An updated sqlite package that fixes one security issue is now available for Red Hat Enterprise Linux 6.

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.

SQLite is a C library that implements a SQL database engine. A large subset of SQL92 is supported. A complete database is stored in a single disk file. The API is designed for convenience and ease of use.
Applications that link against SQLite can enjoy the power and flexibility of a SQL database without the administrative hassles of supporting a separate database server.

It was found that SQLite's sqlite3VXPrintf() function did not properly handle precision and width values during floating-point conversions. A local attacker could submit a specially crafted SELECT statement that would crash the SQLite process, or have other unspecified impacts.
(CVE-2015-3416)

All sqlite users are advised to upgrade to this updated package, which contains a backported patch to correct this issue.

Subversion (SVN) is a concurrent version control system which enables one or more users to collaborate in developing and maintaining a hierarchy of files and directories while keeping a history of all changes. The mod_dav_svn module is used with the Apache HTTP Server to allow access to Subversion repositories via HTTP.

An assertion failure flaw was found in the way the SVN server processed certain requests with dynamically evaluated revision numbers. A remote attacker could use this flaw to cause the SVN server (both svnserve and httpd with the mod_dav_svn module) to crash.
(CVE-2015-0248)

It was found that the mod_dav_svn module did not properly validate the svn:author property of certain requests. An attacker able to create new revisions could use this flaw to spoof the svn:author property.
(CVE-2015-0251)

It was found that when an SVN server (both svnserve and httpd with the mod_dav_svn module) searched the history of a file or a directory, it would disclose its location in the repository if that file or directory was not readable (for example, if it had been moved).
(CVE-2015-3187)

Red Hat would like to thank the Apache Software Foundation for reporting these issues. Upstream acknowledges Evgeny Kotkov of VisualSVN as the original reporter of CVE-2015-0248 and CVE-2015-0251, and C. Michael Pilato of CollabNet as the original reporter of CVE-2015-3187.

All subversion users should upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, for the update to take effect, you must restart the httpd daemon, if you are using mod_dav_svn, and the svnserve daemon, if you are serving Subversion repositories via the svn:// protocol.

Updated kernel packages that fix two 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.

[Updated 3 September 2015] This advisory has been updated to push packages into the Red Hat Enterprise Linux 6 Client channels. The packages included in this revised update have not been changed in any way from the packages included in the original advisory.

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

Two flaws were found in the way the Linux kernel's networking implementation handled UDP packets with incorrect checksum values. A remote attacker could potentially use these flaws to trigger an infinite loop in the kernel, resulting in a denial of service on the system, or cause a denial of service in applications using the edge triggered epoll functionality. (CVE-2015-5364, CVE-2015-5366, Important)

This update also fixes the following bugs :

* When removing a directory, and a reference was held to that directory by a reference to a negative child dentry, the directory dentry was previously not killed. In addition, once the negative child dentry was killed, an unlinked and unused dentry was present in the cache. As a consequence, deadlock could be caused by forcing the dentry eviction while the file system in question was frozen. With this update, all unused dentries are unhashed and evicted just after a successful directory removal, which avoids the deadlock, and the system no longer hangs in the aforementioned scenario. (BZ#1243400)

* Due to the broken s_umount lock ordering, a race condition occurred when an unlinked file was closed and the sync (or syncfs) utility was run at the same time. As a consequence, deadlock occurred on a frozen file system between sync and a process trying to unfreeze the file system. With this update, sync (or syncfs) is skipped on a frozen file system, and deadlock no longer occurs in the aforementioned situation.
(BZ#1243404)

* Previously, in the scenario when a file was opened by file handle (fhandle) with its dentry not present in dcache ('cold dcache') and then making use of the unlink() and close() functions, the inode was not freed upon the close() system call. As a consequence, the iput() final was delayed indefinitely. A patch has been provided to fix this bug, and the inode is now freed as expected. (BZ#1243406)

* Due to a corrupted Executable and Linkable Format (ELF) header in the /proc/vmcore file, the kdump utility failed to provide any information. The underlying source code has been patched, and kdump now provides debuging information for kernel crashes as intended.
(BZ#1245195)

* Previously, running the multipath request queue caused regressions in cases where paths failed regularly under I/O load. This regression manifested as I/O stalls that exceeded 300 seconds. This update reverts the changes aimed to reduce running the multipath request queue resulting in I/O completing in a timely manner. (BZ#1246095)

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

* An integer overflow flaw was found in the way the Linux kernel's netfilter connection tracking implementation loaded extensions. An attacker on a local network could potentially send a sequence of specially crafted packets that would initiate the loading of a large number of extensions, causing the targeted system in that network to crash. (CVE-2014-9715, Moderate)

* A stack-based buffer overflow flaw was found in the Linux kernel's early load microcode functionality. On a system with UEFI Secure Boot enabled, a local, privileged user could use this flaw to increase their privileges to the kernel (ring0) level, bypassing intended restrictions in place. (CVE-2015-2666, Moderate)

* It was found that the Linux kernel's ping socket implementation did not properly handle socket unhashing during spurious disconnects, which could lead to a use-after-free flaw. On x86-64 architecture systems, a local user able to create ping sockets could use this flaw to crash the system. On non-x86-64 architecture systems, a local user able to create ping sockets could use this flaw to escalate their privileges on the system. (CVE-2015-3636, Moderate)

* It was found that the Linux kernel's TCP/IP protocol suite implementation for IPv6 allowed the Hop Limit value to be set to a smaller value than the default one. An attacker on a local network could use this flaw to prevent systems on that network from sending or receiving network packets. (CVE-2015-2922, Low)

Red Hat would like to thank Nathan Hoad for reporting the CVE-2014-9715 issue.

This update also fixes several bugs. Refer to the following Knowledgebase article for further information :

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 java-1.6.0-openjdk packages that fix multiple security issues are 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.

The java-1.6.0-openjdk packages provide the OpenJDK 6 Java Runtime Environment and the OpenJDK 6 Java Software Development Kit.

Multiple flaws were discovered in the 2D, CORBA, JMX, Libraries and RMI components in OpenJDK. An untrusted Java application or applet could use these flaws to bypass Java sandbox restrictions.
(CVE-2015-4760, CVE-2015-2628, CVE-2015-4731, CVE-2015-2590, CVE-2015-4732, CVE-2015-4733)

A flaw was found in the way the Libraries component of OpenJDK verified Online Certificate Status Protocol (OCSP) responses. An OCSP response with no nextUpdate date specified was incorrectly handled as having unlimited validity, possibly causing a revoked X.509 certificate to be interpreted as valid. (CVE-2015-4748)

It was discovered that the JCE component in OpenJDK failed to use constant time comparisons in multiple cases. An attacker could possibly use these flaws to disclose sensitive information by measuring the time used to perform operations using these non-constant time comparisons. (CVE-2015-2601)

A flaw was found in the RC4 encryption algorithm. When using certain keys for RC4 encryption, an attacker could obtain portions of the plain text from the cipher text without the knowledge of the encryption key. (CVE-2015-2808)

Note: With this update, OpenJDK now disables RC4 TLS/SSL cipher suites by default to address the CVE-2015-2808 issue. Refer to Red Hat Bugzilla bug 1207101, linked to in the References section, for additional details about this change.

A flaw was found in the way the TLS protocol composed 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 to decrypt all traffic.
(CVE-2015-4000)

Note: This update forces the TLS/SSL client implementation in OpenJDK to reject DH key sizes below 768 bits, which prevents sessions to be downgraded to export-grade keys. Refer to Red Hat Bugzilla bug 1223211, linked to in the References section, for additional details about this change.

It was discovered that the JNDI component in OpenJDK did not handle DNS resolutions correctly. An attacker able to trigger such DNS errors could cause a Java application using JNDI to consume memory and CPU time, and possibly block further DNS resolution. (CVE-2015-4749)

Multiple information leak flaws were found in the JMX and 2D components in OpenJDK. An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions.
(CVE-2015-2621, CVE-2015-2632)

A flaw was found in the way the JSSE component in OpenJDK performed X.509 certificate identity verification when establishing a TLS/SSL connection to a host identified by an IP address. In certain cases, the certificate was accepted as valid if it was issued for a host name to which the IP address resolves rather than for the IP address.
(CVE-2015-2625)

All users of java-1.6.0-openjdk are advised to upgrade to these updated packages, which resolve these issues. All running instances of OpenJDK Java must be restarted for the update to take effect.

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 flaw was found in the way BIND handled requests for TKEY DNS resource records. A remote attacker could use this flaw to make named (functioning as an authoritative DNS server or a DNS resolver) exit unexpectedly with an assertion failure via a specially crafted DNS request packet. (CVE-2015-5477)

Red Hat would like to thank ISC for reporting this issue. Upstream acknowledges Jonathan Foote as the original reporter.

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 heap buffer overflow flaw was found in the way QEMU's IDE subsystem handled I/O buffer access while processing certain ATAPI commands. A privileged guest user in a guest with the CDROM drive enabled could potentially use this flaw to execute arbitrary code on the host with the privileges of the host's QEMU process corresponding to the guest.
(CVE-2015-5154)

An out-of-bounds memory access flaw, leading to memory corruption or possibly an information leak, was found in QEMU's pit_ioport_read() function. A privileged guest user in a QEMU guest, which had QEMU PIT emulation enabled, could potentially, in rare cases, use this flaw to execute arbitrary code on the host with the privileges of the hosting QEMU process. (CVE-2015-3214)

Red Hat would like to thank Matt Tait of Google's Project Zero security team for reporting the CVE-2015-3214 issue. The CVE-2015-5154 issue was discovered by Kevin Wolf of Red Hat.

This update also fixes the following bug :

* Due to an incorrect implementation of portable memory barriers, the QEMU emulator in some cases terminated unexpectedly when a virtual disk was under heavy I/O load. This update fixes the implementation in order to achieve correct synchronization between QEMU's threads. As a result, the described crash no longer occurs. (BZ#1233643)

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

Red Hat Identity Management (IdM) is a centralized authentication, identity management, and authorization solution for both traditional and cloud-based enterprise environments.

Two cross-site scripting (XSS) flaws were found in jQuery, which impacted the Identity Management web administrative interface, and could allow an authenticated user to inject arbitrary HTML or web script into the interface. (CVE-2010-5312, CVE-2012-6662)

Note: The IdM version provided by this update no longer uses jQuery.

Bug fixes :

* The ipa-server-install, ipa-replica-install, and ipa-client-install utilities are not supported on machines running in FIPS-140 mode.
Previously, IdM did not warn users about this. Now, IdM does not allow running the utilities in FIPS-140 mode, and displays an explanatory message. (BZ#1131571)

* If an Active Directory (AD) server was specified or discovered automatically when running the ipa-client-install utility, the utility produced a traceback instead of informing the user that an IdM server is expected in this situation. Now, ipa-client-install detects the AD server and fails with an explanatory message. (BZ#1132261)

* When IdM servers were configured to require the TLS protocol version 1.1 (TLSv1.1) or later in the httpd server, the ipa utility failed.
With this update, running ipa works as expected with TLSv1.1 or later.
(BZ#1154687)

* In certain high-load environments, the Kerberos authentication step of the IdM client installer can fail. Previously, the entire client installation failed in this situation. This update modifies ipa-client-install to prefer the TCP protocol over the UDP protocol and to retry the authentication attempt in case of failure.
(BZ#1161722)

* If ipa-client-install updated or created the /etc/nsswitch.conf file, the sudo utility could terminate unexpectedly with a segmentation fault. Now, ipa-client-install puts a new line character at the end of nsswitch.conf if it modifies the last line of the file, fixing this bug. (BZ#1185207)

* The ipa-client-automount utility failed with the 'UNWILLING_TO_PERFORM' LDAP error when the nsslapd-minssf Red Hat Directory Server configuration parameter was set to '1'. This update modifies ipa-client-automount to use encrypted connection for LDAP searches by default, and the utility now finishes successfully even with nsslapd-minssf specified. (BZ#1191040)

* If installing an IdM server failed after the Certificate Authority (CA) installation, the 'ipa-server-install --uninstall' command did not perform a proper cleanup. After the user issued 'ipa-server-install --uninstall' and then attempted to install the server again, the installation failed. Now, 'ipa-server-install
--uninstall' removes the CA-related files in the described situation, and ipa-server-install no longer fails with the mentioned error message. (BZ#1198160)

* Running ipa-client-install added the 'sss' entry to the sudoers line in nsswitch.conf even if 'sss' was already configured and the entry was present in the file. Duplicate 'sss' then caused sudo to become unresponsive. Now, ipa-client-install no longer adds 'sss' if it is already present in nsswitch.conf. (BZ#1198339)

* After running ipa-client-install, it was not possible to log in using SSH under certain circumstances. Now, ipa-client-install no longer corrupts the sshd_config file, and the sshd service can start as expected, and logging in using SSH works in the described situation. (BZ#1201454)

* An incorrect definition of the dc attribute in the /usr/share/ipa/05rfc2247.ldif file caused bogus error messages to be returned during migration. The attribute has been fixed, but the bug persists if the copy-schema-to-ca.py script was run on Red Hat Enterprise Linux 6.6 prior to running it on Red Hat Enterprise Linux 6.7. To work around this problem, manually copy /usr/share/ipa/schema/05rfc2247.ldif to /etc/dirsrv/slapd-PKI-IPA/schema/ and restart IdM. (BZ#1220788)

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

Updated wireshark packages that fix multiple security issues, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 6.

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.

Wireshark, previously known as Ethereal, is a network protocol analyzer, which is 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-2014-8714, CVE-2014-8712, CVE-2014-8713, CVE-2014-8711, CVE-2014-8710, CVE-2015-0562, CVE-2015-0564, CVE-2015-2189, CVE-2015-2191)

This update also fixes the following bugs :

* Previously, the Wireshark tool did not support Advanced Encryption Standard Galois/Counter Mode (AES-GCM) cryptographic algorithm. As a consequence, AES-GCM was not decrypted. Support for AES-GCM has been added to Wireshark, and AES-GCM is now correctly decrypted.
(BZ#1095065)

* Previously, when installing the system using the kickstart method, a dependency on the shadow-utils packages was missing from the wireshark packages, which could cause the installation to fail with a 'bad scriptlet' error message. With this update, shadow-utils are listed as required in the wireshark packages spec file, and kickstart installation no longer fails. (BZ#1121275)

* Prior to this update, the Wireshark tool could not decode types of elliptic curves in Datagram Transport Layer Security (DTLS) Client Hello. Consequently, Wireshark incorrectly displayed elliptic curves types as data. A patch has been applied to address this bug, and Wireshark now decodes elliptic curves types properly. (BZ#1131203)

* Previously, a dependency on the gtk2 packages was missing from the wireshark packages. As a consequence, the Wireshark tool failed to start under certain circumstances due to an unresolved symbol, 'gtk_combo_box_text_new_with_entry', which was added in gtk version 2.24. With this update, a dependency on gtk2 has been added, and Wireshark now always starts as expected. (BZ#1160388)

In addition, this update adds the following enhancements :

* With this update, the Wireshark tool supports process substitution, which feeds the output of a process (or processes) into the standard input of another process using the '<(command_list)' syntax. When using process substitution with large files as input, Wireshark failed to decode such input. (BZ#1104210)

* Wireshark has been enhanced to enable capturing packets with nanosecond time stamp precision, which allows better analysis of recorded network traffic. (BZ#1146578)

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

Updated ntp packages that fix multiple security issues, several bugs, and add two enhancements are now available for Red Hat Enterprise Linux 6.

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.

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)

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)

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 daemon 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. The maximum length of keys has now been changed to 32 bytes. (BZ#1053551)

* The ntp-keygen utility used the exponent of 3 when generating RSA keys, and generating RSA keys failed when FIPS mode was enabled.
ntp-keygen has been modified to use the exponent of 65537, and generating keys in FIPS mode now works as expected. (BZ#1184421)

* The ntpd daemon included a root delay when calculating its root dispersion. Consequently, the NTP server reported larger root dispersion than it should have and clients could reject the source when its distance reached the maximum synchronization distance (1.5 seconds by default). Calculation of root dispersion has been fixed, the root dispersion is now reported correctly, and clients no longer reject the server due to a large synchronization distance.
(BZ#1045376)

* The ntpd daemon dropped incoming NTP packets if their source port was lower than 123 (the NTP port). Clients behind Network Address Translation (NAT) were unable to synchronize with the server if their source port was translated to ports below 123. With this update, ntpd no longer checks the source port number. (BZ#1171630)

Enhancements :

* This update introduces configurable access of memory segments used for Shared Memory Driver (SHM) reference clocks. Previously, only the first two memory segments were created with owner-only access, allowing just two SHM reference clocks to be used securely on a system. Now, the owner-only access to SHM is configurable with the 'mode' option, and it is therefore possible to use more SHM reference clocks securely. (BZ#1122015)

* Support for nanosecond resolution has been added to the 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 (for example, with the timemaster service from the linuxptp package), the accuracy of the synchronization was limited due to the microsecond resolution of the SHM protocol. The nanosecond extension in the SHM protocol now enables sub-microsecond synchronization of the system clock. (BZ#1117704)

Updated libreoffice packages that fix one security issue, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 6.

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.

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.

A flaw was found in the way the LibreOffice HWP (Hangul Word Processor) file filter processed certain HWP documents. An attacker able to trick a user into opening a specially crafted HWP document could possibly use this flaw to execute arbitrary code with the privileges of the user opening that document. (CVE-2015-1774)

The libreoffice packages have been upgraded to upstream version 4.2.8.2, which provides a number of bug fixes and enhancements over the previous version, including :

* OpenXML interoperability has been improved.

* This update adds additional statistics functions to the Calc application, thus improving interoperability with Microsoft Excel and its 'Analysis ToolPak' add-in.

* Various performance improvements have been implemented in Calc.

* This update adds new import filters for importing files from the Appple Keynote and Abiword applications.

* The export filter for the MathML markup language has been improved.

* This update adds a new start screen that includes thumbnails of recently opened documents.

* A visual clue is now displayed in the Slide Sorter window for slides with transitions or animations.

* This update improves trend lines in charts.

* LibreOffice now supports BCP 47 language tags.

For a complete list of bug fixes and enhancements provided by this rebase, see the libreoffice change log linked from the References section. (BZ#1150048)

Users of libreoffice are advised to upgrade to these updated packages, which correct these issues and add these enhancements.

Updated gnutls packages that fix three security issues and one bug are now available for Red Hat Enterprise Linux 6.

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 GnuTLS library provides support for cryptographic algorithms and for protocols such as Transport Layer Security (TLS).

It was found that GnuTLS did not check activation and expiration dates of CA certificates. This could cause an application using GnuTLS to incorrectly accept a certificate as valid when its issuing CA is already expired. (CVE-2014-8155)

It was found that GnuTLS did not verify whether a hashing algorithm listed in a signature matched the hashing algorithm listed in the certificate. An attacker could create a certificate that used a different hashing algorithm than it claimed, possibly causing GnuTLS to use an insecure, disallowed hashing algorithm during certificate verification. (CVE-2015-0282)

It was discovered that GnuTLS did not check if all sections of X.509 certificates indicate the same signature algorithm. This flaw, in combination with a different flaw, could possibly lead to a bypass of the certificate signature check. (CVE-2015-0294)

The CVE-2014-8155 issue was discovered by Marcel Kolaja of Red Hat.
The CVE-2015-0282 and CVE-2015-0294 issues were discovered by Nikos Mavrogiannopoulos of the Red Hat Security Technologies Team.

This update also fixes the following bug :

* Previously, under certain circumstances, the certtool utility could generate X.509 certificates which contained a negative modulus.
Consequently, such certificates could have interoperation problems with the software using them. The bug has been fixed, and certtool no longer generates X.509 certificates containing a negative modulus.
(BZ#1036385)

Users of gnutls are advised to upgrade to these updated packages, which contain backported patches to correct these issues.

Updated grep packages that fix two security issues, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having Low 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 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.

An integer overflow flaw, leading to a heap-based buffer overflow, was found in the way grep parsed large lines of data. An attacker able to trick a user into running grep on a specially crafted data file could use this flaw to crash grep or, potentially, execute arbitrary code with the privileges of the user running grep. (CVE-2012-5667)

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)

The grep packages have been upgraded to upstream version 2.20, which provides a number of bug fixes and enhancements over the previous version. Notably, the speed of various operations has been improved significantly. Now, the recursive grep utility uses the fts function of the gnulib library for directory traversal, so that it can handle much larger directories without reporting the 'File name too long' error message, and it can operate faster when dealing with large directory hierarchies. (BZ#982215, BZ#1064668, BZ#1126757, BZ#1167766, BZ#1171806)

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, regular expressions that used \w and \W in some cases had incorrect results.
An upstream patch which fixes the matching problem has been applied, and \w is now matched to the [_ [:alnum:]] character and \W to the [^_[:alnum:]] character consistently. (BZ#799863)

* Previously, the '--fixed-regexp' command-line option was not included in the grep(1) manual page. Consequently, the manual page was inconsistent with the built-in help of the grep utility. To fix this bug, grep(1) has been updated to include a note informing the user that '--fixed-regexp' is an obsolete option. Now, the built-in help and manual page are consistent regarding the '--fixed-regexp' option.
(BZ#1103270)

* Previously, the Perl Compatible Regular Expression (PCRE) library did not work correctly when matching non-UTF-8 text in UTF-8 mode.
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 PCRE library and the grep utility. As a result, PCRE now skips non-UTF-8 characters as non-matching text without returning any error message. (BZ#1193030)

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

An updated wpa_supplicant package that fixes one security issue and adds one enhancement is now available for Red Hat Enterprise Linux 6.

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 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.

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)

This update includes 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#1186806)

All wpa_supplicant users are advised to upgrade to this updated package, which contains a backported patch to correct this issue and adds this enhancement. After installing this update, the wpa_supplicant service will be restarted automatically.

Updated pacemaker packages that fix one security issue and several bugs are now available for Red Hat Enterprise Linux 6.

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)

This update also fixes the following bugs :

* Due to a race condition, nodes that gracefully shut down occasionally had difficulty rejoining the cluster. As a consequence, nodes could come online and be shut down again immediately by the cluster. This bug has been fixed, and the 'shutdown' attribute is now cleared properly. (BZ#1198638)

* Prior to this update, the pacemaker utility caused an unexpected termination of the attrd daemon after a system update to Red Hat Enterprise Linux 6.6. The bug has been fixed so that attrd no longer crashes when pacemaker starts. (BZ#1205292)

* Previously, the access control list (ACL) of the pacemaker utility allowed a role assignment to the Cluster Information Base (CIB) with a read-only permission. With this update, ACL is enforced and can no longer be bypassed by the user without the write permission, thus fixing this bug. (BZ#1207621)

* Prior to this update, the ClusterMon (crm_mon) utility did not trigger an external agent script with the '-E' parameter to monitor the Cluster Information Base (CIB) when the pacemaker utility was used. A patch has been provided to fix this bug, and crm_mon now calls the agent script when the '-E' parameter is used. (BZ#1208896)

Users of pacemaker are advised to upgrade to these updated packages, which contain backported patches to correct these issues.

Updated libxml2 packages that fix one security issue and one bug are now available for Red Hat Enterprise Linux 6.

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 libxml2 library is a development toolbox providing the implementation of various XML standards.

A denial of service flaw was found in the way the libxml2 library parsed certain XML files. An attacker could provide a specially crafted XML file that, when parsed by an application using libxml2, could cause that application to use an excessive amount of memory.
(CVE-2015-1819)

This issue was discovered by Florian Weimer of Red Hat Product Security.

This update also fixes the following bug :

This update fixes an error that occurred when running a test case for the serialization of HTML documents. (BZ#1004513)

Users of libxml2 are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The desktop must be restarted (log out, then log back in) for this update to take effect.

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

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.

Mailman is a program used to help manage e-mail 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)

It was found that mailman stored private email messages in a world-readable directory. A local user could use this flaw to read private mailing list archives. (CVE-2002-0389)

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#1095359)

* Mailman used a console encoding when generating a subject for a 'welcome email' when new mailing lists were created by the 'newlist' command. Consequently, when the console encoding did not match the encoding used by Mailman for that particular language, characters in the 'welcome email' could be displayed incorrectly. Mailman has been fixed to use the correct encoding, and characters in the 'welcome email' are now displayed properly. (BZ#1056366)

* The 'rmlist' command used a hard-coded path to list data based on the VAR_PREFIX configuration variable. As a consequence, when the list was created outside of VAR_PREFIX, it was impossible to remove it using the 'rmlist' command. With this update, the 'rmlist' command uses the correct LIST_DATA_DIR value instead of VAR_PREFIX, and it is now possible to remove the list in described situation. (BZ#1008139)

* Due to an incompatibility between Python and Mailman in Red Hat Enterprise Linux 6, when moderators were approving a moderated message to a mailing list and checked the 'Preserve messages for the site administrator' checkbox, Mailman failed to approve the message and returned an error. This incompatibility has been fixed, and Mailman now approves messages as expected in this scenario. (BZ#765807)

* When Mailman was set to not archive a list but the archive was not set to private, attachments sent to that list were placed in a public archive. Consequently, users of Mailman web interface could list private attachments because httpd configuration of public archive directory allows listing all files in the archive directory. The httpd configuration of Mailman has been fixed to not allow listing of private archive directory, and users of Mailman web interface are no longer able to list private attachments. (BZ#745409)

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

Updated sudo packages that fix one security issue, three bugs, and add one enhancement are now available for Red Hat Enterprise Linux 6.

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 sudo packages contain the sudo utility which allows system administrators to provide certain users with the permission to execute privileged commands, which are used for system management purposes, without having to log in as root.

It was discovered that sudo did not perform any checks of the TZ environment variable value. If sudo was configured to preserve the TZ environment variable, a local user with privileges to execute commands via sudo could possibly use this flaw to achieve system state changes not permitted by the configured commands. (CVE-2014-9680)

Note: The default sudoers configuration in Red Hat Enterprise Linux removes the TZ variable from the environment in which commands run by sudo are executed.

This update also fixes the following bugs :

* Previously, the sudo utility child processes could sometimes become unresponsive because they ignored the SIGPIPE signal. With this update, SIGPIPE handler is properly restored in the function that reads passwords from the user, and the child processes no longer ignore SIGPIPE. As a result, sudo child processes do not hang in this situation. (BZ#1094548)

* Prior to this update, the order in which sudo rules were processed did not honor the user-defined sudoOrder attribute. Consequently, sudo rules were processed in an undefined order even when the user defined the order in sudoOrder. The implementation of SSSD support in sudo has been modified to sort the rules according to the sudoOrder value, and sudo rules are now sorted in the order defined by the user in sudoOrder. (BZ#1138581)

* Previously, sudo became unresponsive after the user issued a command when a sudoers source was mentioned multiple times in the /etc/nsswitch.conf file. The problem occurred when nsswitch.conf contained, for example, the 'sudoers: files sss sss' entry. The sudoers source processing code has been fixed to correctly handle multiple instances of the same sudoers source. As a result, sudo no longer hangs when a sudoers source is mentioned multiple times in /etc/nsswitch.conf. (BZ#1147498)

In addition, this update adds the following enhancement :

* The sudo utility now supports I/O logs compressed using the zlib library. With this update, sudo can generate zlib compressed I/O logs and also process zlib compressed I/O logs generated by other versions of sudo with zlib support. (BZ#1106433)

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

Updated net-snmp packages that fix one security issue and several bugs are now available for Red Hat Enterprise Linux 6.

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 :

* The HOST-RESOURCES-MIB::hrSystemProcesses object was not implemented because parts of the HOST-RESOURCES-MIB module were rewritten in an earlier version of net-snmp. Consequently, HOST-RESOURCES-MIB::hrSystemProcesses did not provide information on the number of currently loaded or running processes. With this update, HOST-RESOURCES-MIB::hrSystemProcesses has been implemented, and the net-snmp daemon reports as expected. (BZ#1134335)

* The Net-SNMP agent daemon, snmpd, reloaded the system ARP table every 60 seconds. As a consequence, snmpd could cause a short CPU usage spike on busy systems with a large APR table. With this update, snmpd does not reload the full ARP table periodically, but monitors the table changes using a netlink socket. (BZ#789500)

* Previously, snmpd used an invalid pointer to the current time when periodically checking certain conditions specified by the 'monitor' option in the /etc/snmpd/snmpd.conf file. Consequently, snmpd terminated unexpectedly on start with a segmentation fault if a certain entry with the 'monitor' option was used. Now, snmpd initializes the correct pointer to the current time, and snmpd no longer crashes on start. (BZ#1050970)

* Previously, snmpd expected 8-bit network interface indices when processing HOST-RESOURCES-MIB::hrDeviceTable. If an interface index of a local network interface was larger than 30,000 items, snmpd could terminate unexpectedly due to accessing invalid memory. Now, processing of all network sizes is enabled, and snmpd no longer crashes in the described situation. (BZ#1195547)

* The snmpdtrapd service incorrectly checked for errors when forwarding a trap with a RequestID value of 0, and logged 'Forward failed' even though the trap was successfully forwarded. This update fixes snmptrapd checks and the aforementioned message is now logged only when appropriate. (BZ#1146948)

* Previously, snmpd ignored the value of the 'storageUseNFS' option in the /etc/snmpd/snmpd.conf file. As a consequence, NFS drivers were shown as 'Network Disks', even though 'storageUseNFS' was set to '2' to report them as 'Fixed Disks' in HOST-RESOURCES-MIB::hrStorageTable.
With this update, snmpd takes the 'storageUseNFS' option value into account, and 'Fixed Disks' NFS drives are reported correctly.
(BZ#1125793)

* Previously, the Net-SNMP python binding used an incorrect size (8 bytes instead of 4) for variables of IPADDRESS type. Consequently, applications that were using Net-SNMP Python bindings could send malformed SNMP messages. With this update, the bindings now use 4 bytes for variables with IPADRESS type, and only valid SNMP messages are sent. (BZ#1100099)

* Previously, the snmpd service did not cut values in HOST-RESOURCES-MIB::hrStorageTable to signed 32-bit integers, as required by SNMP standards, and provided the values as unsigned integers. As a consequence, the HOST-RESOURCES-MIB::hrStorageTable implementation did not conform to RFC 2790. The values are now cut to 32-bit signed integers, and snmpd is therefore standard compliant.
(BZ#1104293)

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

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

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.

Hivex is a library that can read and write Hive files, undocumented binary files that Windows uses to store the Windows Registry on disk.

It was found that hivex attempted to read, and possibly write, beyond its allocated buffer when reading a hive file with a very small size or with a truncated or improperly formatted content. An attacker able to supply a specially crafted hive file to an application using the hivex library could possibly use this flaw to execute arbitrary code with the privileges of the user running that application.
(CVE-2014-9273)

Red Hat would like to thank Mahmoud Al-Qudsi of NeoSmart Technologies for reporting this issue.

This update also fixes the following bug :

* The hivex(3) man page previously contained a typographical error.
This update fixes the typo. (BZ#1164693)

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

Updated pki-core packages that fix one security issue and several bugs are now available for Red Hat Enterprise Linux 6.

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.

Red Hat Certificate System is an enterprise software system designed to manage enterprise public key infrastructure (PKI) deployments. PKI Core contains fundamental packages required by Red Hat Certificate System, which comprise the Certificate Authority (CA) subsystem.

Multiple cross-site scripting flaws were discovered in the Red Hat Certificate System Agent and End Entity pages. An attacker could use these flaws to perform a cross-site scripting (XSS) attack against victims using the Certificate System's web interface. (CVE-2012-2662)

This update also fixes the following bugs :

* Previously, pki-core required the SSL version 3 (SSLv3) protocol ranges to communicate with the 389-ds-base packages. However, recent changes to 389-ds-base disabled the default use of SSLv3 and enforced using protocol ranges supported by secure protocols, such as the TLS protocol. As a consequence, the CA failed to install during an Identity Management (IdM) server installation. This update adds TLS-related parameters to the server.xml file of the CA to fix this problem, and running the ipa-server-install command now installs the CA as expected. (BZ#1171848)

* Previously, the ipa-server-install script failed when attempting to configure a stand-alone CA on systems with OpenJDK version 1.8.0 installed. The pki-core build and runtime dependencies have been modified to use OpenJDK version 1.7.0 during the stand-alone CA configuration. As a result, ipa-server-install no longer fails in this situation. (BZ#1212557)

* Creating a Red Hat Enterprise Linux 7 replica from a Red Hat Enterprise Linux 6 replica running the CA service sometimes failed in IdM deployments where the initial Red Hat Enterprise Linux 6 CA master had been removed. This could cause problems in some situations, such as when migrating from Red Hat Enterprise Linux 6 to Red Hat Enterprise Linux 7. The bug occurred due to a problem in a previous version of IdM where the subsystem user, created during the initial CA server installation, was removed together with the initial master.
This update adds the restore-subsystem-user.py script that restores the subsystem user in the described situation, thus enabling administrators to create a Red Hat Enterprise Linux 7 replica in this scenario. (BZ#1225589)

* Several Java import statements specify wildcard arguments. However, due to the use of wildcard arguments in the import statements of the source code contained in the Red Hat Enterprise Linux 6 maintenance branch, a name space collision created the potential for an incorrect class to be utilized. As a consequence, the Token Processing System (TPS) rebuild test failed with an error message. This update addresses the bug by supplying the fully named class in all of the affected areas, and the TPS rebuild test no longer fails. (BZ#1144188)

* Previously, pki-core failed to build with the rebased version of the CMake build system during the TPS rebuild test. The pki-core build files have been updated to comply with the rebased version of CMake.
As a result, pki-core builds successfully in the described scenario.
(BZ#1144608)

Users of pki-core are advised to upgrade to these updated packages, which contain backported patches to correct these issues.

Updated autofs packages that fix one security issue and several bugs are now available for Red Hat Enterprise Linux 6.

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 would use 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.

Bug fixes :

* If the 'ls *' command was executed before a valid mount, the autofs program failed on further mount attempts inside the mount point, whether the mount point was valid or not. While attempting to mount, the 'ls *' command of the root directory of an indirect mount was executed, which led to an attempt to mount '*', causing it to be added to the negative map entry cache. This bug has been fixed by checking for and not adding '*' while updating the negative map entry cache.
(BZ#1163957)

* The autofs program by design did not mount host map entries that were duplicate exports in an NFS server export list. The duplicate entries in a multi-mount map entry were recognized as a syntax error and autofs refused to perform mounts when the duplicate entries occurred. Now, autofs has been changed to continue mounting the last seen instance of the duplicate entry rather than fail, and to report the problem in the log files to alert the system administrator.
(BZ#1124083)

* The autofs program did not recognize the yp map type in the master map. This was caused by another change in the master map parser to fix a problem with detecting the map format associated with mapping the type in the master map. The change led to an incorrect length for the type comparison of yp maps that resulted in a match operation failure.
This bug has been fixed by correcting the length which is used for the comparison. (BZ#1153130)

* The autofs program did not update the export list of the Sun-format maps of the network shares exported from an NFS server. This happened due to a change of the Sun-format map parser leading to the hosts map update to stop working on the map re-read operation. The bug has been now fixed by selectively preventing this type of update only for the Sun-formatted maps. The updates of the export list on the Sun-format maps are now visible and refreshing of the export list is no longer supported for the Sun-formatted hosts map. (BZ#1156387)

* Within changes made for adding of the Sun-format maps, an incorrect check was added that caused a segmentation fault in the Sun-format map parser in certain circumstances. This has been now fixed by analyzing the intent of the incorrect check and changing it in order to properly identify the conditions without causing a fault. (BZ#1175671)

* A bug in the autofs program map lookup module caused an incorrect map format type comparison. The incorrect comparison affected the Sun-format program maps where it led to the unused macro definitions.
The bug in the comparison has been fixed so that the macro definitions are not present for the Sun-format program maps. (BZ#1201195)

Users of autofs 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 one enhancement are now available for Red Hat Enterprise Linux 6.

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 socket.recvfrom_into() function failed to check the size of the supplied buffer. This could lead to a buffer overflow when the function was called with an insufficiently sized buffer. (CVE-2014-1912)

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)

These updated python packages also include numerous bug fixes and enhancements. 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/1495363

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

Updated freeradius packages that fix one security issue, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 6.

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.

FreeRADIUS is a high-performance and highly configurable free Remote Authentication Dial In User Service (RADIUS) server, designed to allow centralized authentication and authorization for a network.

A stack-based buffer overflow was found in the way the FreeRADIUS rlm_pap module handled long password hashes. An attacker able to make radiusd process a malformed password hash could cause the daemon to crash. (CVE-2014-2015)

The freeradius packages have been upgraded to upstream version 2.2.6, which provides a number of bug fixes and enhancements over the previous version, including :

* The number of dictionaries have been updated.

* This update implements several Extensible Authentication Protocol (EAP) improvements.

* A number of new expansions have been added, including:
%{randstr:...}, %{hex:...}, %{sha1:...}, %{base64:...}, %{tobase64:...}, and %{base64tohex:...}.

* Hexadecimal numbers (0x...) are now supported in %{expr:...} expansions.

* This update adds operator support to the rlm_python module.

* The Dynamic Host Configuration Protocol (DHCP) and DHCP relay code have been finalized.

* This update adds the rlm_cache module to cache arbitrary attributes.

For a complete list of bug fixes and enhancements provided by this rebase, see the freeradius changelog linked to in the References section.

(BZ#1078736)

This update also fixes the following bugs :

* The /var/log/radius/radutmp file was configured to rotate at one-month intervals, even though this was unnecessary. This update removes /var/log/radius/radutmp from the installed logrotate utility configuration in the /etc/logrotate.d/radiusd file, and /var/log/radius/radutmp is no longer rotated. (BZ#904578)

* The radiusd service could not write the output file created by the raddebug utility. The raddebug utility now sets appropriate ownership to the output file, allowing radiusd to write the output. (BZ#921563)

* After starting raddebug using the 'raddebug -t 0' command, raddebug exited immediately. A typo in the special case comparison has been fixed, and raddebug now runs for 11.5 days in this situation.
(BZ#921567)

* MS-CHAP authentication failed when the User-Name and MS-CHAP-User-Name attributes used different encodings, even when the user provided correct credentials. Now, MS-CHAP authentication properly handles mismatching character encodings. Authentication with correct credentials no longer fails in this situation. (BZ#1060319)

* Automatically generated default certificates used the SHA-1 algorithm message digest, which is considered insecure. The default certificates now use the more secure SHA-256 algorithm message digest.
(BZ#1135439)

* During the Online Certificate Status Protocol (OCSP) validation, radiusd terminated unexpectedly with a segmentation fault after attempting to access the next update field that was not provided by the OCSP responder. Now, radiusd does not crash in this situation and instead continues to complete the OCSP validation. (BZ#1142669)

* Prior to this update, radiusd failed to work with some of the more recent MikroTIK attributes, because the installed directory.mikrotik file did not include them. This update adds MikroTIK attributes with IDs up to 22 to dictionary.mikrotik, and radiusd now works as expected with these attributes. (BZ#1173388)

Users of freeradius are advised to upgrade to these updated packages, which correct these issues and add these enhancements. After installing this update, the radiusd service will be restarted automatically.

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 6. This is the seventh regular update.

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

* A flaw was found in the way Linux kernel's Transparent Huge Pages (THP) implementation handled non-huge page migration. A local, unprivileged user could use this flaw to crash the kernel by migrating transparent hugepages. (CVE-2014-3940, Moderate)

* A buffer overflow flaw was found in the way the Linux kernel's eCryptfs implementation decoded encrypted file names. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-9683, Moderate)

* A race condition flaw was found between the chown and execve system calls. When changing the owner of a setuid user binary to root, the race condition could momentarily make the binary setuid root. A local, unprivileged user could potentially use this flaw to escalate their privileges on the system. (CVE-2015-3339, Moderate)

* Multiple out-of-bounds write flaws were found in the way the Cherry Cymotion keyboard driver, KYE/Genius device drivers, Logitech device drivers, Monterey Genius KB29E keyboard driver, Petalynx Maxter remote control driver, and Sunplus wireless desktop driver handled HID reports with an invalid report descriptor size. An attacker with physical access to the system could use either of these flaws to write data past an allocated memory buffer. (CVE-2014-3184, Low)

* An information leak flaw was found in the way the Linux kernel's Advanced Linux Sound Architecture (ALSA) implementation handled access of the user control's state. A local, privileged user could use this flaw to leak kernel memory to user space. (CVE-2014-4652, Low)

* It was found that the espfix functionality could be bypassed by installing a 16-bit RW data segment into GDT instead of LDT (which espfix checks), and using that segment on the stack. A local, unprivileged user could potentially use this flaw to leak kernel stack addresses. (CVE-2014-8133, Low)

* An information leak flaw was found in the Linux kernel's IEEE 802.11 wireless networking implementation. When software encryption was used, a remote attacker could use this flaw to leak up to 8 bytes of plaintext. (CVE-2014-8709, 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)

Red Hat would like to thank Andy Lutomirski for reporting the CVE-2014-8133 issue, and Nadav Amit for reporting the CVE-2015-0239 issue.

This update fixes several hundred bugs and adds numerous enhancements.
Refer to the Red Hat Enterprise Linux 6.7 Release Notes for information on the most significant of these changes, and the following Knowledgebase article for further information :

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

Updated curl packages that fix multiple security issues, several bugs, and add two enhancements are now available for Red Hat Enterprise Linux 6.

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 to 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 version 3.0 (SSLv3.0) 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 SSLv3.0 through the libcurl API. (BZ#1154059)

* A single upload transfer through the FILE protocol opened the destination file twice. If the inotify kernel subsystem monitored the file, two events were produced unnecessarily. The file is now opened only once per upload. (BZ#883002)

* Utilities using libcurl for SCP/SFTP transfers could terminate unexpectedly when the system was running in FIPS mode. (BZ#1008178)

* Using the '--retry' option with the curl utility could cause curl to terminate unexpectedly with a segmentation fault. Now, adding '--retry' no longer causes curl to crash. (BZ#1009455)

* The 'curl --trace-time' command did not use the correct local time when printing timestamps. Now, 'curl --trace-time' works as expected.
(BZ#1120196)

* The valgrind utility could report dynamically allocated memory leaks on curl exit. Now, curl performs a global shutdown of the NetScape Portable Runtime (NSPR) library on exit, and valgrind no longer reports the memory leaks. (BZ#1146528)

* Previously, libcurl returned an incorrect value of the CURLINFO_HEADER_SIZE field when a proxy server appended its own headers to the HTTP response. Now, the returned value is valid.
(BZ#1161163)

Enhancements :

* The '--tlsv1.0', '--tlsv1.1', and '--tlsv1.2' options are available for specifying the minor version of the TLS protocol to be negotiated by NSS. The '--tlsv1' option now negotiates the highest version of the TLS protocol supported by both the client and the server. (BZ#1012136)

* It is now possible to explicitly enable or disable the ECC and the new AES cipher suites to be used for TLS. (BZ#1058767, BZ#1156422)

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

Updated httpd packages that fix one security issue, several bugs, and add one enhancement are now available for Red Hat Enterprise Linux 6.

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 httpd packages provide the Apache HTTP Server, a powerful, efficient, and extensible web server.

A flaw was found in the way httpd handled HTTP Trailer headers when processing requests using chunked encoding. A malicious client could use Trailer headers to set additional HTTP headers after header processing was performed by other modules. This could, for example, lead to a bypass of header restrictions defined with mod_headers.
(CVE-2013-5704)

This update also fixes the following bugs :

* The order of mod_proxy workers was not checked when httpd configuration was reloaded. When mod_proxy workers were removed, added, or their order was changed, their parameters and scores could become mixed. The order of mod_proxy workers has been made internally consistent during configuration reload. (BZ#1149906)

* The local host certificate created during firstboot contained CA extensions, which caused the httpd service to return warning messages.
This has been addressed by local host certificates being generated with the '-extensions v3_req' option. (BZ#906476)

* The default mod_ssl configuration no longer enables support for SSL cipher suites using the single DES, IDEA, or SEED encryption algorithms. (BZ#1086771)

* The apachectl script did not take into account the HTTPD_LANG variable set in the /etc/sysconfig/httpd file during graceful restarts. Consequently, httpd did not use a changed value of HTTPD_LANG when the daemon was restarted gracefully. The script has been fixed to handle the HTTPD_LANG variable correctly. (BZ#963146)

* The mod_deflate module failed to check the original file size while extracting files larger than 4 GB, making it impossible to extract large files. Now, mod_deflate checks the original file size properly according to RFC1952, and it is able to decompress files larger than 4 GB. (BZ#1057695)

* The httpd service did not check configuration before restart. When a configuration contained an error, an attempt to restart httpd gracefully failed. Now, httpd checks configuration before restart and if the configuration is in an inconsistent state, an error message is printed, httpd is not stopped and a restart is not performed.
(BZ#1146194)

* The SSL_CLIENT_VERIFY environment variable was incorrectly handled when the 'SSLVerifyClient optional_no_ca' and 'SSLSessionCache' options were used. When an SSL session was resumed, the SSL_CLIENT_VERIFY value was set to 'SUCCESS' instead of the previously set 'GENEROUS'. SSL_CLIENT_VERIFY is now correctly set to GENEROUS in this scenario. (BZ#1149703)

* The ab utility did not correctly handle situations when an SSL connection was closed after some data had already been read. As a consequence, ab did not work correctly with SSL servers and printed 'SSL read failed' error messages. With this update, ab works as expected with HTTPS servers. (BZ#1045477)

* When a client presented a revoked certificate, log entries were created only at the debug level. The log level of messages regarding a revoked certificate has been increased to INFO, and administrators are now properly informed of this situation. (BZ#1161328)

In addition, this update adds the following enhancement :

* A mod_proxy worker can now be set into drain mode (N) using the balancer-manager web interface or using the httpd configuration file.
A worker in drain mode accepts only existing sticky sessions destined for itself and ignores all other requests. The worker waits until all clients currently connected to this worker complete their work before the worker is stopped. As a result, drain mode enables to perform maintenance on a worker without affecting clients. (BZ#767130)

Users of httpd are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add this enhancement. After installing the updated packages, the httpd service will be restarted automatically.

Updated libuser packages that fix two security issues 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 libuser library implements a standardized interface for manipulating and administering user and group accounts. Sample applications that are modeled after applications from the shadow password suite (shadow-utils) are included in these packages.

Two flaws were found in the way the libuser library handled the /etc/passwd file. A local attacker could use an application compiled against libuser (for example, userhelper) to manipulate the /etc/passwd file, which could result in a denial of service or possibly allow the attacker to escalate their privileges to root.
(CVE-2015-3245, CVE-2015-3246)

Red Hat would like to thank Qualys for reporting these issues.

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

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-2015-2724, CVE-2015-2725, CVE-2015-2731, CVE-2015-2734, CVE-2015-2735, CVE-2015-2736, CVE-2015-2737, CVE-2015-2738, CVE-2015-2739, CVE-2015-2740)

It was found that Thunderbird skipped key-pinning checks when handling an error that could be overridden by the user (for example an expired certificate error). This flaw allowed a user to override a pinned certificate, which is an action the user should not be able to perform. (CVE-2015-2741)

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 Bob Clary, Christian Holler, Bobby Holley, Andrew McCreight, Herre, Ronald Crane, and David Keeler as the original reporters of these issues.

For technical details regarding these flaws, refer to the Mozilla security advisories for Thunderbird 31.8. 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 31.8, which corrects these issues. After installing the update, Thunderbird must be restarted for the changes to take effect.

Updated bind 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 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 flaw was found in the way BIND performed DNSSEC validation. An attacker able to make BIND (functioning as a DNS resolver with DNSSEC validation enabled) resolve a name in an attacker-controlled domain could cause named to exit unexpectedly with an assertion failure.
(CVE-2015-4620)

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 java-1.7.0-openjdk packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5.

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 java-1.7.0-openjdk packages provide the OpenJDK 7 Java Runtime Environment and the OpenJDK 7 Java Software Development Kit.

Multiple flaws were discovered in the 2D, CORBA, JMX, Libraries and RMI components in OpenJDK. An untrusted Java application or applet could use these flaws to bypass certain Java sandbox restrictions.
(CVE-2015-4760, CVE-2015-2628, CVE-2015-4731, CVE-2015-2590, CVE-2015-4732, CVE-2015-4733)

A flaw was found in the way the Libraries component of OpenJDK verified Online Certificate Status Protocol (OCSP) responses. An OCSP response with no nextUpdate date specified was incorrectly handled as having unlimited validity, possibly causing a revoked X.509 certificate to be interpreted as valid. (CVE-2015-4748)

It was discovered that the JCE component in OpenJDK failed to use constant time comparisons in multiple cases. An attacker could possibly use these flaws to disclose sensitive information by measuring the time used to perform operations using these non-constant time comparisons. (CVE-2015-2601)

A flaw was found in the RC4 encryption algorithm. When using certain keys for RC4 encryption, an attacker could obtain portions of the plain text from the cipher text without the knowledge of the encryption key. (CVE-2015-2808)

Note: With this update, OpenJDK now disables RC4 SSL/TLS cipher suites by default to address the CVE-2015-2808 issue. Refer to Red Hat Bugzilla bug 1207101, linked to in the References section, for additional details about this change.

A flaw was found in the way the TLS protocol composed 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 OpenJDK to reject DH key sizes below 768 bits, which prevents sessions to be downgraded to export-grade keys. Refer to Red Hat Bugzilla bug 1223211, linked to in the References section, for additional details about this change.

It was discovered that the JNDI component in OpenJDK did not handle DNS resolutions correctly. An attacker able to trigger such DNS errors could cause a Java application using JNDI to consume memory and CPU time, and possibly block further DNS resolution. (CVE-2015-4749)

Multiple information leak flaws were found in the JMX and 2D components in OpenJDK. An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions.
(CVE-2015-2621, CVE-2015-2632)

A flaw was found in the way the JSSE component in OpenJDK performed X.509 certificate identity verification when establishing a TLS/SSL connection to a host identified by an IP address. In certain cases, the certificate was accepted as valid if it was issued for a host name to which the IP address resolves rather than for the IP address.
(CVE-2015-2625)

All users of java-1.7.0-openjdk are advised to upgrade to these updated packages, which resolve these issues. All running instances of OpenJDK Java must be restarted for the update to take effect.

It was discovered that the GCM (Galois Counter Mode) implementation in the Security component of OpenJDK failed to properly perform a null check. This could cause the Java Virtual Machine to crash when an application performed encryption using a block cipher in the GCM mode.
(CVE-2015-2659)

A flaw was found in the RC4 encryption algorithm. When using certain keys for RC4 encryption, an attacker could obtain portions of the plain text from the cipher text without the knowledge of the encryption key. (CVE-2015-2808)

Note: With this update, OpenJDK now disables RC4 TLS/SSL cipher suites by default to address the CVE-2015-2808 issue. Refer to Red Hat Bugzilla bug 1207101, linked to in the References section, for additional details about this change.

A flaw was found in the way the TLS protocol composed 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 OpenJDK to reject DH key sizes below 768 bits, which prevents sessions to be downgraded to export-grade keys. Refer to Red Hat Bugzilla bug 1223211, linked to in the References section, for additional details about this change.

It was discovered that the JNDI component in OpenJDK did not handle DNS resolutions correctly. An attacker able to trigger such DNS errors could cause a Java application using JNDI to consume memory and CPU time, and possibly block further DNS resolution. (CVE-2015-4749)

Multiple information leak flaws were found in the JMX and 2D components in OpenJDK. An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions.
(CVE-2015-2621, CVE-2015-2632)

A flaw was found in the way the JSSE component in OpenJDK performed X.509 certificate identity verification when establishing a TLS/SSL connection to a host identified by an IP address. In certain cases, the certificate was accepted as valid if it was issued for a host name to which the IP address resolves rather than for the IP address.
(CVE-2015-2625)

Multiple insecure temporary file use issues were found in the way the Hotspot component in OpenJDK created performance statistics and error log files. A local attacker could possibly make a victim using OpenJDK overwrite arbitrary files using a symlink attack.
