Updated libreswan 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.

Libreswan is an implementation of IPsec & IKE for Linux. IPsec is the Internet Protocol Security and uses strong cryptography to provide both authentication and encryption services. These services allow you to build secure tunnels through untrusted networks such as virtual private network (VPN).

A flaw was discovered in the way Libreswan's IKE daemon processed certain IKEv1 payloads. A remote attacker could send specially crafted IKEv1 payloads that, when processed, would lead to a denial of service (daemon crash). (CVE-2015-3204)

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

This update fixes the following bugs :

* Previously, the programs/pluto/state.h and programs/pluto/kernel_netlink.c files had a maximum SELinux context size of 257 and 1024 respectively. These restrictions set by libreswan limited the size of the context that can be exchanged by pluto (the IPSec daemon) when using a Labeled Internet Protocol Security (IPsec).
The SElinux labels for Labeled IPsec have been extended to 4096 bytes and the mentioned restrictions no longer exist. (BZ#1198650)

* On some architectures, the kernel AES_GCM IPsec algorithm did not work properly with acceleration drivers. On those kernels, some acceleration modules are added to the modprobe blacklist. However, Libreswan was ignoring this blacklist, leading to AES_GCM failures.
This update adds support for the module blacklist to the libreswan packages and thus prevents the AES_GCM failures from occurring.
(BZ#1208022)

* An IPv6 issue has been resolved that prevented ipv6-icmp Neighbour Discovery from working properly once an IPsec tunnel is established (and one endpoint reboots). When upgrading, ensure that /etc/ipsec.conf is loading all /etc/ipsec.d/*conf files using the /etc/ipsec.conf 'include' statement, or explicitly include this new configuration file in /etc/ipsec.conf. (BZ#1208023)

* A FIPS self-test prevented libreswan from properly starting in FIPS mode. This bug has been fixed and libreswan now works in FIPS mode as expected. (BZ#1211146)

In addition, this update adds the following enhancements :

* A new option 'seedbits=' has been added to pre-seed the Network Security Services (NSS) pseudo random number generator (PRNG) function with entropy from the /dev/random file on startup. This option is disabled by default. It can be enabled by setting the 'seedbits=' option in the 'config setup' section in the /etc/ipsec.conf file.
(BZ#1198649)

* The build process now runs a Cryptographic Algorithm Validation Program (CAVP) certification test on the Internet Key Exchange version 1 and 2 (IKEv1 and IKEv2) PRF/PRF+ functions. (BZ#1213652)

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

Updated mailman 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.

Mailman is a program used to help manage email discussion lists.

It was found that mailman did not sanitize the list name before passing it to certain MTAs. A local attacker could use this flaw to execute arbitrary code as the user running mailman. (CVE-2015-2775)

This update also fixes the following bugs :

* Previously, it was impossible to configure Mailman in a way that Domain-based Message Authentication, Reporting & Conformance (DMARC) would recognize Sender alignment for Domain Key Identified Mail (DKIM) signatures. Consequently, Mailman list subscribers that belonged to a mail server with a 'reject' policy for DMARC, such as yahoo.com or AOL.com, were unable to receive Mailman forwarded messages from senders residing in any domain that provided DKIM signatures. With this update, domains with a 'reject' DMARC policy are recognized correctly, and Mailman list administrators are able to configure the way these messages are handled. As a result, after a proper configuration, subscribers now correctly receive Mailman forwarded messages in this scenario. (BZ#1229288)

* Previously, the /etc/mailman file had incorrectly set permissions, which in some cases caused removing Mailman lists to fail with a ''NoneType' object has no attribute 'close'' message. With this update, the permissions value for /etc/mailman is correctly set to 2775 instead of 0755, and removing Mailman lists now works as expected. (BZ#1229307)

* Prior to this update, the mailman utility incorrectly installed the tmpfiles configuration in the /etc/tmpfiles.d/ directory. As a consequence, changes made to mailman tmpfiles configuration were overwritten if the mailman packages were reinstalled or updated. The mailman utility now installs the tmpfiles configuration in the /usr/lib/tmpfiles.d/ directory, and changes made to them by the user are preserved on reinstall or update. (BZ#1229306)

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

Updated kernel 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 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.

* It was found that the Linux kernel's implementation of vectored pipe read and write functionality did not take into account the I/O vectors that were already processed when retrying after a failed atomic access operation, potentially resulting in memory corruption due to an I/O vector array overrun. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2015-1805, Important)

* A race condition flaw was found in the way the Linux kernel keys management subsystem performed key garbage collection. A local attacker could attempt accessing a key while it was being garbage collected, which would cause the system to crash. (CVE-2014-9529, Moderate)

* A flaw was found in the way the Linux kernel's 32-bit emulation implementation handled forking or closing of a task with an 'int80' entry. A local user could potentially use this flaw to escalate their privileges on the system. (CVE-2015-2830, Low)

* It was found that the Linux kernel's ISO file system implementation did not correctly limit the traversal of Rock Ridge extension Continuation Entries (CE). An attacker with physical access to the system could use this flaw to trigger an infinite loop in the kernel, resulting in a denial of service. (CVE-2014-9420, Low)

* An information leak flaw was found in the way the Linux kernel's ISO9660 file system implementation accessed data on an ISO9660 image with RockRidge Extension Reference (ER) records. An attacker with physical access to the system could use this flaw to disclose up to 255 bytes of kernel memory. (CVE-2014-9584, Low)

* A flaw was found in the way the nft_flush_table() function of the Linux kernel's netfilter tables implementation flushed rules that were referencing deleted chains. A local user who has the CAP_NET_ADMIN capability could use this flaw to crash the system. (CVE-2015-1573, Low)

* An integer overflow flaw was found in the way the Linux kernel randomized the stack for processes on certain 64-bit architecture systems, such as x86-64, causing the stack entropy to be reduced by four. (CVE-2015-1593, Low)

Red Hat would like to thank Carl Henrik Lunde for reporting CVE-2014-9420 and CVE-2014-9584. The security impact of the CVE-2015-1805 issue was discovered by Red Hat.

(CVE-2015-2301, CVE-2015-2783, CVE-2015-3307, CVE-2015-3329, CVE-2015-4021)

Multiple flaws were found in PHP's File Information (fileinfo) extension. A remote attacker could cause a PHP application to crash if it used fileinfo to identify type of attacker supplied files.
(CVE-2014-9652, CVE-2015-4604, CVE-2015-4605)

A heap buffer overflow flaw was found in the enchant_broker_request_dict() function of PHP's enchant extension. An attacker able to make a PHP application enchant dictionaries could possibly cause it to crash. (CVE-2014-9705)

A buffer over-read flaw was found in the GD library used by the PHP gd extension. A specially crafted GIF file could cause a PHP application using the imagecreatefromgif() function to crash. (CVE-2014-9709)

This update also fixes the following bugs :

* The libgmp library in some cases terminated unexpectedly with a segmentation fault when being used with other libraries that use the GMP memory management. With this update, PHP no longer changes libgmp memory allocators, which prevents the described crash from occurring.
(BZ#1212305)

* When using the Open Database Connectivity (ODBC) API, the PHP process in some cases terminated unexpectedly with a segmentation fault. The underlying code has been adjusted to prevent this crash.
(BZ#1212299)

* Previously, running PHP on a big-endian system sometimes led to memory corruption in the fileinfo module. This update adjusts the behavior of the PHP pointer so that it can be freed without causing memory corruption. (BZ#1212298)

All php users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, the httpd daemon must be restarted for the update to take effect.

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 wpa_supplicant package contains an 802.1X Supplicant with support for WEP, WPA, WPA2 (IEEE 802.11i / RSN), and various EAP authentication methods. It implements key negotiation with a WPA Authenticator for client stations and controls the roaming and IEEE 802.11 authentication and association of the WLAN driver.

A buffer overflow flaw was found in the way wpa_supplicant handled SSID information in the Wi-Fi Direct / P2P management frames. A specially crafted frame could allow an attacker within Wi-Fi radio range to cause wpa_supplicant to crash or, possibly, execute arbitrary code. (CVE-2015-1863)

An integer underflow flaw, leading to a buffer over-read, was found in the way wpa_supplicant handled WMM Action frames. A specially crafted frame could possibly allow an attacker within Wi-Fi radio range to cause wpa_supplicant to crash. (CVE-2015-4142)

Red Hat would like to thank Jouni Malinen of the wpa_supplicant upstream for reporting the CVE-2015-1863 issue. Upstream acknowledges Alibaba security team as the original reporter.

This update also adds the following enhancement :

* Prior to this update, wpa_supplicant did not provide a way to require the host name to be listed in an X.509 certificate's Common Name or Subject Alternative Name, and only allowed host name suffix or subject substring checks. This update introduces a new configuration directive, 'domain_match', which adds a full host name check.
(BZ#1178263)

All wpa_supplicant users are advised to upgrade to this updated package, which contains backported patches to correct these issues and add this enhancement. After installing this update, the wpa_supplicant service will be restarted automatically.

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.

It was found that ABRT was vulnerable to multiple race condition and symbolic link flaws. A local attacker could use these flaws to potentially escalate their privileges on the system. (CVE-2015-3315)

It was discovered that the kernel-invoked coredump processor provided by ABRT wrote core dumps to files owned by other system users. This could result in information disclosure if an application crashed while its current directory was a directory writable to by other users (such as /tmp). (CVE-2015-3142)

It was discovered that the default event handling scripts installed by ABRT did not handle symbolic links correctly. A local attacker with write access to an ABRT problem directory could use this flaw to escalate their privileges. (CVE-2015-1869)

It was found that the ABRT event scripts created a user-readable copy of an sosreport file in ABRT problem directories, and included excerpts of /var/log/messages selected by the user-controlled process name, leading to an information disclosure. (CVE-2015-1870)

It was discovered that, when moving problem reports between certain directories, abrt-handle-upload did not verify that the new problem directory had appropriate permissions and did not contain symbolic links. An attacker able to create a crafted problem report could use this flaw to expose other parts of ABRT to attack, or to overwrite arbitrary files on the system. (CVE-2015-3147)

Multiple directory traversal flaws were found in the abrt-dbus D-Bus service. A local attacker could use these flaws to read and write arbitrary files as the root user. (CVE-2015-3151)

It was discovered that the abrt-dbus D-Bus service did not properly check the validity of the problem directory argument in the ChownProblemDir, DeleteElement, and DeleteProblem methods. A local attacker could use this flaw to take ownership of arbitrary files and directories, or to delete files and directories as the root user.
(CVE-2015-3150)

It was discovered that the abrt-action-install-debuginfo-to-abrt-cache helper program did not properly filter the process environment before invoking abrt-action-install-debuginfo. A local attacker could use this flaw to escalate their privileges on the system. (CVE-2015-3159)

All users of abrt are advised to upgrade to these updated packages, which correct these issues.

KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on AMD64 and Intel 64 systems. The qemu-kvm package provides the user-space component for running virtual machines using KVM.

A flaw was found in the way QEMU's AMD PCnet Ethernet emulation handled multi-TMD packets with a length above 4096 bytes. A privileged guest user in a guest with an AMD PCNet ethernet card enabled could potentially use this flaw to execute arbitrary code on the host with the privileges of the hosting QEMU process. (CVE-2015-3209)

Red Hat would like to thank Matt Tait of Google's Project Zero security team for reporting this issue.

All qemu-kvm users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. After installing this update, shut down all running virtual machines. Once all virtual machines have shut down, start them again for this update to take effect.

A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2015-1805, Important)

* A buffer overflow flaw was found in the way the Linux kernel's Intel AES-NI instructions optimized version of the RFC4106 GCM mode decryption functionality handled fragmented packets. A remote attacker could use this flaw to crash, or potentially escalate their privileges on, a system over a connection with an active AES-GCM mode IPSec security association. (CVE-2015-3331, Important)

* 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's ISO file system implementation did not correctly limit the traversal of Rock Ridge extension Continuation Entries (CE). An attacker with physical access to the system could use this flaw to trigger an infinite loop in the kernel, resulting in a denial of service. (CVE-2014-9420, Low)

* An information leak flaw was found in the way the Linux kernel's Virtual Dynamic Shared Object (vDSO) implementation performed address randomization. A local, unprivileged user could use this flaw to leak kernel memory addresses to user-space. (CVE-2014-9585, Low)

Red Hat would like to thank Carl Henrik Lunde for reporting CVE-2014-9420. The security impact of the CVE-2015-1805 issue was discovered by Red Hat.

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.

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 flaw was found in the way the TLS protocol composes the Diffie-Hellman (DH) key exchange. A man-in-the-middle attacker could use this flaw to force the use of weak 512 bit export-grade keys during the key exchange, allowing them do decrypt all traffic.
(CVE-2015-4000)

Note: This update forces the TLS/SSL client implementation in OpenSSL to reject DH key sizes below 768 bits, which prevents sessions to be downgraded to export-grade keys. Future updates may raise this limit to 1024 bits.

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

Updated kernel packages that fix one security issue and several bugs are now available for Red Hat Enterprise Linux 5.

The security impact of this issue was discovered by Red Hat.

This update fixes the following bugs :

* Due to a bug in the lpfc_device_reset_handler() function, a scsi command timeout could lead to a system crash. With this update, lpfc_device_reset_handler recovers storage without crashing.
(BZ#1070964)

* Due to the code decrementing the reclaim_in_progress counter without having incremented it first, severe spinlock contention occurred in the shrink_zone() function even though the vm.max_reclaims_in_progress feature was set to 1. This update provides a patch fixing the underlying source code, and spinlock contention no longer occurs in this scenario. (BZ#1164105)

* A TCP socket using SACK that had a retransmission but recovered from it, failed to reset the retransmission timestamp. As a consequence, on certain connections, if a packet had to be re-transmitted, the retrans_stamp variable was only cleared when the next acked packet was received. This could lead to an early abortion of the TCP connection if this next packet also got lost. With this update, the socket clears retrans_stamp when the recovery is completed, thus fixing the bug.
(BZ#1205521)

* Previously, the signal delivery paths did not clear the TS_USEDFPU flag, which could cause problems in the switch_to() function and lead to floating-point unit (FPU) corruption. With this update, TS_USEDFPU is cleared as expected, and FPU is no longer under threat of corruption. (BZ#1193505)

* A race condition in the exit_sem() function previously caused the semaphore undo list corruption. As a consequence, a kernel crash could occur. The corruption in the semaphore undo list has been fixed, and the kernel no longer crashes in this situation. (BZ#1124574)

* Previously, when running the 'virsh blockresize [Device] [Newsize]' command to resize the disk, the new size was not reflected in a Red Hat Enterprise Linux 5 Virtual Machine (VM). With this update, the new size is now reflected online immediately in a Red Hat Enterprise Linux 5 VM so it is no longer necessary to reboot the VM to see the new disk size. (BZ#1200855)

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.

An updated thunderbird package that fixes multiple security issues is now available for Red Hat Enterprise Linux 5, 6, and 7.

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.

Mozilla Thunderbird is a standalone mail and newsgroup client.

Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2015-2708, CVE-2015-2710, CVE-2015-2713)

A heap-based buffer overflow flaw was found in the way Thunderbird processed compressed XML data. An attacker could create specially crafted compressed XML content that, when processed by Thunderbird, could cause it to crash or execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2015-2716)

Note: All of the above issues cannot be exploited by a specially crafted HTML mail message as JavaScript is disabled by default for mail messages. They could be exploited another way in Thunderbird, for example, when viewing the full remote content of an RSS feed.

Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Jesse Ruderman, Mats Palmgren, Byron Campen, Steve Fink, Atte Kettunen, Scott Bell, and Ucha Gobejishvili as the original reporters of these issues.

For technical details regarding these flaws, refer to the Mozilla security advisories for Thunderbird 31.7. You can find a link to the Mozilla advisories in the References section of this erratum.

All Thunderbird users should upgrade to this updated package, which contains Thunderbird version 31.7, which corrects these issues. After installing the update, Thunderbird must be restarted for the changes to take effect.

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

* A buffer overflow flaw was found in the way the Linux kernel's Intel AES-NI instructions optimized version of the RFC4106 GCM mode decryption functionality handled fragmented packets. A remote attacker could use this flaw to crash, or potentially escalate their privileges on, a system over a connection with an active AEC-GCM mode IPSec security association. (CVE-2015-3331, Important)

This update also fixes the following bugs :

* Previously, the kernel audit subsystem did not correctly track file path names which could lead to empty, or '(null)' path names in the PATH audit records. This update fixes the bug by correctly tracking file path names and displaying the names in the audit PATH records.
(BZ#1197746)

* Due to a change in the internal representation of field types, AUDIT_LOGINUID set to -1 (4294967295) by the audit API was asymmetrically converted to an AUDIT_LOGINUID_SET field with a value of 0, unrecognized by an older audit API. To fix this bug, the kernel takes note about the way the rule has been formulated and reports the rule in the originally given form. As a result, older versions of audit provide a report as expected, in the AUDIT_LOGINUID field type form, whereas the newer versions can migrate to the new AUDIT_LOGINUID_SET filed type. (BZ#1197748)

* The GFS2 file system 'Splice Read' operation, which is used for the sendfile() function, was not properly allocating a required multi-block reservation structure in memory. Consequently, when the GFS2 block allocator was called to assign blocks of data, it attempted to dereference the structure, which resulted in a kernel panic. With this update, 'Splice read' operation properly allocates the necessary reservation structure in memory prior to calling the block allocator, and sendfile() thus works properly for GFS2. (BZ#1201256)

* Moving an Open vSwitch (OVS) internal vport to a different net name space and subsequently deleting that name space led to a kernel panic.
This bug has been fixed by removing the OVS internal vport at net name space deletion. (BZ#1202357)

* Previously, the kernel audit subsystem was not correctly handling file and directory moves, leading to audit records that did not match the audit file watches. This fix correctly handles moves such that the audit file watches work correctly. (BZ#1202358)

* Due to a regression, the crypto adapter could not be set online. A patch has been provided that fixes the device registration process so that the device can be used also before the registration process is completed, thus fixing this bug. (BZ#1205300)

* Due to incorrect calculation for entropy during the entropy addition, the amount of entropy in the /dev/random file could be overestimated. The formula for the entropy addition has been changed, thus fixing this bug. (BZ#1211288)

* Previously, the ansi_cprng and drbg utilities did not obey the call convention and returned the positive value on success instead of the correct value of zero. Consequently, Internet Protocol Security (IPsec) terminated unexpectedly when ansi_cprng or drbg were used.
With this update, ansi_cprng and drbg have been changed to return zero on success, and IPsec now functions correctly. (BZ#1211487)

* Due to a failure to clear the timestamp flag when reusing a tx descriptor in the mlx4_en driver, programs that did not request a hardware timestamp packet on their sent data received it anyway, resulting in unexpected behavior in certain applications. With this update, when reusing the tx descriptor in the mlx4_en driver in the aforementioned situation, the hardware timestamp flag is cleared, and applications now behave as expected. (BZ#1209240)

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.

Updated tomcat6 packages that fix one security issue and one bug are now available for Red Hat Enterprise Linux 6.

Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages (JSP) technologies.

It was discovered that the ChunkedInputFilter in Tomcat did not fail subsequent attempts to read input after malformed chunked encoding was detected. A remote attacker could possibly use this flaw to make Tomcat process part of the request body as new request, or cause a denial of service. (CVE-2014-0227)

This update also fixes the following bug :

* Before this update, the tomcat6 init script did not try to kill the tomcat process if an attempt to stop it was unsuccessful, which would prevent tomcat from restarting properly. The init script was modified to correct this issue. (BZ#1207048)

All Tomcat 6 users are advised to upgrade to these updated packages, which correct these issues. Tomcat must be restarted for this update to take effect.

The pcs packages provide a command-line tool and a web UI to configure and manage the Pacemaker and Corosync tools.

It was found that the pcs daemon did not sign cookies containing session data that were sent to clients connecting via the pcsd web UI.
A remote attacker could use this flaw to forge cookies and bypass authorization checks, possibly gaining elevated privileges in the pcsd web UI. Note: the pcsd web UI is not enabled by default.
(CVE-2015-1848)

This issue was discovered by Tomas Jelinek of Red Hat.

This update also fixes the following bug :

* When the IPv6 protocol was disabled on a system, starting the pcsd daemon on this system previously failed. This update adds the ability for pcsd to fall back to IPv4 when IPv6 is not available. As a result, pcsd starts properly and uses IPv4 if IPv6 is disabled. (BZ#1212115)

All pcs users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, the pcsd daemon will be restarted automatically.

Updated kexec-tools packages that fix one security issue, one bug, 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 kexec-tools packages contain the /sbin/kexec binary and utilities that together form the user-space component of the kernel's kexec feature. The /sbin/kexec binary facilitates a new kernel to boot using the kernel's kexec feature either on a normal or a panic reboot. The kexec fastboot mechanism allows booting a Linux kernel from the context of an already running kernel.

It was found that the module-setup.sh script provided by kexec-tools created temporary files in an insecure way. A malicious, local user could use this flaw to conduct a symbolic link attack, allowing them to overwrite the contents of arbitrary files. (CVE-2015-0267)

This issue was discovered by Harald Hoyer of Red Hat.

This update also fixes the following bug :

* On Red Hat Enterprise Linux Atomic Host systems, the kdump tool previously saved kernel crash dumps in the /sysroot/crash file instead of the /var/crash file. The parsing error that caused this problem has been fixed, and the kernel crash dumps are now correctly saved in /var/crash. (BZ#1206464)

In addition, this update adds the following enhancement :

* The makedumpfile command now supports the new sadump format that can represent more than 16 TB of physical memory space. This allows users of makedumpfile to read dump files over 16 TB, generated by sadump on certain upcoming server models. (BZ#1208753)

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

Updated tomcat 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 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.

It was found that the pcs daemon did not sign cookies containing session data that were sent to clients connecting via the pcsd web UI.
A remote attacker could use this flaw to forge cookies and bypass authorization checks, possibly gaining elevated privileges in the pcsd web UI. (CVE-2015-1848)

This issue was discovered by Tomas Jelinek of Red Hat.

This update also fixes the following bug :

* Previously, the Corosync tool allowed the two_node option and the auto_tie_breaker option to exist in the corosync.conf file at the same time. As a consequence, if both options were included, auto_tie_breaker was silently ignored and the two_node fence race decided which node would survive in the event of a communication break. With this update, the pcs daemon has been fixed so that it does not produce corosync.conf files with both two_node and auto_tie_breaker included. In addition, if both two_node and auto_tie_breaker are detected in corosync.conf, Corosync issues a message at start-up and disables two_node mode. As a result, auto_tie_breaker effectively overrides two_node mode if both options are specified. (BZ#1205848)

All pcs users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, the pcsd daemon will be restarted automatically.

This issue was found by Paolo Bonzini of Red Hat.

This update also fixes the following bug :

* Previously, the effective downtime during the last phase of a live migration would sometimes be much higher than the maximum downtime specified by 'migration_downtime' in vdsm.conf. This problem has been corrected. The value of 'migration_downtime' is now honored and the migration is aborted if the downtime cannot be achieved. (BZ#1142756)

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

* A flaw was found in the way seunshare, a utility for running executables under a different security context, used the capng_lock functionality of the libcap-ng library. The subsequent invocation of suid root binaries that relied on the fact that the setuid() system call, among others, also sets the saved set-user-ID when dropping the binaries' process privileges, could allow a local, unprivileged user to potentially escalate their privileges on the system. Note: the fix for this issue is the kernel part of the overall fix, and introduces the PR_SET_NO_NEW_PRIVS functionality and the related SELinux exec transitions support. (CVE-2014-3215, Important)

* A use-after-free flaw was found in the way the Linux kernel's SCTP implementation handled authentication key reference counting during INIT collisions. A remote attacker could use this flaw to crash the system or, potentially, escalate their privileges on the system.
(CVE-2015-1421, Important)

* It was found that the Linux kernel's KVM implementation did not ensure that the host CR4 control register value remained unchanged across VM entries on the same virtual CPU. A local, unprivileged user could use this flaw to cause a denial of service on the system.
(CVE-2014-3690, Moderate)

* An out-of-bounds memory access flaw was found in the syscall tracing functionality of the Linux kernel's perf subsystem. A local, unprivileged user could use this flaw to crash the system.
(CVE-2014-7825, Moderate)

* An out-of-bounds memory access flaw was found in the syscall tracing functionality of the Linux kernel's ftrace subsystem. On a system with ftrace syscall tracing enabled, a local, unprivileged user could use this flaw to crash the system, or escalate their privileges.
(CVE-2014-7826, 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 able to continuously spawn new processes within a single memory-constrained cgroup during an OOM event could use this flaw to lock up the system. (CVE-2014-8171, Moderate)

* A race condition flaw was found in the way the Linux kernel keys management subsystem performed key garbage collection. A local attacker could attempt accessing a key while it was being garbage collected, which would cause the system to crash. (CVE-2014-9529, Moderate)

* A stack-based buffer overflow flaw was found in the TechnoTrend/Hauppauge DEC USB device driver. A local user with write access to the corresponding device could use this flaw to crash the kernel or, potentially, elevate their privileges on the system.
(CVE-2014-8884, Low)

* An information leak flaw was found in the way the Linux kernel's ISO9660 file system implementation accessed data on an ISO9660 image with RockRidge Extension Reference (ER) records. An attacker with physical access to the system could use this flaw to disclose up to 255 bytes of kernel memory. (CVE-2014-9584, Low)

Red Hat would like to thank Andy Lutomirski for reporting CVE-2014-3215 and CVE-2014-3690, Robert Swiecki for reporting CVE-2014-7825 and CVE-2014-7826, and Carl Henrik Lunde for reporting CVE-2014-9584. The CVE-2015-1421 issue was discovered by Sun Baoliang of Red Hat.

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.

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)

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)

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

This update also fixes the following bug :

* Previously, the nscd daemon did not properly reload modified data when the user edited monitored nscd configuration files. As a consequence, nscd returned stale data to system processes. This update adds a system of inotify-based monitoring and stat-based backup monitoring for nscd configuration files. As a result, nscd now detects changes to its configuration files and reloads the data properly, which prevents it from returning stale data. (BZ#1194149)

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

Kerberos is a networked authentication system which allows clients and servers to authenticate to each other with the help of a trusted third party, the Kerberos KDC.

The following security issues are fixed with this release :

A use-after-free flaw was found in the way the MIT Kerberos libgssapi_krb5 library processed valid context deletion tokens. An attacker able to make an application using the GSS-API library (libgssapi) could call the gss_process_context_token() function and use this flaw to crash that application. (CVE-2014-5352)

If kadmind were used with an LDAP back end for the KDC database, a remote, authenticated attacker who has the permissions to set the password policy could crash kadmind by attempting to use a named ticket policy object as a password policy for a principal.
(CVE-2014-5353)

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 double-free flaw was found in the way MIT Kerberos handled invalid External Data Representation (XDR) data. An authenticated user could use this flaw to crash the MIT Kerberos administration server (kadmind), or other applications using Kerberos libraries, via specially crafted XDR packets. (CVE-2014-9421)

It was found that the MIT Kerberos administration server (kadmind) incorrectly accepted certain authentication requests for two-component server principal names. A remote attacker able to acquire a key with a particularly named principal (such as 'kad/x') could use this flaw to impersonate any user to kadmind, and perform administrative actions as that user. (CVE-2014-9422)

Red Hat would like to thank the MIT Kerberos project for reporting CVE-2014-5352, CVE-2014-9421, and CVE-2014-9422. The MIT Kerberos project acknowledges Nico Williams for assisting with the analysis of CVE-2014-5352.

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.

* It was found that the Linux kernel's Infiniband subsystem did not properly sanitize input parameters while registering memory regions from user space via the (u)verbs API. A local user with access to a /dev/infiniband/uverbsX device could use this flaw to crash the system or, potentially, escalate their privileges on the system.
(CVE-2014-8159, Important)

* An insufficient bound checking flaw was found in the Xen hypervisor's implementation of acceleration support for the 'REP MOVS' instructions. A privileged HVM guest user could potentially use this flaw to crash the host. (CVE-2014-8867, Important)

Red Hat would like to thank Mellanox for reporting CVE-2014-8159, and the Xen project for reporting CVE-2014-8867.

This update also fixes the following bugs :

* Under memory pressure, cached data was previously flushed to the backing server using the PID of the thread responsible for flushing the data in the Server Message Block (SMB) headers instead of the PID of the thread which actually wrote the data. As a consequence, when a file was locked by the writing thread prior to writing, the server considered writes by the thread flushing the pagecache as being a separate process from writing to a locked file, and thus rejected the writes. In addition, the data to be written was discarded. This update ensures that the correct PID is sent to the server, and data corruption is avoided when data is being written from a client under memory pressure. (BZ#1169304)

* This update adds support for new cryptographic hardware in toleration mode for IBM System z. (BZ#1182522)

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.

Its administration tools allow an administrator to quickly install, set up, and administer a group of domain controllers to meet the authentication and identity management requirements of large-scale Linux and UNIX deployments.

The ipa component provides centrally managed Identity, Policy, and Audit. The slapi-nis component provides NIS Server and Schema Compatibility plug-ins for Directory Server.

It was discovered that the IPA extdom Directory Server plug-in did not correctly perform memory reallocation when handling user account information. A request for a list of groups for a user that belongs to a large number of groups would cause a Directory Server to crash.
(CVE-2015-1827)

It was discovered that the slapi-nis Directory Server plug-in did not correctly perform memory reallocation when handling user account information. A request for information about a group with many members, or a request for a user that belongs to a large number of groups, would cause a Directory Server to enter an infinite loop and consume an excessive amount of CPU time. (CVE-2015-0283)

These issues were discovered by Sumit Bose of Red Hat.

This update fixes the following bugs :

* Previously, users of IdM were not properly granted the default permission to read the 'facsimiletelephonenumber' user attribute. This update adds 'facsimiletelephonenumber' to the Access Control Instruction (ACI) for user data, which makes the attribute readable to authenticated users as expected. (BZ#1198430)

* Prior to this update, when a DNS zone was saved in an LDAP database without a dot character (.) at the end, internal DNS commands and operations, such as dnsrecord-* or dnszone-*, failed. With this update, DNS commands always supply the DNS zone with a dot character at the end, which prevents the described problem. (BZ#1198431)

* After a full-server IdM restore operation, the restored server in some cases contained invalid data. In addition, if the restored server was used to reinitialize a replica, the replica then contained invalid data as well. To fix this problem, the IdM API is now created correctly during the restore operation, and *.ldif files are not skipped during the removal of RUV data. As a result, the restored server and its replica no longer contain invalid data. (BZ#1199060)

* Previously, a deadlock in some cases occurred during an IdM upgrade, which could cause the IdM server to become unresponsive. With this update, the Schema Compatibility plug-in has been adjusted not to parse the subtree that contains the configuration of the DNA plug-in, which prevents this deadlock from triggering. (BZ#1199128)

* When using the extdom plug-in of IdM to handle large groups, user lookups and group lookups previously failed due to insufficient buffer size. With this update, the getgrgid_r() call gradually increases the buffer length if needed, and the described failure of extdom thus no longer occurs. (BZ#1203204)

Users of ipa and slapi-nis are advised to upgrade to these updated packages, which correct these issues.

A local user with access to a /dev/infiniband/uverbsX device could use this flaw to crash the system or, potentially, escalate their privileges on the system.
(CVE-2014-8159, Important)

* A use-after-free flaw was found in the way the Linux kernel's SCTP implementation handled authentication key reference counting during INIT collisions. A remote attacker could use this flaw to crash the system or, potentially, escalate their privileges on the system.
(CVE-2015-1421, Important)

Red Hat would like to thank Mellanox for reporting the CVE-2014-8159 issue. The CVE-2015-1421 issue was discovered by Sun Baoliang of Red Hat.

This update also fixes the following bugs :

* In certain systems with multiple CPUs, when a crash was triggered on one CPU with an interrupt handler and this CPU sent Non-Maskable Interrupt (NMI) to another CPU, and, at the same time, ioapic_lock had already been acquired, a deadlock occurred in ioapic_lock. As a consequence, the kdump service could become unresponsive. This bug has been fixed and kdump now works as expected. (BZ#1197742)

* On Lenovo X1 Carbon 3rd Gen, X250, and T550 laptops, the thinkpad_acpi module was not properly loaded, and thus the function keys and radio switches did not work. This update applies a new string pattern of BIOS version, which fixes this bug, and function keys and radio switches now work as intended. (BZ#1197743)

* During a heavy file system load involving many worker threads, all worker threads in the pool became blocked on a resource, and no manager thread existed to create more workers. As a consequence, the running processes became unresponsive. With this update, the logic around manager creation has been changed to assure that the last worker thread becomes a manager thread and does not start executing work items. Now, a manager thread exists, spawns new workers as needed, and processes no longer hang. (BZ#1197744)

* If a thin-pool's metadata enters read-only or fail mode, for example, due to thin-pool running out of metadata or data space, any attempt to make metadata changes such as creating a thin device or snapshot thin device should error out cleanly. However, previously, the kernel code returned verbose and alarming error messages to the user. With this update, due to early trapping of attempt to make metadata changes, informative errors are displayed, no longer unnecessarily alarming the user. (BZ#1197745)

* When running Red Hat Enterprise Linux as a guest on Microsoft Hyper-V hypervisor, the storvsc module did not return the correct error code for the upper level Small Computer System Interface (SCSI) subsystem. As a consequence, a SCSI command failed and storvsc did not handle such a failure properly under some conditions, for example, when RAID devices were created on top of storvsc devices. An upstream patch has been applied to fix this bug, and storvsc now returns the correct error code in the described situation. (BZ#1197749)

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.

An authenticated database user could possibly obtain the results of a query they did not have privileges to execute by observing the constraint violation error messages produced when the query was executed. (CVE-2014-8161)

A buffer overflow flaw was found in the way PostgreSQL handled certain numeric formatting. An authenticated database user could use a specially crafted timestamp formatting template to cause PostgreSQL to crash or, under certain conditions, execute arbitrary code with the permissions of the user running PostgreSQL. (CVE-2015-0241)

A stack-buffer overflow flaw was found in PostgreSQL's pgcrypto module. An authenticated database user could use this flaw to cause PostgreSQL to crash or, potentially, execute arbitrary code with the permissions of the user running PostgreSQL. (CVE-2015-0243)

A flaw was found in the way PostgreSQL handled certain errors that were generated during protocol synchronization. An authenticated database user could use this flaw to inject queries into an existing connection. (CVE-2015-0244)

  - An integer underflow flaw, leading to a buffer overflow,     was found in the way OpenSSL decoded malformed     Base64-encoded inputs. An attacker able to make an     application using OpenSSL decode a specially crafted     Base64-encoded input (such as a PEM file) could use this     flaw to cause the application to crash. Note: this flaw     is not exploitable via the TLS/SSL protocol because the     data being transferred is not Base64-encoded.
    (CVE-2015-0292)

  - A denial of service flaw was found in the way OpenSSL     handled SSLv2 handshake messages. A remote attacker     could use this flaw to cause a TLS/SSL server using     OpenSSL to exit on a failed assertion if it had both     the SSLv2 protocol and EXPORT-grade cipher suites     enabled. (CVE-2015-0293)

  - A use-after-free flaw was found in the way OpenSSL     imported malformed Elliptic Curve private keys. A     specially crafted key file could cause an application     using OpenSSL to crash when imported. (CVE-2015-0209)

  - An out-of-bounds write flaw was found in the way OpenSSL     reused certain ASN.1 structures. A remote attacker could     possibly use a specially crafted ASN.1 structure that,     when parsed by an application, would cause that     application to crash. (CVE-2015-0287)

  - A NULL pointer dereference flaw was found in OpenSSL's     X.509 certificate handling implementation. A specially     crafted X.509 certificate could cause an application     using OpenSSL to crash if the application attempted to     convert the certificate to a certificate request.
    (CVE-2015-0288)

  - A NULL pointer dereference was found in the way OpenSSL     handled certain PKCS#7 inputs. An attacker able to make     an application using OpenSSL verify, decrypt, or parse a     specially crafted PKCS#7 input could cause that     application to crash. TLS/SSL clients and servers using     OpenSSL were not affected by this flaw. (CVE-2015-0289)

An updated thunderbird package that fixes multiple security issues is now available for Red Hat Enterprise Linux 7.

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.

Mozilla Thunderbird is a standalone mail and newsgroup client.

Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2015-0836, CVE-2015-0831, CVE-2015-0827)

An information leak flaw was found in the way Thunderbird implemented autocomplete forms. An attacker able to trick a user into specifying a local file in the form could use this flaw to access the contents of that file. (CVE-2015-0822)

Note: All of the above issues cannot be exploited by a specially crafted HTML mail message as JavaScript is disabled by default for mail messages. They could be exploited another way in Thunderbird, for example, when viewing the full remote content of an RSS feed.

Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Carsten Book, Christoph Diehl, Gary Kwong, Jan de Mooij, Liz Henry, Byron Campen, Tom Schuster, Ryan VanderMeulen, Paul Bandha, Abhishek Arya, and Armin Razmdjou as the original reporters of these issues.

For technical details regarding these flaws, refer to the Mozilla security advisories for Thunderbird 31.5.0. You can find a link to the Mozilla advisories in the References section of this erratum.

All Thunderbird users should upgrade to this updated package, which contains Thunderbird version 31.5.0, which corrects these issues.
After installing the update, Thunderbird must be restarted for the changes to take effect.

Updated unzip packages that fix multiple security issues are now available for Red Hat Enterprise Linux 6 and 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 unzip utility is used to list, test, or extract files from a zip archive.

A buffer overflow was found in the way unzip uncompressed certain extra fields of a file. A specially crafted Zip archive could cause unzip to crash or, possibly, execute arbitrary code when the archive was tested with unzip's '-t' option. (CVE-2014-9636)

A buffer overflow flaw was found in the way unzip computed the CRC32 checksum of certain extra fields of a file. A specially crafted Zip archive could cause unzip to crash when the archive was tested with unzip's '-t' option. (CVE-2014-8139)

An integer underflow flaw, leading to a buffer overflow, was found in the way unzip uncompressed certain extra fields of a file. A specially crafted Zip archive could cause unzip to crash when the archive was tested with unzip's '-t' option. (CVE-2014-8140)

A buffer overflow flaw was found in the way unzip handled Zip64 files.
A specially crafted Zip archive could possibly cause unzip to crash when the archive was uncompressed. (CVE-2014-8141)

Red Hat would like to thank oCERT for reporting the CVE-2014-8139, CVE-2014-8140, and CVE-2014-8141 issues. oCERT acknowledges Michele Spagnuolo of the Google Security Team as the original reporter of these issues.
