixes the race condition between OOTB response and route removal. (BZ#1281426)

* The cpuscaling test of the certification test suite previously failed due to a rounding bug in the intel-pstate driver. This bug has been fixed and the cpuscaling test now passes. (BZ#1281491)

All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

The Jakarta/Apache Commons Collections library provides new interfaces, implementations, and utilities to extend the features of the Java Collections Framework.

It was found that the Apache commons-collections library permitted code execution when deserializing objects involving a specially constructed chain of classes. A remote attacker could use this flaw to execute arbitrary code with the permissions of the application using the commons-collections library. (CVE-2015-7501)

With this update, deserialization of certain classes in the commons-collections library is no longer allowed. Applications that require those classes to be deserialized can use the system property 'org.apache.commons.collections.enableUnsafeSerialization' to re-enable their deserialization.

Further information about this security flaw may be found at:
https://access.redhat.com/solutions/2045023

All users of jakarta-commons-collections are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. All running applications using the commons-collections library must be restarted for the update to take effect.

Red Hat Product Security has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

libreport provides an API for reporting different problems in applications to different bug targets, such as Bugzilla, FTP, and Trac. ABRT (Automatic Bug Reporting Tool) uses libreport.

It was found that ABRT may have exposed unintended information to Red Hat Bugzilla during crash reporting. A bug in the libreport library caused changes made by a user in files included in a crash report to be discarded. As a result, Red Hat Bugzilla attachments may contain data that was not intended to be made public, including host names, IP addresses, or command line options. (CVE-2015-5302)

This flaw did not affect default installations of ABRT on Red Hat Enterprise Linux as they do not post data to Red Hat Bugzilla. This feature can however be enabled, potentially impacting modified ABRT instances.

As a precaution, Red Hat has identified bugs filed by such non-default Red Hat Enterprise Linux users of ABRT and marked them private.

This issue was discovered by Bastien Nocera of Red Hat.

All users of libreport are advised to upgrade to these updated packages, which corrects this issue.

ABRT (Automatic Bug Reporting Tool) is a tool to help users to detect defects in applications and to create a bug report with all the information needed by a maintainer to fix it. It uses a plug-in system to extend its functionality. libreport provides an API for reporting different problems in applications to different bug targets, such as Bugzilla, FTP, and Trac.

It was found that the ABRT debug information installer (abrt-action-install-debuginfo-to-abrt-cache) did not use temporary directories in a secure way. A local attacker could use the flaw to create symbolic links and files at arbitrary locations as the abrt user. (CVE-2015-5273)

It was discovered that the kernel-invoked coredump processor provided by ABRT did not handle symbolic links correctly when writing core dumps of ABRT programs to the ABRT dump directory (/var/spool/abrt). A local attacker with write access to an ABRT problem directory could use this flaw to escalate their privileges. (CVE-2015-5287)

It was found that ABRT may have exposed unintended information to Red Hat Bugzilla during crash reporting.

As a precaution, Red Hat has identified bugs filed by such non-default Red Hat Enterprise Linux users of ABRT and marked them private.

Red Hat would like to thank Philip Pettersson of Samsung for reporting the CVE-2015-5273 and CVE-2015-5287 issues. The CVE-2015-5302 issue was discovered by Bastien Nocera of Red Hat.

All users of abrt and libreport are advised to upgrade to these updated packages, which contain backported patches to correct these issues.

Updated unbound packages that fix one security issue and several bugs are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The unbound packages provide a validating, recursive, and caching DNS or DNSSEC resolver.

A denial of service flaw was found in unbound that an attacker could use to trick the unbound resolver into following an endless loop of delegations, consuming an excessive amount of resources.
(CVE-2014-8602)

This update also fixes the following bugs :

* Prior to this update, there was a mistake in the time configuration in the cron job invoking unbound-anchor to update the root zone key.
Consequently, unbound-anchor was invoked once a month instead of every day, thus not complying with RFC 5011. The cron job has been replaced with a systemd timer unit that is invoked on a daily basis. Now, the root zone key validity is checked daily at a random time within a 24-hour window, and compliance with RFC 5011 is ensured. (BZ#1180267)

* Previously, the unbound packages were installing their configuration file for the systemd-tmpfiles utility into the /etc/tmpfiles.d/ directory. As a consequence, changes to unbound made by the administrator in /etc/tmpfiles.d/ could be overwritten on package reinstallation or update. To fix this bug, unbound has been amended to install the configuration file into the /usr/lib/tmpfiles.d/ directory. As a result, the system administrator's configuration in /etc/tmpfiles.d/ is preserved, including any changes, on package reinstallation or update. (BZ#1180995)

* The unbound server default configuration included validation of DNS records using the DNSSEC Look-aside Validation (DLV) registry. The Internet Systems Consortium (ISC) plans to deprecate the DLV registry service as no longer needed, and unbound could execute unnecessary steps. Therefore, the use of the DLV registry has been removed from the unbound server default configuration. Now, unbound does not try to perform DNS records validation using the DLV registry. (BZ#1223339)

All unbound users are advised to upgrade to these updated packages, which contain backported patches to correct these issues.

Updated autofs packages that fix one security issue, several bugs, and add one enhancement are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The autofs utility controls the operation of the automount daemon. The daemon automatically mounts file systems when in use and unmounts them when they are not busy.

It was found that program-based automounter maps that used interpreted languages such as Python used standard environment variables to locate and load modules of those languages. A local attacker could potentially use this flaw to escalate their privileges on the system.
(CVE-2014-8169)

Note: This issue has been fixed by adding the 'AUTOFS_' prefix to the affected environment variables so that they are not used to subvert the system. A configuration option ('force_standard_program_map_env') to override this prefix and to use the environment variables without the prefix has been added. In addition, warnings have been added to the manual page and to the installed configuration file. Now, by default the standard variables of the program map are provided only with the prefix added to its name.

Red Hat would like to thank the Georgia Institute of Technology for reporting this issue.

Notably, this update fixes the following bugs :

* When the 'ls *' command was run in the root of an indirect mount, autofs attempted to literally mount the wildcard character (*) causing it to be added to the negative cache. If done before a valid mount, autofs then failed on further mount attempts inside the mount point, valid or not. This has been fixed, and wildcard map entries now function in the described situation. (BZ#1166457)

* When autofs encountered a syntax error consisting of a duplicate entry in a multimap entry, it reported an error and did not mount the map entry. With this update, autofs has been amended to report the problem in the log to alert the system administrator and use the last seen instance of the duplicate entry rather than fail. (BZ#1205600)

* In the ldap and sss lookup modules, the map reading functions did not distinguish between the 'no entry found' and 'service not available' errors. Consequently, when the 'service not available' response was returned from a master map read, autofs did not update the mounts. An 'entry not found' return does not prevent the map update, so the ldap and sss lookup modules were updated to distinguish between these two returns and now work as expected. (BZ#1233065)

In addition, this update adds the following enhancement :

* The description of the configuration parameter map_hash_table_size was missing from the autofs.conf(5) man page and its description in the configuration file comments was insufficient. A description of the parameter has been added to autofs.conf(5), and the configuration file comments have been updated. (BZ#1238573)

All autofs users are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add this enhancement.

Updated grub2 packages that fix one security issue, several bugs, and add one enhancement are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The grub2 packages provide version 2 of the Grand Unified Bootloader (GRUB), a highly configurable and customizable bootloader with modular architecture. The packages support a variety of kernel formats, file systems, computer architectures, and hardware devices.

It was discovered that grub2 builds for EFI systems contained modules that were not suitable to be loaded in a Secure Boot environment. An attacker could use this flaw to circumvent the Secure Boot mechanisms and load non-verified code. Attacks could use the boot menu if no password was set, or the grub2 configuration file if the attacker has root privileges on the system. (CVE-2015-5281)

This update also fixes the following bugs :

* In one of the earlier updates, GRUB2 was modified to escape forward slash (/) characters in several different places. In one of these places, the escaping was unnecessary and prevented certain types of kernel command-line arguments from being passed to the kernel correctly. With this update, GRUB2 no longer escapes the forward slash characters in the mentioned place, and the kernel command-line arguments work as expected. (BZ#1125404)

* Previously, GRUB2 relied on a timing mechanism provided by legacy hardware, but not by the Hyper-V Gen2 hypervisor, to calibrate its timer loop. This prevented GRUB2 from operating correctly on Hyper-V Gen2. This update modifies GRUB2 to use a different mechanism on Hyper-V Gen2 to calibrate the timing. As a result, Hyper-V Gen2 hypervisors now work as expected. (BZ#1150698)

* Prior to this update, users who manually configured GRUB2 to use the built-in GNU Privacy Guard (GPG) verification observed the following error on boot :

alloc magic is broken at [addr]: [value] Aborted.

Consequently, the boot failed. The GRUB2 built-in GPG verification has been modified to no longer free the same memory twice. As a result, the mentioned error no longer occurs. (BZ#1167977)

* Previously, the system sometimes did not recover after terminating unexpectedly and failed to reboot. To fix this problem, the GRUB2 packages now enforce file synchronization when creating the GRUB2 configuration file, which ensures that the required configuration files are written to disk. As a result, the system now reboots successfully after crashing. (BZ#1212114)

* Previously, if an unconfigured network driver instance was selected and configured when the GRUB2 bootloader was loaded on a different instance, GRUB2 did not receive notifications of the Address Resolution Protocol (ARP) replies. Consequently, GRUB2 failed with the following error message :

error: timeout: could not resolve hardware address.

With this update, GRUB2 selects the network driver instance from which it was loaded. As a result, ARP packets are processed correctly.
(BZ#1257475)

In addition, this update adds the following enhancement :

* Sorting of GRUB2 boot menu has been improved. GRUB2 now uses the rpmdevtools package to sort available kernels and the configuration file is being generated correctly with the most recent kernel version listed at the top. (BZ#1124074)

All grub2 users are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add this enhancement.

Updated wireshark packages that fix multiple security issues, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The wireshark packages contain a network protocol analyzer used to capture and browse the traffic running on a computer network.

Several denial of service flaws were found in Wireshark. Wireshark could crash or stop responding if it read a malformed packet off a network, or opened a malicious dump file. (CVE-2015-2188, CVE-2015-2189, CVE-2015-2191, CVE-2015-3810, CVE-2015-3811, CVE-2015-3812, CVE-2015-3813, CVE-2014-8710, CVE-2014-8711, CVE-2014-8712, CVE-2014-8713, CVE-2014-8714, CVE-2015-0562, CVE-2015-0563, CVE-2015-0564, CVE-2015-3182, CVE-2015-6243, CVE-2015-6244, CVE-2015-6245, CVE-2015-6246, CVE-2015-6248)

The CVE-2015-3182 issue was discovered by Martin Zember of Red Hat.

The wireshark packages have been upgraded to upstream version 1.10.14, which provides a number of bug fixes and enhancements over the previous version. (BZ#1238676)

This update also fixes the following bug :

* Prior to this update, when using the tshark utility to capture packets over the interface, tshark failed to create output files in the .pcap format even if it was specified using the '-F' option. This bug has been fixed, the '-F' option is now honored, and the result saved in the .pcap format as expected. (BZ#1227199)

In addition, this update adds the following enhancement :

* Previously, wireshark included only microseconds in the .pcapng format. With this update, wireshark supports nanosecond time stamp precision to allow for more accurate time stamps. (BZ#1213339)

All wireshark users are advised to upgrade to these updated packages, which correct these issues and add these enhancements. All running instances of Wireshark must be restarted for the update to take effect.

Updated pacemaker packages that fix one security issue, several bugs, and add two enhancements are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The Pacemaker Resource Manager is a collection of technologies working together to provide data integrity and the ability to maintain application availability in the event of a failure.

A flaw was found in the way pacemaker, a cluster resource manager, evaluated added nodes in certain situations. A user with read-only access could potentially assign any other existing roles to themselves and then add privileges to other users as well. (CVE-2015-1867)

The pacemaker packages have been upgraded to upstream version 1.1.13, which provides a number of bug fixes and enhancements over the previous version. (BZ#1234680)

This update also fixes the following bugs :

* When a Pacemaker cluster included an Apache resource, and Apache's mod_systemd module was enabled, systemd rejected notifications sent by Apache. As a consequence, a large number of errors in the following format appeared in the system log :

Got notification message from PID XXXX, but reception only permitted for PID YYYY

With this update, the lrmd daemon now unsets the 'NOTIFY_SOCKET' variable in the described circumstances, and these error messages are no longer logged. (BZ#1150184)

* Previously, specifying a remote guest node as a part of a group resource in a Pacemaker cluster caused the node to stop working. This update adds support for remote guests in Pacemaker group resources, and the described problem no longer occurs. (BZ#1168637)

* When a resource in a Pacemaker cluster failed to start, Pacemaker updated the resource's last failure time and incremented its fail count even if the 'on-fail=ignore' option was used. This in some cases caused unintended resource migrations when a resource start failure occurred. Now, Pacemaker does not update the fail count when 'on-fail=ignore' is used. As a result, the failure is displayed in the cluster status output, but is properly ignored and thus does not cause resource migration. (BZ#1200849)

* Previously, Pacemaker supported semicolon characters (';') as delimiters when parsing the pcmk_host_map string, but not when parsing the pcmk_host_list string. To ensure consistent user experience, semicolons are now supported as delimiters for parsing pcmk_host_list, as well. (BZ#1206232)

In addition, this update adds the following enhancements :

* If a Pacemaker location constraint has the 'resource-discovery=never' option, Pacemaker now does not attempt to determine whether a specified service is running on the specified node. In addition, if multiple location constraints for a given resource specify 'resource-discovery=exclusive', then Pacemaker attempts resource discovery only on the nodes specified in those constraints. This allows Pacemaker to skip resource discovery on nodes where attempting the operation would lead to error or other undesirable behavior. (BZ#1108853)

* The procedure of configuring fencing for redundant power supplies has been simplified in order to prevent multiple nodes accessing cluster resources at the same time and thus causing data corruption.
For further information, see the 'Fencing: Configuring STONITH' chapter of the High Availability Add-On Reference manual. (BZ#1206647)

* The output of the 'crm_mon' and 'pcs_status' commands has been modified to be clearer and more concise, and thus easier to read when reporting the status of a Pacemaker cluster with a large number of remote nodes and cloned resources. (BZ#1115840)

All pacemaker users are advised to upgrade to these updated packages, which correct these issues and add these enhancements.

Updated squid packages that fix one security issue and two bugs are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

Squid is a high-performance proxy caching server for web clients, supporting FTP, Gopher, and HTTP data objects.

It was found that Squid configured with client-first SSL-bump did not correctly validate X.509 server certificate host name fields. A man-in-the-middle attacker could use this flaw to spoof a Squid server using a specially crafted X.509 certificate. (CVE-2015-3455)

This update fixes the following bugs :

* Previously, the squid process did not handle file descriptors correctly when receiving Simple Network Management Protocol (SNMP) requests. As a consequence, the process gradually accumulated open file descriptors. This bug has been fixed and squid now handles SNMP requests correctly, closing file descriptors when necessary.
(BZ#1198778)

* Under high system load, the squid process sometimes terminated unexpectedly with a segmentation fault during reboot. This update provides better memory handling during reboot, thus fixing this bug.
(BZ#1225640)

Users of squid are advised to upgrade to these updated packages, which fix these bugs. After installing this update, the squid service will be restarted automatically.

Updated openhpi packages that fix one security issue, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

OpenHPI is an open source project created with the intent of providing an implementation of the SA Forum's Hardware Platform Interface (HPI).
HPI provides an abstracted interface to managing computer hardware, typically for chassis and rack based servers. HPI includes resource modeling, access to and control over sensor, control, watchdog, and inventory data associated with resources, abstracted System Event Log interfaces, hardware events and alerts, and a managed hotswap interface.

It was found that the '/var/lib/openhpi' directory provided by OpenHPI used world-writeable and world-readable permissions. A local user could use this flaw to view, modify, and delete OpenHPI-related data, or even fill up the storage device hosting the /var/lib directory.
(CVE-2015-3248)

This issue was discovered by Marko Myllynen of Red Hat.

The openhpi packages have been upgraded to upstream version 3.4.0, which provides a number of bug fixes and enhancements over the previous version. (BZ#1127908)

This update also fixes the following bug :

* Network timeouts were handled incorrectly in the openhpid daemon. As a consequence, network connections could fail when external plug-ins were used. With this update, handling of network socket timeouts has been improved in openhpid, and the described problem no longer occurs.
(BZ#1208127)

All openhpi users are advised to upgrade to these updated packages, which correct these issues and add these enhancements.

Updated cups-filters packages that fix two security issues, several bugs, and add one enhancement are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The cups-filters packages contain back ends, filters, and other software that was once part of the core Common UNIX Printing System (CUPS) distribution but is now maintained independently.

A heap-based buffer overflow flaw and an integer overflow flaw leading to a heap-based buffer overflow were discovered in the way the texttopdf utility of cups-filter processed print jobs with a specially crafted line size. An attacker able to submit print jobs could use these flaws to crash texttopdf or, possibly, execute arbitrary code with the privileges of the 'lp' user. (CVE-2015-3258, CVE-2015-3279)

The CVE-2015-3258 issue was discovered by Petr Sklenar of Red Hat.

Notably, this update also fixes the following bug :

* Previously, when polling CUPS printers from a CUPS server, when a printer name contained an underscore (_), the client displayed the name containing a hyphen (-) instead. This made the print queue unavailable. With this update, CUPS allows the underscore character in printer names, and printers appear as shown on the CUPS server as expected. (BZ#1167408)

In addition, this update adds the following enhancement :

* Now, the information from local and remote CUPS servers is cached during each poll, and the CUPS server load is reduced. (BZ#1191691)

All cups-filters users are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add this enhancement.

Updated sssd packages that fix one security issue, multiple bugs, and add various enhancements are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The System Security Services Daemon (SSSD) service provides a set of daemons to manage access to remote directories and authentication mechanisms.

It was found that SSSD's Privilege Attribute Certificate (PAC) responder plug-in would leak a small amount of memory on each authentication request. A remote attacker could potentially use this flaw to exhaust all available memory on the system by making repeated requests to a Kerberized daemon application configured to authenticate using the PAC responder plug-in. (CVE-2015-5292)

The sssd packages have been upgraded to upstream version 1.13.0, which provides a number of bug fixes and enhancements over the previous version. (BZ#1205554)

Several enhancements are described in the Red Hat Enterprise Linux 7.2 Release Notes, linked to in the References section :

* SSSD smart card support (BZ#854396)

* Cache authentication in SSSD (BZ#910187)

* SSSD supports overriding automatically discovered AD site (BZ#1163806)

* SSSD can now deny SSH access to locked accounts (BZ#1175760)

* SSSD enables UID and GID mapping on individual clients (BZ#1183747)

* Background refresh of cached entries (BZ#1199533)

* Multi-step prompting for one-time and long-term passwords (BZ#1200873)

* Caching for initgroups operations (BZ#1206575)

Bugs fixed :

* When the SELinux user content on an IdM server was set to an empty string, the SSSD SELinux evaluation utility returned an error.
(BZ#1192314)

* If the ldap_child process failed to initialize credentials and exited with an error multiple times, operations that create files in some cases started failing due to an insufficient amount of i-nodes.
(BZ#1198477)

* The SRV queries used a hard-coded TTL timeout, and environments that wanted the SRV queries to be valid for a certain time only were blocked. Now, SSSD parses the TTL value out of the DNS packet.
(BZ#1199541)

* Previously, initgroups operation took an excessive amount of time.
Now, logins and ID processing are faster for setups with AD back end and disabled ID mapping. (BZ#1201840)

* When an IdM client with Red Hat Enterprise Linux 7.1 or later was connecting to a server with Red Hat Enterprise Linux 7.0 or earlier, authentication with an AD trusted domain caused the sssd_be process to terminate unexpectedly. (BZ#1202170)

* If replication conflict entries appeared during HBAC processing, the user was denied access. Now, the replication conflict entries are skipped and users are permitted access. (BZ#1202245)

* The array of SIDs no longer contains an uninitialized value and SSSD no longer crashes. (BZ#1204203)

* SSSD supports GPOs from different domain controllers and no longer crashes when processing GPOs from different domain controllers.
(BZ#1205852)

* SSSD could not refresh sudo rules that contained groups with special characters, such as parentheses, in their name. (BZ#1208507)

* The IPA names are not qualified on the client side if the server already qualified them, and IdM group members resolve even if default_domain_suffix is used on the server side. (BZ#1211830)

* The internal cache cleanup task has been disabled by default to improve performance of the sssd_be process. (BZ#1212489)

* Now, default_domain_suffix is not considered anymore for autofs maps. (BZ#1216285)

* The user can set subdomain_inherit=ignore_group-members to disable fetching group members for trusted domains. (BZ#1217350)

* The group resolution failed with an error message: 'Error: 14 (Bad address)'. The binary GUID handling has been fixed. (BZ#1226119)

Enhancements added :

* The description of default_domain_suffix has been improved in the manual pages. (BZ#1185536)

* With the new '%0' template option, users on SSSD IdM clients can now use home directories set on AD. (BZ#1187103)

All sssd users are advised to upgrade to these updated packages, which correct these issues and add these enhancements.

Updated net-snmp packages that fix one security issue and several bugs are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The net-snmp packages provide various libraries and tools for the Simple Network Management Protocol (SNMP), including an SNMP library, an extensible agent, tools for requesting or setting information from SNMP agents, tools for generating and handling SNMP traps, a version of the netstat command which uses SNMP, and a Tk/Perl Management Information Base (MIB) browser.

A denial of service flaw was found in the way snmptrapd handled certain SNMP traps when started with the '-OQ' option. If an attacker sent an SNMP trap containing a variable with a NULL type where an integer variable type was expected, it would cause snmptrapd to crash.
(CVE-2014-3565)

This update also fixes the following bugs :

* Previously, the clientaddr option in the snmp.conf file affected outgoing messages sent only over IPv4. With this release, outgoing IPv6 messages are correctly sent from the interface specified by clientaddr. (BZ#1190679)

* The Net-SNMP daemon, snmpd, did not properly clean memory when reloading its configuration file with multiple 'exec' entries.
Consequently, the daemon terminated unexpectedly. Now, the memory is properly cleaned, and snmpd no longer crashes on reload. (BZ#1228893)

* Prior to this update, snmpd did not parse complete IPv4 traffic statistics, but reported the number of received or sent bytes in the IP-MIB::ipSystemStatsTable only for IPv6 packets and not for IPv4.
This affected objects ipSystemStatsInOctets, ipSystemStatsOutOctets, ipSystemStatsInMcastOctets, and ipSystemStatsOutMcastOctets. Now, the statistics reported by snmpd are collected for IPv4 as well.
(BZ#1235697)

* The Net-SNMP daemon, snmpd, did not correctly detect the file system change from read-only to read-write. Consequently, after remounting the file system into the read-write mode, the daemon reported it to be still in the read-only mode. A patch has been applied, and snmpd now detects the mode changes as expected. (BZ#1241897)

All net-snmp users are advised to upgrade to these updated packages, which contain backported patches to correct these issues.

Updated NetworkManager packages that fix two security issues, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

NetworkManager is a system network service that manages network devices and connections.

It was discovered that NetworkManager would set device MTUs based on MTU values received in IPv6 RAs (Router Advertisements), without sanity checking the MTU value first. A remote attacker could exploit this flaw to create a denial of service attack, by sending a specially crafted IPv6 RA packet to disturb IPv6 communication. (CVE-2015-0272)

A flaw was found in the way NetworkManager handled router advertisements. An unprivileged user on a local network could use IPv6 Neighbor Discovery ICMP to broadcast a non-route with a low hop limit, causing machines to lower the hop limit on existing IPv6 routes. If this limit is small enough, IPv6 packets would be dropped before reaching the final destination. (CVE-2015-2924)

The network-manager-applet and NetworkManager-libreswan packages have been upgraded to upstream versions 1.0.6, and provide a number of bug fixes and enhancements over the previous versions. (BZ#1177582, BZ#1243057)

Bugs :

* It was not previously possible to set the Wi-Fi band to the 'a' or 'bg' values to lock to a specific frequency band. NetworkManager has been fixed, and it now sets the wpa_supplicant's 'freq_list' option correctly, which enables proper Wi-Fi band locking. (BZ#1254461)

* NetworkManager immediately failed activation of devices that did not have a carrier early in the boot process. The legacy network.service then reported activation failure. Now, NetworkManager has a grace period during which it waits for the carrier to appear. Devices that have a carrier down for a short time on system startup no longer cause the legacy network.service to fail. (BZ#1079353)

* NetworkManager brought down a team device if the teamd service managing it exited unexpectedly, and the team device was deactivated.
Now, NetworkManager respawns the teamd instances that disappear and is able to recover from a teamd failure avoiding disruption of the team device operation. (BZ#1145988)

* NetworkManager did not send the FQDN DHCP option even if host name was set to FQDN. Consequently, Dynamic DNS (DDNS) setups failed to update the DNS records for clients running NetworkManager. Now, NetworkManager sends the FQDN option with DHCP requests, and the DHCP server is able to create DNS records for such clients. (BZ#1212597)

* The command-line client was not validating the vlan.flags property correctly, and a spurious warning message was displayed when the nmcli tool worked with VLAN connections. The validation routine has been fixed, and the warning message no longer appears. (BZ#1244048)

* NetworkManager did not propagate a media access control (MAC) address change from a bonding interface to a VLAN interface on top of it. Consequently, a VLAN interface on top of a bond used an incorrect MAC address. Now, NetworkManager synchronizes the addresses correctly.
(BZ#1264322)

Enhancements :

* IPv6 Privacy extensions are now enabled by default. NetworkManager checks the per-network configuration files, NetworkManager.conf, and then falls back to '/proc/sys/net/ipv6/conf/default/use_tempaddr' to determine and set IPv6 privacy settings at device activation.
(BZ#1187525)

* The NetworkManager command-line tool, nmcli, now allows setting the wake-on-lan property to 0 ('none', 'disable', 'disabled').
(BZ#1260584)

* NetworkManager now provides information about metered connections.
(BZ#1200452)

* NetworkManager daemon and the connection editor now support setting the Maximum Transmission Unit (MTU) of a bond. It is now possible to change MTU of a bond interface in a GUI. (BZ#1177582, BZ#1177860)

* NetworkManager daemon and the connection editor now support setting the MTU of a team, allowing to change MTU of a teaming interface.
(BZ#1255927)

NetworkManager users are advised to upgrade to these updated packages, which correct these issues and add these enhancements.

An updated pcs package that fixes one security issue, several bugs, and add various enhancements is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The pcs package provides a configuration tool for Corosync and Pacemaker. It permits users to easily view, modify and create Pacemaker based clusters. The pcs package includes Rack, which provides a minimal interface between webservers that support Ruby and Ruby frameworks.

A flaw was found in a way Rack processed parameters of incoming requests. An attacker could use this flaw to send a crafted request that would cause an application using Rack to crash. (CVE-2015-3225)

Red Hat would like to thank Ruby upstream developers for reporting this. Upstream acknowledges Tomek Rabczak from the NCC Group as the original reporter.

The pcs package has been upgraded to upstream version 0.9.143, which provides a number of bug fixes and enhancements over the previous version. (BZ#1198265)

The following enhancements are described in more detail in the Red Hat Enterprise Linux 7.2 Release Notes, linked to from the References section :

* The pcs resource move and pcs resource ban commands now display a warning message to clarify the commands' behavior (BZ#1201452)

* New command to move a Pacemaker resource to its preferred node (BZ#1122818)

This update also fixes the following bugs :

* Before this update, a bug caused location, ordering, and colocation constraints related to a resource group to be removed when removing any resource from that group. This bug has been fixed, and the constraints are now preserved until the group has no resources left, and is removed. (BZ#1158537)

* Previously, when a user disabled a resource clone or multi-state resource, and then later enabled a primitive resource within it, the clone or multi-state resource remained disabled. With this update, enabling a resource within a disabled clone or multi-state resource enables it. (BZ#1218979)

* When the web UI displayed a list of resource attributes, a bug caused the list to be truncated at the first '=' character. This update fixes the bug and now the web UI displays lists of resource attributes correctly. (BZ#1243579)

* The documentation for the 'pcs stonith confirm' command was not clear. This could lead to incorrect usage of the command, which could in turn cause data corruption. With this update, the documentation has been improved and the 'pcs stonith confirm' command is now more clearly explained. (BZ#1245264)

* Previously, if there were any unauthenticated nodes, creating a new cluster, adding a node to an existing cluster, or adding a cluster to the web UI failed with the message 'Node is not authenticated'. With this update, when the web UI detects a problem with authentication, the web UI displays a dialog to authenticate nodes as necessary.
(BZ#1158569)

* Previously, the web UI displayed only primitive resources. Thus there was no way to set attributes, constraints and other properties separately for a parent resource and a child resource. This has now been fixed, and resources are displayed in a tree structure, meaning all resource elements can be viewed and edited independently.
(BZ#1189857)

In addition, this update adds the following enhancements :

* A dashboard has been added which shows the status of clusters in the web UI. Previously, it was not possible to view all important information about clusters in one place. Now, a dashboard showing the status of clusters has been added to the main page of the web UI.
(BZ#1158566)

* With this update, the pcsd daemon automatically synchronizes pcsd configuration across a cluster. This enables the web UI to be run from any node, allowing management even if any particular node is down.
(BZ#1158577)

* The web UI can now be used to set permissions for users and groups on a cluster. This allows users and groups to have their access restricted to certain operations on certain clusters. (BZ#1158571)

All pcs users are advised to upgrade to this updated package, which corrects these issues and add these enhancements.

Updated netcf packages that fix one security issue, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The netcf packages contain a library for modifying the network configuration of a system. Network configuration is expressed in a platform-independent XML format, which netcf translates into changes to the system's 'native' network configuration files.

A denial of service flaw was found in netcf. A specially crafted interface name could cause an application using netcf (such as the libvirt daemon) to crash. (CVE-2014-8119)

This issue was discovered by Hao Liu of Red Hat.

The netcf packages have been upgraded to upstream version 0.2.8, which provides a number of bug fixes and enhancements over the previous version. (BZ#1206680)

Users of netcf are advised to upgrade to these updated packages, which fix these bugs and add these enhancements.

Updated chrony packages that fix three security issues, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The chrony suite, chronyd and chronyc, is an advanced implementation of the Network Time Protocol (NTP), specially designed to support systems with intermittent connections. It can synchronize the system clock with NTP servers, hardware reference clocks, and manual input.
It can also operate as an NTPv4 (RFC 5905) server or peer to provide a time service to other computers in the network.

An out-of-bounds write flaw was found in the way chrony stored certain addresses when configuring NTP or cmdmon access. An attacker that has the command key and is allowed to access cmdmon (only localhost is allowed by default) could use this flaw to crash chronyd or, possibly, execute arbitrary code with the privileges of the chronyd process.
(CVE-2015-1821)

An uninitialized pointer use flaw was found when allocating memory to save unacknowledged replies to authenticated command requests. An attacker that has the command key and is allowed to access cmdmon (only localhost is allowed by default) could use this flaw to crash chronyd or, possibly, execute arbitrary code with the privileges of the chronyd process. (CVE-2015-1822)

A denial of service flaw was found in the way chrony hosts that were peering with each other authenticated themselves before updating their internal state variables. An attacker could send packets to one peer host, which could cascade to other peers, and stop the synchronization process among the reached peers. (CVE-2015-1853)

These issues were discovered by Miroslav Lichvar of Red Hat.

The chrony packages have been upgraded to upstream version 2.1.1, which provides a number of bug fixes and enhancements over the previous version. Notable enhancements include :

* Updated to NTP version 4 (RFC 5905)

* Added pool directive to specify pool of NTP servers

* Added leapsecmode directive to select how to correct clock for leap second

* Added smoothtime directive to smooth served time and enable leap smear

* Added asynchronous name resolving with POSIX threads

* Ready for year 2036 (next NTP era)

* Improved clock control

* Networking code reworked to open separate client sockets for each NTP server

(BZ#1117882)

This update also fixes the following bug :

* The chronyd service previously assumed that network interfaces specified with the 'bindaddress' directive were ready when the service was started. This could cause chronyd to fail to bind an NTP server socket to the interface if the interface was not ready. With this update, chronyd uses the IP_FREEBIND socket option, enabling it to bind to an interface later, not only when the service starts.
(BZ#1169353)

In addition, this update adds the following enhancement :

* The chronyd service now supports four modes of handling leap seconds, configured using the 'leapsecmode' option. The clock can be either stepped by the kernel (the default 'system' mode), stepped by chronyd ('step' mode), slowly adjusted by slewing ('slew' mode), or the leap second can be ignored and corrected later in normal operation ('ignore' mode). If you select slewing, the correction will always start at 00:00:00 UTC and will be applied at a rate specified in the 'maxslewrate' option. (BZ#1206504)

All chrony users are advised to upgrade to these updated packages, which correct these issues and add these enhancements.

Updated rest packages that fix one security issue are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The rest library was designed to make it easier to access web services that claim to be RESTful. A RESTful service should have URLs that represent remote objects, which methods can then be called on.

It was found that the OAuth implementation in librest, a helper library for RESTful services, incorrectly truncated the pointer returned by the rest_proxy_call_get_url call. An attacker could use this flaw to crash an application using the librest library.
(CVE-2015-2675)

All users of rest are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. After installing the update, all applications using librest must be restarted for the update to take effect.

Updated tigervnc packages that fix two security issues, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Virtual Network Computing (VNC) is a remote display system which allows users to view a computing desktop environment not only on the machine where it is running, but from anywhere on the Internet and from a wide variety of machine architectures. TigerVNC is a suite of VNC servers and clients. The tigervnc packages contain a client which allows users to connect to other desktops running a VNC server.

An integer overflow flaw, leading to a heap-based buffer overflow, was found in the way TigerVNC handled screen sizes. A malicious VNC server could use this flaw to cause a client to crash or, potentially, execute arbitrary code on the client. (CVE-2014-8240)

A NULL pointer dereference flaw was found in TigerVNC's XRegion. A malicious VNC server could use this flaw to cause a client to crash.
(CVE-2014-8241)

The tigervnc packages have been upgraded to upstream version 1.3.1, which provides a number of bug fixes and enhancements over the previous version. (BZ#1199453)

This update also fixes the following bug :

* The position of the mouse cursor in the VNC session was not correctly communicated to the VNC viewer, resulting in cursor misplacement. The method of displaying the remote cursor has been changed, and cursor movements on the VNC server are now accurately reflected on the VNC client. (BZ#1100661)

All tigervnc users are advised to upgrade to these updated packages, which correct these issues and add these enhancements.

Updated ntp packages that fix multiple security issues, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The Network Time Protocol (NTP) is used to synchronize a computer's time with another referenced time source. These packages include the ntpd service which continuously adjusts system time and utilities used to query and configure the ntpd service.

It was found that because NTP's access control was based on a source IP address, an attacker could bypass source IP restrictions and send malicious control and configuration packets by spoofing ::1 addresses.
(CVE-2014-9298, CVE-2014-9751)

A denial of service flaw was found in the way NTP hosts that were peering with each other authenticated themselves before updating their internal state variables. An attacker could send packets to one peer host, which could cascade to other peers, and stop the synchronization process among the reached peers. (CVE-2015-1799)

A flaw was found in the way the ntp-keygen utility generated MD5 symmetric keys on big-endian systems. An attacker could possibly use this flaw to guess generated MD5 keys, which could then be used to spoof an NTP client or server. (CVE-2015-3405)

A stack-based buffer overflow was found in the way the NTP autokey protocol was implemented. When an NTP client decrypted a secret received from an NTP server, it could cause that client to crash.
(CVE-2014-9297, CVE-2014-9750)

It was found that ntpd did not check whether a Message Authentication Code (MAC) was present in a received packet when ntpd was configured to use symmetric cryptographic keys. A man-in-the-middle attacker could use this flaw to send crafted packets that would be accepted by a client or a peer without the attacker knowing the symmetric key.
(CVE-2015-1798)

The CVE-2015-1798 and CVE-2015-1799 issues were discovered by Miroslav Lichvar of Red Hat.

Bug fixes :

* The ntpd service truncated symmetric keys specified in the key file to 20 bytes. As a consequence, it was impossible to configure NTP authentication to work with peers that use longer keys. With this update, the maximum key length has been changed to 32 bytes.
(BZ#1191111)

* The ntpd service could previously join multicast groups only when starting, which caused problems if ntpd was started during system boot before network was configured. With this update, ntpd attempts to join multicast groups every time network configuration is changed.
(BZ#1207014)

* Previously, the ntp-keygen utility used the exponent of 3 when generating RSA keys. Consequently, generating RSA keys failed when FIPS mode was enabled. With this update, ntp-keygen has been modified to use the exponent of 65537, and generating keys in FIPS mode now works as expected. (BZ#1191116)

* The ntpd service dropped incoming NTP packets if their source port was lower than 123 (the NTP port). With this update, ntpd no longer checks the source port number, and clients behind NAT are now able to correctly synchronize with the server. (BZ#1171640)

Enhancements :

* This update adds support for configurable Differentiated Services Code Points (DSCP) in NTP packets, simplifying configuration in large networks where different NTP implementations or versions are using different DSCP values. (BZ#1202828)

* This update adds the ability to configure separate clock stepping thresholds for each direction (backward and forward). Use the 'stepback' and 'stepfwd' options to configure each threshold.
(BZ#1193154)

* Support for nanosecond resolution has been added to the Structural Health Monitoring (SHM) reference clock. Prior to this update, when a Precision Time Protocol (PTP) hardware clock was used as a time source to synchronize the system clock, the accuracy of the synchronization was limited due to the microsecond resolution of the SHM protocol. The nanosecond extension in the SHM protocol now allows sub-microsecond synchronization of the system clock. (BZ#1117702)

All ntp users are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add these enhancements.

Updated glibc packages that fix multiple security issues, several bugs, and add one enhancement are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The glibc packages provide the standard C libraries (libc), POSIX thread libraries (libpthread), standard math libraries (libm), and the Name Server Caching Daemon (nscd) used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly.

It was discovered that, under certain circumstances, glibc's getaddrinfo() function would send DNS queries to random file descriptors. An attacker could potentially use this flaw to send DNS queries to unintended recipients, resulting in information disclosure or data loss due to the application encountering corrupted data.
(CVE-2013-7423)

A buffer overflow flaw was found in the way glibc's gethostbyname_r() and other related functions computed the size of a buffer when passed a misaligned buffer as input. An attacker able to make an application call any of these functions with a misaligned buffer could use this flaw to crash the application or, potentially, execute arbitrary code with the permissions of the user running the application.
(CVE-2015-1781)

A heap-based buffer overflow flaw and a stack overflow flaw were found in glibc's swscanf() function. An attacker able to make an application call the swscanf() function could use these flaws to crash that application or, potentially, execute arbitrary code with the permissions of the user running the application. (CVE-2015-1472, CVE-2015-1473)

An integer overflow flaw, leading to a heap-based buffer overflow, was found in glibc's _IO_wstr_overflow() function. An attacker able to make an application call this function could use this flaw to crash that application or, potentially, execute arbitrary code with the permissions of the user running the application. (BZ#1195762)

A flaw was found in the way glibc's fnmatch() function processed certain malformed patterns. An attacker able to make an application call this function could use this flaw to crash that application.
(BZ#1197730)

The CVE-2015-1781 issue was discovered by Arjun Shankar of Red Hat.

These updated glibc packages also include numerous bug fixes and one enhancement. Space precludes documenting all of these changes in this advisory. For information on the most significant of these changes, users are directed to the following article on the Red Hat Customer Portal :

https://access.redhat.com/articles/2050743

All glibc users are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add these enhancements.

Updated realmd packages that fix two security issues, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The realmd DBus system service manages discovery of and enrollment in realms and domains, such as Active Directory or Identity Management (IdM). The realmd service detects available domains, automatically configures the system, and joins it as an account to a domain.

A flaw was found in the way realmd parsed certain input when writing configuration into the sssd.conf or smb.conf file. A remote attacker could use this flaw to inject arbitrary configurations into these files via a newline character in an LDAP response. (CVE-2015-2704)

It was found that the realm client would try to automatically join an active directory domain without authentication, which could potentially lead to privilege escalation within a specified domain.
(BZ#1205751)

The realmd packages have been upgraded to upstream version 0.16.1, which provides a number of bug fixes and enhancements over the previous version. (BZ#1174911)

This update also fixes the following bugs :

* Joining a Red Hat Enterprise Linux machine to a domain using the realm utility creates /home/domainname/[username]/ directories for domain users. Previously, SELinux labeled the domain users' directories incorrectly. As a consequence, the domain users sometimes experienced problems with SELinux policy. This update modifies the realmd service default behavior so that the domain users' directories are compatible with the standard SELinux policy. (BZ#1241832)

* Previously, the realm utility was unable to join or discover domains with domain names containing underscore (_). The realmd service has been modified to process underscores in domain names correctly, which fixes the described bug. (BZ#1243771)

In addition, this update adds the following enhancement :

* The realmd utility now allows the user to disable automatic ID mapping from the command line. To disable the mapping, pass the '--automatic-id-mapping=no' option to the realmd utility. (BZ#1230941)

All realmd users are advised to upgrade to these updated packages, which correct these issues and add these enhancements.

Updated rubygem-bundler and rubygem-thor packages that fix one security issue, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

Bundler manages an application's dependencies through its entire life, across many machines, systematically and repeatably. Thor is a toolkit for building powerful command-line interfaces.

A flaw was found in the way Bundler handled gems available from multiple sources. An attacker with access to one of the sources could create a malicious gem with the same name, which they could then use to trick a user into installing, potentially resulting in execution of code from the attacker-supplied malicious gem. (CVE-2013-0334)

Bundler has been upgraded to upstream version 1.7.8 and Thor has been upgraded to upstream version 1.19.1, both of which provide a number of bug fixes and enhancements over the previous versions. (BZ#1194243, BZ#1209921)

All rubygem-bundler and rubygem-thor users are advised to upgrade to these updated packages, which correct these issues and add these enhancements.

Updated glibc packages that fix one security issue are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The glibc packages provide the standard C libraries (libc), POSIX thread libraries (libpthread), standard math libraries (libm), and the Name Server Caching Daemon (nscd) used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly.

It was discovered that the nss_files backend for the Name Service Switch in glibc would return incorrect data to applications or corrupt the heap (depending on adjacent heap contents) in certain cases. A local attacker could potentially use this flaw to escalate their privileges. (CVE-2015-5277)

This issue was discovered by Sumit Bose and Lukas Slebodnik of Red Hat.

All glibc users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.

Updated curl packages that fix multiple security issues, several bugs, and add two enhancements are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The curl packages provide the libcurl library and the curl utility for downloading files from servers using various protocols, including HTTP, FTP, and LDAP.

It was found that the libcurl library did not correctly handle partial literal IP addresses when parsing received HTTP cookies. An attacker able to trick a user into connecting to a malicious server could use this flaw to set the user's cookie to a crafted domain, making other cookie-related issues easier to exploit. (CVE-2014-3613)

A flaw was found in the way the libcurl library performed the duplication of connection handles. If an application set the CURLOPT_COPYPOSTFIELDS option for a handle, using the handle's duplicate could cause the application to crash or disclose a portion of its memory. (CVE-2014-3707)

It was discovered that the libcurl library failed to properly handle URLs with embedded end-of-line characters. An attacker able to make an application using libcurl access a specially crafted URL via an HTTP proxy could use this flaw to inject additional headers to the request or construct additional requests. (CVE-2014-8150)

It was discovered that libcurl implemented aspects of the NTLM and Negotiate authentication incorrectly. If an application uses libcurl and the affected mechanisms in a specific way, certain requests to a previously NTLM-authenticated server could appears as sent by the wrong authenticated user. Additionally, the initial set of credentials for HTTP Negotiate-authenticated requests could be reused in subsequent requests, although a different set of credentials was specified. (CVE-2015-3143, CVE-2015-3148)

Red Hat would like to thank the cURL project for reporting these issues.

Bug fixes :

* An out-of-protocol fallback to SSL 3.0 was available with libcurl.
Attackers could abuse the fallback to force downgrade of the SSL version. The fallback has been removed from libcurl. Users requiring this functionality can explicitly enable SSL 3.0 through the libcurl API. (BZ#1154060)

* TLS 1.1 and TLS 1.2 are no longer disabled by default in libcurl.
You can explicitly disable them through the libcurl API. (BZ#1170339)

* FTP operations such as downloading files took a significantly long time to complete. Now, the FTP implementation in libcurl correctly sets blocking direction and estimated timeout for connections, resulting in faster FTP transfers. (BZ#1218272)

Enhancements :

* With the updated packages, it is possible to explicitly enable or disable new Advanced Encryption Standard (AES) cipher suites to be used for the TLS protocol. (BZ#1066065)

* The libcurl library did not implement a non-blocking SSL handshake, which negatively affected performance of applications based on the libcurl multi API. The non-blocking SSL handshake has been implemented in libcurl, and the libcurl multi API now immediately returns the control back to the application whenever it cannot read or write data from or to the underlying network socket. (BZ#1091429)

* The libcurl library used an unnecessarily long blocking delay for actions with no active file descriptors, even for short operations.
Some actions, such as resolving a host name using /etc/hosts, took a long time to complete. The blocking code in libcurl has been modified so that the initial delay is short and gradually increases until an event occurs. (BZ#1130239)

All curl users are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add these enhancements.

Updated file packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The file command is used to identify a particular file according to the type of data the file contains. It can identify many different file types, including Executable and Linkable Format (ELF) binary files, system libraries, RPM packages, and different graphics formats.

Multiple denial of service flaws were found in the way file parsed certain Composite Document Format (CDF) files. A remote attacker could use either of these flaws to crash file, or an application using file, via a specially crafted CDF file. (CVE-2014-0207, CVE-2014-0237, CVE-2014-0238, CVE-2014-3479, CVE-2014-3480, CVE-2014-3487, CVE-2014-3587)

Two flaws were found in the way file processed certain Pascal strings.
A remote attacker could cause file to crash if it was used to identify the type of the attacker-supplied file. (CVE-2014-3478, CVE-2014-9652)

Multiple flaws were found in the file regular expression rules for detecting various files. A remote attacker could use these flaws to cause file to consume an excessive amount of CPU. (CVE-2014-3538)

Multiple flaws were found in the way file parsed Executable and Linkable Format (ELF) files. A remote attacker could use these flaws to cause file to crash, disclose portions of its memory, or consume an excessive amount of system resources. (CVE-2014-3710, CVE-2014-8116, CVE-2014-8117, CVE-2014-9653)

Red Hat would like to thank Thomas Jarosch of Intra2net AG for reporting the CVE-2014-8116 and CVE-2014-8117 issues. The CVE-2014-0207, CVE-2014-0237, CVE-2014-0238, CVE-2014-3478, CVE-2014-3479, CVE-2014-3480, CVE-2014-3487, CVE-2014-3710 issues were discovered by Francisco Alonso of Red Hat Product Security; the CVE-2014-3538 issue was discovered by Jan Kaluza of the Red Hat Web Stack Team

The file packages have been updated to ensure correct operation on Power little endian and ARM 64-bit hardware architectures.
(BZ#1224667, BZ#1224668, BZ#1157850, BZ#1067688).

All file users are advised to upgrade to these updated packages, which contain backported patches to correct these issues.

Updated krb5 packages that fix two security issues, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Kerberos is a network authentication system, which can improve the security of your network by eliminating the insecure practice of sending passwords over the network in unencrypted form. It allows clients and servers to authenticate to each other with the help of a trusted third party, the Kerberos key distribution center (KDC).

It was found that the krb5_read_message() function of MIT Kerberos did not correctly sanitize input, and could create invalid krb5_data objects. A remote, unauthenticated attacker could use this flaw to crash a Kerberos child process via a specially crafted request.
(CVE-2014-5355)

A flaw was found in the OTP kdcpreauth module of MIT kerberos. An unauthenticated remote attacker could use this flaw to bypass the requires_preauth flag on a client principal and obtain a ciphertext encrypted in the principal's long-term key. This ciphertext could be used to conduct an off-line dictionary attack against the user's password. (CVE-2015-2694)

The krb5 packages have been upgraded to upstream version 1.13.2, which provides a number of bug fixes and enhancements over the previous version. (BZ#1203889)

Notably, this update fixes the following bugs :

* Previously, the RADIUS support (libkrad) in krb5 was sending krb5 authentication for Transmission Control Protocol (TCP) transports multiple times, accidentally using a code path intended to be used only for unreliable transport types, for example User Datagram Protocol (UDP) transports. A patch that fixes the problem by disabling manual retries for reliable transports, such as TCP, has been applied, and the correct code path is now used in this situation. (BZ#1251586)

* Attempts to use Kerberos single sign-on (SSO) to access SAP NetWeaver systems sometimes failed. The SAP NetWeaver developer trace displayed the following error message :

No credentials were supplied, or the credentials were unavailable or inaccessible Unable to establish the security context

Querying SSO credential lifetime has been modified to trigger credential acquisition, thus preventing the error from occurring. Now, the user can successfully use Kerberos SSO for accessing SAP NetWeaver systems. (BZ#1252454)

All krb5 users are advised to upgrade to these updated packages, which correct these issues and add these enhancements.

Updated kernel packages that fix multiple security issues, address several hundred bugs, and add numerous enhancements are now available as part of the ongoing support and maintenance of Red Hat Enterprise Linux version 7. This is the second regular update.

Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

* A flaw was found in the way the Linux kernel's file system implementation handled rename operations in which the source was inside and the destination was outside of a bind mount. A privileged user inside a container could use this flaw to escape the bind mount and, potentially, escalate their privileges on the system.
(CVE-2015-2925, Important)

* A race condition flaw was found in the way the Linux kernel's IPC subsystem initialized certain fields in an IPC object structure that were later used for permission checking before inserting the object into a globally visible list. A local, unprivileged user could potentially use this flaw to elevate their privileges on the system.
(CVE-2015-7613, Important)

* It was found that reporting emulation failures to user space could lead to either a local (CVE-2014-7842) or a L2->L1 (CVE-2010-5313) denial of service. In the case of a local denial of service, an attacker must have access to the MMIO area or be able to access an I/O port. (CVE-2010-5313, CVE-2014-7842, Moderate)

* A flaw was found in the way the Linux kernel's KVM subsystem handled non-canonical addresses when emulating instructions that change the RIP (for example, branches or calls). A guest user with access to an I/O or MMIO region could use this flaw to crash the guest.
(CVE-2014-3647, Moderate)

* It was found that the Linux kernel memory resource controller's (memcg) handling of OOM (out of memory) conditions could lead to deadlocks. An attacker could use this flaw to lock up the system.
(CVE-2014-8171, Moderate)

* A race condition flaw was found between the chown and execve system calls. A local, unprivileged user could potentially use this flaw to escalate their privileges on the system. (CVE-2015-3339, Moderate)

* A flaw was discovered in the way the Linux kernel's TTY subsystem handled the tty shutdown phase. A local, unprivileged user could use this flaw to cause a denial of service on the system. (CVE-2015-4170, Moderate)

* A NULL pointer dereference flaw was found in the SCTP implementation. A local user could use this flaw to cause a denial of service on the system by triggering a kernel panic when creating multiple sockets in parallel while the system did not have the SCTP module loaded. (CVE-2015-5283, Moderate)

* A flaw was found in the way the Linux kernel's perf subsystem retrieved userlevel stack traces on PowerPC systems. A local, unprivileged user could use this flaw to cause a denial of service on the system. (CVE-2015-6526, Moderate)

* A flaw was found in the way the Linux kernel's Crypto subsystem handled automatic loading of kernel modules. A local user could use this flaw to load any installed kernel module, and thus increase the attack surface of the running kernel. (CVE-2013-7421, CVE-2014-9644, Low)

* An information leak flaw was found in the way the Linux kernel changed certain segment registers and thread-local storage (TLS) during a context switch. A local, unprivileged user could use this flaw to leak the user space TLS base address of an arbitrary process.
(CVE-2014-9419, Low)

* It was found that the Linux kernel KVM subsystem's sysenter instruction emulation was not sufficient. An unprivileged guest user could use this flaw to escalate their privileges by tricking the hypervisor to emulate a SYSENTER instruction in 16-bit mode, if the guest OS did not initialize the SYSENTER model-specific registers (MSRs). Note: Certified guest operating systems for Red Hat Enterprise Linux with KVM do initialize the SYSENTER MSRs and are thus not vulnerable to this issue when running on a KVM hypervisor.
(CVE-2015-0239, Low)

* A flaw was found in the way the Linux kernel handled the securelevel functionality after performing a kexec operation. A local attacker could use this flaw to bypass the security mechanism of the securelevel/secureboot combination. (CVE-2015-7837, Low)

Updated xfsprogs packages that fix one security issue, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The xfsprogs packages contain a set of commands to use the XFS file system, including the mkfs.xfs command to construct an XFS system.

It was discovered that the xfs_metadump tool of the xfsprogs suite did not fully adhere to the standards of obfuscation described in its man page. In case a user with the necessary privileges used xfs_metadump and relied on the advertised obfuscation, the generated data could contain unexpected traces of potentially sensitive information.
(CVE-2012-2150)

The xfsprogs packages have been upgraded to upstream version 3.2.2, which provides a number of bug fixes and enhancements over the previous version. This release also includes updates present in upstream version 3.2.3, although it omits the mkfs.xfs default disk format change (for metadata checksumming) which is present upstream.
(BZ#1223991)

Users of xfsprogs are advised to upgrade to these updated packages, which fix these bugs and add these enhancements.

Updated libssh2 packages that fix one security issue and two bugs are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The libssh2 packages provide a library that implements the SSH2 protocol.

A flaw was found in the way the kex_agree_methods() function of libssh2 performed a key exchange when negotiating a new SSH session. A man-in-the-middle attacker could use a crafted SSH_MSG_KEXINIT packet to crash a connecting libssh2 client. (CVE-2015-1782)

This update also fixes the following bugs :

* Previously, libssh2 did not correctly adjust the size of the receive window while reading from an SSH channel. This caused downloads over the secure copy (SCP) protocol to consume an excessive amount of memory. A series of upstream patches has been applied on the libssh2 source code to improve handling of the receive window size. Now, SCP downloads work as expected. (BZ#1080459)

* Prior to this update, libssh2 did not properly initialize an internal variable holding the SSH agent file descriptor, which caused the agent destructor to close the standard input file descriptor by mistake. An upstream patch has been applied on libssh2 sources to properly initialize the internal variable. Now, libssh2 closes only the file descriptors it owns. (BZ#1147717)

All libssh2 users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing these updated packages, all running applications using libssh2 must be restarted for this update to take effect.

Updated openldap packages that fix one security issue, several bugs, and add one enhancement are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

OpenLDAP is an open source suite of Lightweight Directory Access Protocol (LDAP) applications and development tools. LDAP is a set of protocols used to access and maintain distributed directory information services over an IP network. The openldap packages contain configuration files, libraries, and documentation for OpenLDAP.

A flaw was found in the way OpenLDAP parsed OpenSSL-style cipher strings. As a result, OpenLDAP could potentially use ciphers that were not intended to be enabled. (CVE-2015-3276)

This issue was discovered by Martin Poole of the Red Hat Software Maintenance Engineering group.

The openldap packages have been upgraded to upstream version 2.4.40, which provides a number of bug fixes and one enhancement over the previous version :

* The ORDERING matching rules have been added to the ppolicy attribute type descriptions.

* The server no longer terminates unexpectedly when processing SRV records.

* Missing objectClass information has been added, which enables the user to modify the front-end configuration by standard means.

(BZ#1147982)

This update also fixes the following bugs :

* Previously, OpenLDAP did not properly handle a number of simultaneous updates. As a consequence, sending a number of parallel update requests to the server could cause a deadlock. With this update, a superfluous locking mechanism causing the deadlock has been removed, thus fixing the bug. (BZ#1125152)

* The httpd service sometimes terminated unexpectedly with a segmentation fault on the libldap library unload. The underlying source code has been modified to prevent a bad memory access error that caused the bug to occur. As a result, httpd no longer crashes in this situation. (BZ#1158005)

* After upgrading the system from Red Hat Enterprise Linux 6 to Red Hat Enterprise Linux 7, symbolic links to certain libraries unexpectedly pointed to locations belonging to the openldap-devel package. If the user uninstalled openldap-devel, the symbolic links were broken and the 'rpm -V openldap' command sometimes produced errors. With this update, the symbolic links no longer get broken in the described situation. If the user downgrades openldap to version 2.4.39-6 or earlier, the symbolic links might break. After such downgrade, it is recommended to verify that the symbolic links did not break. To do this, make sure the yum-plugin-verify package is installed and obtain the target libraries by running the 'rpm -V openldap' or 'yum verify openldap' command. (BZ#1230263)

In addition, this update adds the following enhancement :

* OpenLDAP clients now automatically choose the Network Security Services (NSS) default cipher suites for communication with the server. It is no longer necessary to maintain the default cipher suites manually in the OpenLDAP source code. (BZ#1245279)

All openldap users are advised to upgrade to these updated packages, which correct these issues and add this enhancement.

Updated grep packages that fix one security issue and several bugs are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The grep utility searches through textual input for lines that contain a match to a specified pattern and then prints the matching lines. The GNU grep utilities include grep, egrep, and fgrep.

A heap-based buffer overflow flaw was found in the way grep processed certain pattern and text combinations. An attacker able to trick a user into running grep on specially crafted input could use this flaw to crash grep or, potentially, read from uninitialized memory.
(CVE-2015-1345)

This update also fixes the following bugs :

* Prior to this update, the \w and \W symbols were inconsistently matched to the [:alnum:] character class. Consequently, using regular expressions with '\w' and '\W' could lead to incorrect results. With this update, '\w' is consistently matched to the [_[:alnum:]] character, and '\W' is consistently matched to the [^_[:alnum:]] character. (BZ#1159012)

* Previously, the Perl Compatible Regular Expression (PCRE) matcher (selected by the '-P' parameter in grep) did not work correctly when matching non-UTF-8 text in UTF-8 locales. Consequently, an error message about invalid UTF-8 byte sequence characters was returned. To fix this bug, patches from upstream have been applied to the grep utility. As a result, PCRE now skips non-UTF-8 characters as non-matching text without returning any error message. (BZ#1217080)

All grep users are advised to upgrade to these updated packages, which contain backported patches to correct these issues.

Updated cpio packages that fix one security issue and two bugs are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The cpio packages provide the GNU cpio utility for creating and extracting archives, or copying files from one place to another.

A heap-based buffer overflow flaw was found in cpio's list_file() function. An attacker could provide a specially crafted archive that, when processed by cpio, would crash cpio, or potentially lead to arbitrary code execution. (CVE-2014-9112)

This update fixes the following bugs :

* Previously, during archive creation, cpio internals did not detect a read() system call failure. Based on the premise that the call succeeded, cpio terminated unexpectedly with a segmentation fault without processing further files. The underlying source code has been patched, and an archive is now created successfully. (BZ#1138148)

* Previously, running the cpio command without parameters on Red Hat Enterprise Linux 7 with Russian as the default language resulted in an error message that was not accurate in Russian due to an error in spelling. This has been corrected and the Russian error message is spelled correctly. (BZ#1075513)

All cpio users are advised to upgrade to these updated packages, which contain backported patches to correct these issues.

Updated python packages that fix multiple security issues, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Python is an interpreted, interactive, object-oriented programming language often compared to Tcl, Perl, Scheme, or Java. Python includes modules, classes, exceptions, very high level dynamic data types and dynamic typing. Python supports interfaces to many system calls and libraries, as well as to various windowing systems (X11, Motif, Tk, Mac and MFC).

It was discovered that the Python xmlrpclib module did not restrict the size of gzip-compressed HTTP responses. A malicious XMLRPC server could cause an XMLRPC client using xmlrpclib to consume an excessive amount of memory. (CVE-2013-1753)

It was discovered that multiple Python standard library modules implementing network protocols (such as httplib or smtplib) failed to restrict the sizes of server responses. A malicious server could cause a client using one of the affected modules to consume an excessive amount of memory. (CVE-2013-1752)

It was discovered that the CGIHTTPServer module incorrectly handled URL encoded paths. A remote attacker could use this flaw to execute scripts outside of the cgi-bin directory, or disclose the source code of the scripts in the cgi-bin directory. (CVE-2014-4650)

An integer overflow flaw was found in the way the buffer() function handled its offset and size arguments. An attacker able to control these arguments could use this flaw to disclose portions of the application memory or cause it to crash. (CVE-2014-7185)

A flaw was found in the way the json module handled negative index arguments passed to certain functions (such as raw_decode()). An attacker able to control the index value passed to one of the affected functions could possibly use this flaw to disclose portions of the application memory. (CVE-2014-4616)

The Python standard library HTTP client modules (such as httplib or urllib) did not perform verification of TLS/SSL certificates when connecting to HTTPS servers. A man-in-the-middle attacker could use this flaw to hijack connections and eavesdrop or modify transferred data. (CVE-2014-9365)

Note: The Python standard library was updated to make it possible to enable certificate verification by default. However, for backwards compatibility, verification remains disabled by default. Future updates may change this default. Refer to the Knowledgebase article 2039753 linked to in the References section for further details about this change. (BZ#1219108)

This update also fixes the following bugs :

* Subprocesses used with the Eventlet library or regular threads previously tried to close epoll file descriptors twice, which led to an 'Invalid argument' error. Subprocesses have been fixed to close the file descriptors only once. (BZ#1103452)

* When importing the readline module from a Python script, Python no longer produces erroneous random characters on stdout. (BZ#1189301)

* The cProfile utility has been fixed to print all values that the '-s' option supports when this option is used without a correct value.
(BZ#1237107)

* The load_cert_chain() function now accepts 'None' as a keyfile argument. (BZ#1250611)

In addition, this update adds the following enhancements :

* Security enhancements as described in PEP 466 have been backported to the Python standard library, for example, new features of the ssl module: Server Name Indication (SNI) support, support for new TLSv1.x protocols, new hash algorithms in the hashlib module, and many more.
(BZ#1111461)

* Support for the ssl.PROTOCOL_TLSv1_2 protocol has been added to the ssl library. (BZ#1192015)

* The ssl.SSLSocket.version() method is now available to access information about the version of the SSL protocol used in a connection. (BZ#1259421)

All python users are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add these enhancements.
