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

The Red Hat Security Response Team 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.

KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on AMD64 and Intel 64 systems that is built into the standard Red Hat Enterprise Linux kernel. The qemu-kvm packages form the user-space component for running virtual machines using KVM.

A buffer overflow flaw was found in the way QEMU processed the SCSI 'REPORT LUNS' command when more than 256 LUNs were specified for a single SCSI target. A privileged guest user could use this flaw to corrupt QEMU process memory on the host, which could potentially result in arbitrary code execution on the host with the privileges of the QEMU process. (CVE-2013-4344)

This issue was discovered by Asias He of Red Hat.

These updated qemu-kvm packages include numerous bug fixes and various enhancements. Space precludes documenting all of these changes in this advisory. Users are directed to the Red Hat Enterprise Linux 6.5 Technical Notes, linked to in the References, for information on the most significant of these changes.

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

Updated samba4 packages that fix one security issue and two bugs are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team 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.

Samba is an open source implementation of the Server Message Block (SMB) or Common Internet File System (CIFS) protocol, which allows PC-compatible machines to share files, printers, and other information.

An integer overflow flaw was found in the way Samba handled an Extended Attribute (EA) list provided by a client. A malicious client could send a specially crafted EA list that triggered an overflow, causing the server to loop and reprocess the list using an excessive amount of memory. (CVE-2013-4124)

Note: This issue did not affect the default configuration of the Samba server.

This update fixes the following bugs :

* When Samba was installed in the build root directory, the RPM target might not have existed. Consequently, the find-debuginfo.sh script did not create symbolic links for the libwbclient.so.debug module associated with the target. With this update, the paths to the symbolic links are relative so that the symbolic links are now created correctly. (BZ#882338)

* Previously, the samba4 packages were missing a dependency for the libreplace.so module which could lead to installation failures. With this update, the missing dependency has been added to the dependency list of the samba4 packages and installation now proceeds as expected.
(BZ#911264)

All samba4 users are advised to upgrade to these updated packages, which contain a backported patch to correct these issues.

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

The Red Hat Security Response Team 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.

Samba is an open source implementation of the Server Message Block (SMB) or Common Internet File System (CIFS) protocol, which allows PC-compatible machines to share files, printers, and other information.

It was discovered that the Samba Web Administration Tool (SWAT) did not protect against being opened in a web page frame. A remote attacker could possibly use this flaw to conduct a clickjacking attack against SWAT users or users with an active SWAT session.
(CVE-2013-0213)

A flaw was found in the Cross-Site Request Forgery (CSRF) protection mechanism implemented in SWAT. An attacker with the knowledge of a victim's password could use this flaw to bypass CSRF protections and conduct a CSRF attack against the victim SWAT user. (CVE-2013-0214)

An integer overflow flaw was found in the way Samba handled an Extended Attribute (EA) list provided by a client. A malicious client could send a specially crafted EA list that triggered an overflow, causing the server to loop and reprocess the list using an excessive amount of memory. (CVE-2013-4124)

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

The Red Hat Security Response Team 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.

Evolution is the integrated collection of email, calendaring, contact management, communications, and personal information management (PIM) tools for the GNOME desktop environment.

A flaw was found in the way Evolution selected GnuPG public keys when encrypting emails. This could result in emails being encrypted with public keys other than the one belonging to the intended recipient.
(CVE-2013-4166)

The Evolution packages have been upgraded to upstream version 2.32.3, which provides a number of bug fixes and enhancements over the previous version. These changes include implementation of Gnome XDG Config Folders, and support for Exchange Web Services (EWS) protocol to connect to Microsoft Exchange servers. EWS support has been added as a part of the evolution-exchange packages. (BZ#883010, BZ#883014, BZ#883015, BZ#883017, BZ#524917, BZ#524921, BZ#883044)

The gtkhtml3 packages have been upgraded to upstream version 2.32.2, which provides a number of bug fixes and enhancements over the previous version. (BZ#883019)

The libgdata packages have been upgraded to upstream version 0.6.4, which provides a number of bug fixes and enhancements over the previous version. (BZ#883032)

This update also fixes the following bug :

* The Exchange Calendar could not fetch the 'Free' and 'Busy' information for meeting attendees when using Microsoft Exchange 2010 servers, and this information thus could not be displayed. This happened because Microsoft Exchange 2010 servers use more strict rules for 'Free' and 'Busy' information fetching. With this update, the respective code in the openchange packages has been modified so the 'Free' and 'Busy' information fetching now complies with the fetching rules on Microsoft Exchange 2010 servers. The 'Free' and 'Busy' information can now be displayed as expected in the Exchange Calendar.
(BZ#665967)

All Evolution 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 Evolution must be restarted for this update to take effect.

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

The Red Hat Security Response Team 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.

Augeas is a utility for editing configuration. Augeas parses configuration files in their native formats and transforms them into a tree. Configuration changes are made by manipulating this tree and saving it back into native configuration files. Augeas also uses 'lenses' as basic building blocks for establishing the mapping from files into the Augeas tree and back.

Multiple flaws were found in the way Augeas handled configuration files when updating them. An application using Augeas to update configuration files in a directory that is writable to by a different user (for example, an application running as root that is updating files in a directory owned by a non-root service user) could have been tricked into overwriting arbitrary files or leaking information via a symbolic link or mount point attack. (CVE-2012-0786, CVE-2012-0787)

The augeas package has been upgraded to upstream version 1.0.0, which provides a number of bug fixes and enhancements over the previous version. (BZ#817753)

This update also fixes the following bugs :

* Previously, when single quotes were used in an XML attribute, Augeas was unable to parse the file with the XML lens. An upstream patch has been provided ensuring that single quotes are handled as valid characters and parsing no longer fails. (BZ#799885)

* Prior to this update, Augeas was unable to set up the 'require_ssl_reuse' option in the vsftpd.conf file. The updated patch fixes the vsftpd lens to properly recognize this option, thus fixing this bug. (BZ#855022)

* Previously, the XML lens did not support non-Unix line endings.
Consequently, Augeas was unable to load any files containing such line endings. The XML lens has been fixed to handle files with CRLF line endings, thus fixing this bug. (BZ#799879)

* Previously, Augeas was unable to parse modprobe.conf files with spaces around '=' characters in option directives. The modprobe lens has been updated and parsing no longer fails. (BZ#826752)

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

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

The Red Hat Security Response Team 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.

Libguestfs is a library and set of tools for accessing and modifying guest disk images.

It was found that guestfish, which enables shell scripting and command line access to libguestfs, insecurely created the temporary directory used to store the network socket when started in server mode. A local attacker could use this flaw to intercept and modify other user's guestfish command, allowing them to perform arbitrary guestfish actions with the privileges of a different user, or use this flaw to obtain authentication credentials. (CVE-2013-4419)

This issue was discovered by Michael Scherer of the Red Hat Regional IT team.

These updated libguestfs packages include numerous bug fixes and enhancements. Space precludes documenting all of these changes in this advisory. Users are directed to the Red Hat Enterprise Linux 6.5 Technical Notes, linked to in the References, for information on the most significant of these changes.

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

Updated glibc packages that fix one security issue and one bug are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team 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 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.

Multiple integer overflow flaws, leading to heap-based buffer overflows, were found in glibc's memory allocator functions (pvalloc, valloc, and memalign). If an application used such a function, it could cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2013-4332)

This update also fixes the following bug :

* Prior to this update, the size of the L3 cache in certain CPUs for SMP (Symmetric Multiprocessing) servers was not correctly detected.
The incorrect cache size detection resulted in less than optimal performance for routines that used this information, including the memset() function. To fix this bug, the cache size detection has been corrected and core routines including memset() have their performance restored to expected levels. (BZ#1011424)

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

An updated sudo package that fixes multiple security issues and several bugs is now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team 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 sudo (superuser do) utility allows system administrators to give certain users the ability to run commands as root.

A flaw was found in the way sudo handled time stamp files. An attacker able to run code as a local user and with the ability to control the system clock could possibly gain additional privileges by running commands that the victim user was allowed to run via sudo, without knowing the victim's password. (CVE-2013-1775)

It was found that sudo did not properly validate the controlling terminal device when the tty_tickets option was enabled in the /etc/sudoers file. An attacker able to run code as a local user could possibly gain additional privileges by running commands that the victim user was allowed to run via sudo, without knowing the victim's password. (CVE-2013-1776, CVE-2013-2776)

This update also fixes the following bugs :

* Due to a bug in the cycle detection algorithm of the visudo utility, visudo incorrectly evaluated certain alias definitions in the /etc/sudoers file as cycles. Consequently, a warning message about undefined aliases appeared. This bug has been fixed, /etc/sudoers is now parsed correctly by visudo and the warning message no longer appears. (BZ#849679)

* Previously, the 'sudo -l' command did not parse the /etc/sudoers file correctly if it contained an Active Directory (AD) group. The file was parsed only up to the first AD group information and then the parsing failed with the following message :

sudo: unable to cache group ADDOM\admingroup, already exists

With this update, the underlying code has been modified and 'sudo -l' now parses /etc/sudoers containing AD groups correctly. (BZ#855836)

* Previously, the sudo utility did not escape the backslash characters contained in user names properly. Consequently, if a system used sudo integrated with LDAP or Active Directory (AD) as the primary authentication mechanism, users were not able to authenticate on that system. With this update, sudo has been modified to process LDAP and AD names correctly and the authentication process now works as expected. (BZ#869287)

* Prior to this update, the 'visudo -s (strict)' command incorrectly parsed certain alias definitions. Consequently, an error message was issued. The bug has been fixed, and parsing errors no longer occur when using 'visudo

* s'. (BZ#905624)

All sudo users are advised to upgrade to this updated package, which contains backported patches to correct these issues.

Updated kernel packages that fix one security issue, several bugs, and add various enhancements are now available as part of the ongoing support and maintenance of Red Hat Enterprise Linux version 5. This is the tenth regular update.

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

This update fixes the following security issue :

* It was found that a deadlock could occur in the Out of Memory (OOM) killer. A process could trigger this deadlock by consuming a large amount of memory, and then causing request_module() to be called. A local, unprivileged user could use this flaw to cause a denial of service (excessive memory consumption). (CVE-2012-4398, Moderate)

Red Hat would like to thank Tetsuo Handa for reporting this issue.

This update also fixes numerous bugs and adds various enhancements.
Refer to the Red Hat Enterprise Linux 5.10 Release Notes for information on the most significant of these changes, and the Technical Notes for further information, both linked to in the References.

An updated ccid package that fixes one security issue and one bug is now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team 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.

Chip/Smart Card Interface Devices (CCID) is a USB smart card reader standard followed by most modern smart card readers. The ccid package provides a Generic, USB-based CCID driver for readers, which follow this standard.

An integer overflow, leading to an array index error, was found in the way the CCID driver processed a smart card's serial number. A local attacker could use this flaw to execute arbitrary code with the privileges of the user running the PC/SC Lite pcscd daemon (root, by default), by inserting a specially crafted smart card. (CVE-2010-4530)

This update also fixes the following bug :

* The pcscd service failed to read from the SafeNet Smart Card 650 v1 when it was inserted into a smart card reader. The operation failed with a 'IFDHPowerICC() PowerUp failed' error message. This was due to the card taking a long time to respond with a full Answer To Reset (ATR) request, which lead to a timeout, causing the card to fail to power up. This update increases the timeout value so that the aforementioned request is processed properly, and the card is powered on as expected. (BZ#907821)

All ccid users are advised to upgrade to this updated package, which contains backported patches to correct these issues.

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

The Red Hat Security Response Team 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.

SSSD (System Security Services Daemon) provides a set of daemons to manage access to remote directories and authentication mechanisms. It provides NSS (Name Service Switch) and PAM (Pluggable Authentication Modules) interfaces toward the system and a pluggable back end system to connect to multiple different account sources.

A race condition was found in the way SSSD copied and removed user home directories. A local attacker who is able to write into the home directory of a different user who is being removed could use this flaw to perform symbolic link attacks, possibly allowing them to modify and delete arbitrary files with the privileges of the root user.
(CVE-2013-0219)

The CVE-2013-0219 issue war discovered by Florian Weimer of the Red Hat Product Security Team.

This update also fixes the following bugs :

* After a paging control was used, memory in the sssd_be process was never freed which led to the growth of the sssd_be process memory usage over time. To fix this bug, the paging control was deallocated after use, and thus the memory usage of the sssd_be process no longer grows. (BZ#820908)

* If the sssd_be process was terminated and recreated while there were authentication requests pending, the sssd_pam process did not recover correctly and did not reconnect to the new sssd_be process.
Consequently, the sssd_pam process was seemingly blocked and did not accept any new authentication requests. The sssd_pam process has been fixes so that it reconnects to the new instance of the sssd_be process after the original one terminated unexpectedly. Even after a crash and reconnect, the sssd_pam process now accepts new authentication requests. (BZ#882414)

* When the sssd_be process hung for a while, it was terminated and a new instance was created. If the old instance did not respond to the TERM signal and continued running, SSSD terminated unexpectedly. As a consequence, the user could not log in. SSSD now keeps track of sssd_be subprocesses more effectively, making the restarts of sssd_be more reliable in such scenarios. Users can now log in whenever the sssd_be is restarted and becomes unresponsive. (BZ#886165)

* In case the processing of an LDAP request took longer than the client timeout upon completing the request (60 seconds by default), the PAM client could have accessed memory that was previously freed due to the client timeout being reached. As a result, the sssd_pam process terminated unexpectedly with a segmentation fault. SSSD now ignores an LDAP request result when it detects that the set timeout of this request has been reached. The sssd_pam process no longer crashes in the aforementioned scenario. (BZ#923813)

* When there was a heavy load of users and groups to be saved in cache, SSSD experienced a timeout. Consequently, NSS did not start the backup process properly and it was impossible to log in. A patch has been provided to fix this bug. The SSSD daemon now remains responsive and the login continues as expected. (BZ#805729)

* SSSD kept the file descriptors to the log files open. Consequently, on occasions like moving the actual log file and restarting the back end, SSSD still kept the file descriptors open. SSSD now closes the file descriptor after the child process execution; after a successful back end start, the file descriptor to log files is closed.
(BZ#961680)

* While performing access control in the Identity Management back end, SSSD erroneously downloaded the 'member' attribute from the server and then attempted to use it in the cache verbatim. Consequently, the cache attempted to use the 'member' attribute values as if they were pointing to the local cache which was CPU intensive. The member attribute when processing host groups is no longer downloaded and processed. Moreover, the login process is reasonably fast even with large host groups. (BZ#979047)

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

Updated samba3x packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team 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.

Samba is an open source implementation of the Server Message Block (SMB) or Common Internet File System (CIFS) protocol, which allows PC-compatible machines to share files, printers, and other information.

It was discovered that the Samba Web Administration Tool (SWAT) did not protect against being opened in a web page frame. A remote attacker could possibly use this flaw to conduct a clickjacking attack against SWAT users or users with an active SWAT session.
(CVE-2013-0213)

A flaw was found in the Cross-Site Request Forgery (CSRF) protection mechanism implemented in SWAT. An attacker with the knowledge of a victim's password could use this flaw to bypass CSRF protections and conduct a CSRF attack against the victim SWAT user. (CVE-2013-0214)

An integer overflow flaw was found in the way Samba handled an Extended Attribute (EA) list provided by a client. A malicious client could send a specially crafted EA list that triggered an overflow, causing the server to loop and reprocess the list using an excessive amount of memory. (CVE-2013-4124)

Note: This issue did not affect the default configuration of the Samba server.

Red Hat would like to thank the Samba project for reporting CVE-2013-0213 and CVE-2013-0214. Upstream acknowledges Jann Horn as the original reporter of CVE-2013-0213 and CVE-2013-0214.

All samba3x users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing this update, the smb service will be restarted automatically.

Updated php53 packages that fix multiple security issues, several bugs, and add one enhancement are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team 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.

PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server.

It was found that PHP did not properly handle file names with a NULL character. A remote attacker could possibly use this flaw to make a PHP script access unexpected files and bypass intended file system access restrictions. (CVE-2006-7243)

It was found that PHP did not check for carriage returns in HTTP headers, allowing intended HTTP response splitting protections to be bypassed. Depending on the web browser the victim is using, a remote attacker could use this flaw to perform HTTP response splitting attacks. (CVE-2011-1398)

A flaw was found in PHP's SSL client's hostname identity check when handling certificates that contain hostnames with NULL bytes. If an attacker was able to get a carefully crafted certificate signed by a trusted Certificate Authority, the attacker could use the certificate to conduct man-in-the-middle attacks to spoof SSL servers.
(CVE-2013-4248)

An integer signedness issue, leading to a heap-based buffer underflow, was found in the PHP scandir() function. If a remote attacker could upload an excessively large number of files to a directory the scandir() function runs on, it could cause the PHP interpreter to crash or, possibly, execute arbitrary code. (CVE-2012-2688)

It was found that PHP did not correctly handle the magic_quotes_gpc configuration directive. This could result in magic_quotes_gpc input escaping not being applied in all cases, possibly making it easier for a remote attacker to perform SQL injection attacks. (CVE-2012-0831)

It was found that the PHP SOAP parser allowed the expansion of external XML entities during SOAP message parsing. A remote attacker could possibly use this flaw to read arbitrary files that are accessible to a PHP application using a SOAP extension.
(CVE-2013-1643)

These updated php53 packages also include numerous bug fixes and enhancements. Space precludes documenting all of these changes in this advisory. Users are directed to the Red Hat Enterprise Linux 5.10 Technical Notes, linked to in the References, for information on the most significant of these changes.

All PHP users 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 daemon must be restarted for the update to take effect.

An updated xinetd package that fixes one security issue and two bugs is now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team 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 xinetd package provides a secure replacement for inetd, the Internet services daemon. xinetd provides access control for all services based on the address of the remote host and/or on time of access, and can prevent denial-of-access attacks.

When xinetd services are configured with the 'TCPMUX' or 'TCPMUXPLUS' type, and the tcpmux-server service is enabled, those services are accessible via port 1. It was found that enabling the tcpmux-server service (it is disabled by default) allowed every xinetd service, including those that are not configured with the 'TCPMUX' or 'TCPMUXPLUS' type, to be accessible via port 1. This could allow a remote attacker to bypass intended firewall restrictions.
(CVE-2012-0862)

Red Hat would like to thank Thomas Swan of FedEx for reporting this issue.

This update also fixes the following bugs :

* Prior to this update, a file descriptor array in the service.c source file was not handled as expected. As a consequence, some of the descriptors remained open when xinetd was under heavy load.
Additionally, the system log was filled with a large number of messages that took up a lot of disk space over time. This update modifies the xinetd code to handle the file descriptors correctly and messages no longer fill the system log. (BZ#852274)

* Prior to this update, services were disabled permanently when their CPS limit was reached. As a consequence, a failed bind operation could occur when xinetd attempted to restart the service. This update adds additional logic that attempts to restart the service. Now, the service is only disabled if xinetd cannot restart the service after 30 attempts. (BZ#811000)

All users of xinetd are advised to upgrade to this updated package, which contains backported patches to correct these issues.

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

Security fixes :

* A race condition flaw was found in the way the Linux kernel's KVM subsystem handled PIT (Programmable Interval Timer) emulation. A guest user who has access to the PIT I/O ports could use this flaw to crash the host. (CVE-2014-3611, Important)

* A NULL pointer dereference flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation handled simultaneous connections between the same hosts. A remote attacker could use this flaw to crash the system. (CVE-2014-5077, Important)

* It was found that the Linux kernel's KVM subsystem did not handle the VM exits gracefully for the invept (Invalidate Translations Derived from EPT) and invvpid (Invalidate Translations Based on VPID) instructions. On hosts with an Intel processor and invept/invppid VM exit support, an unprivileged guest user could use these instructions to crash the guest. (CVE-2014-3645, CVE-2014-3646, Moderate)

* A use-after-free flaw was found in the way the Linux kernel's Advanced Linux Sound Architecture (ALSA) implementation handled user controls. A local, privileged user could use this flaw to crash the system. (CVE-2014-4653, Moderate)

Red Hat would like to thank Lars Bull of Google for reporting CVE-2014-3611, and the Advanced Threat Research team at Intel Security for reporting CVE-2014-3645 and CVE-2014-3646.

Bug fixes :

* A known issue that could prevent Chelsio adapters using the cxgb4 driver from being initialized on IBM POWER8 systems has been fixed.
These adapters can now be used on IBM POWER8 systems as expected.
(BZ#1130548)

* When bringing a hot-added CPU online, the kernel did not initialize a CPU mask properly, which could result in a kernel panic. This update corrects the bug by ensuring that the CPU mask is properly initialized and the correct NUMA node selected. (BZ#1134715)

* The kernel could fail to bring a CPU online if the hardware supported both, the acpi-cpufreq and intel_pstate modules. This update ensures that the acpi-cpufreq module is not loaded in the intel_pstate module is loaded. (BZ#1134716)

* Due to a bug in the time accounting of the kernel scheduler, a divide error could occur when hot adding a CPU. To fix this problem, the kernel scheduler time accounting has been reworked. (BZ#1134717)

* The kernel did not handle exceptions caused by an invalid floating point control (FPC) register, resulting in a kernel oops. This problem has been fixed by placing the label to handle these exceptions to the correct place in the code. (BZ#1138733)

* A previous change to the kernel for the PowerPC architecture changed implementation of the compat_sys_sendfile() function. Consequently, the 64-bit sendfile() system call stopped working for files larger than 2 GB on PowerPC. This update restores previous behavior of sendfile() on PowerPC, and it again process files bigger than 2 GB as expected. (BZ#1139126)

* Previously, the kernel scheduler could schedule a CPU topology update even though the topology did not change. This could negatively affect the CPU load balancing, cause degradation of the system performance, and eventually result in a kernel oops. This problem has been fixed by skipping the CPU topology update if the topology has not actually changed. (BZ#1140300)

* Previously, recovery of a double-degraded RAID6 array could, under certain circumstances, result in data corruption. This could happen because the md driver was using an optimization that is safe to use only for single-degraded arrays. This update ensures that this optimization is skipped during the recovery of double-degraded RAID6 arrays. (BZ#1143850)

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.

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

Updated libvirt packages that fix two security issues and one bug are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate security impact. 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 libvirt library is a C API for managing and interacting with the virtualization capabilities of Linux and other operating systems. In addition, libvirt provides tools for remote management of virtualized systems.

An out-of-bounds read flaw was found in the way libvirt's qemuDomainGetBlockIoTune() function looked up the disk index in a non-persistent (live) disk configuration while a persistent disk configuration was being indexed. A remote attacker able to establish a read-only connection to libvirtd could use this flaw to crash libvirtd or, potentially, leak memory from the libvirtd process.
(CVE-2014-3633)

A denial of service flaw was found in the way libvirt's virConnectListAllDomains() function computed the number of used domains. A remote attacker able to establish a read-only connection to libvirtd could use this flaw to make any domain operations within libvirt unresponsive. (CVE-2014-3657)

The CVE-2014-3633 issue was discovered by Luyao Huang of Red Hat.

This update also fixes the following bug :

* Prior to this update, libvirt was setting the cpuset.mems parameter for domains with numatune/memory[nodeset] prior to starting them. As a consequence, domains with such a nodeset, which excluded the NUMA node with DMA and DMA32 zones (found in /proc/zoneinfo), could not be started due to failed KVM initialization. With this update, libvirt sets the cpuset.mems parameter after the initialization, and domains with any nodeset (in /numatune/memory) can be started without an error. (BZ#1135871)

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

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.

PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server. PHP's fileinfo module provides functions used to identify a particular file according to the type of data contained by the file.

A buffer overflow flaw was found in the way the File Information (fileinfo) extension processed certain Pascal strings. A remote attacker able to make a PHP application using fileinfo convert a specially crafted Pascal string provided by an image file could cause that application to crash. (CVE-2014-3478)

Multiple flaws were found in the File Information (fileinfo) extension regular expression rules for detecting various files. A remote attacker could use either of these flaws to cause a PHP application using fileinfo to consume an excessive amount of CPU. (CVE-2014-3538)

It was found that the fix for CVE-2012-1571 was incomplete; the File Information (fileinfo) extension did not correctly parse certain Composite Document Format (CDF) files. A remote attacker could use this flaw to crash a PHP application using fileinfo via a specially crafted CDF file. (CVE-2014-3587)

It was found that PHP's gd extension did not properly handle file names with a null character. A remote attacker could possibly use this flaw to make a PHP application access unexpected files and bypass intended file system access restrictions. (CVE-2014-5120)

A NULL pointer dereference flaw was found in the gdImageCreateFromXpm() function of PHP's gd extension. A remote attacker could use this flaw to crash a PHP application using gd via a specially crafted X PixMap (XPM) file. (CVE-2014-2497)

Multiple buffer over-read flaws were found in the php_parserr() function of PHP. A malicious DNS server or a man-in-the-middle attacker could possibly use this flaw to execute arbitrary code as the PHP interpreter if a PHP application used the dns_get_record() function to perform a DNS query. (CVE-2014-3597)

Two use-after-free flaws were found in the way PHP handled certain Standard PHP Library (SPL) Iterators and ArrayIterators. A malicious script author could possibly use either of these flaws to disclose certain portions of server memory. (CVE-2014-4670, CVE-2014-4698)

The CVE-2014-3478 issue was discovered by Francisco Alonso of Red Hat Product Security, the CVE-2014-3538 issue was discovered by Jan Kaluza of the Red Hat Web Stack Team, and the CVE-2014-3597 issue was discovered by David Kutalek of the Red Hat BaseOS QE.

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.

Updated php53 and php packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5 and 6 respectively.

Network Security Services (NSS) is a set of libraries designed to support the cross-platform development of security-enabled client and server applications.

A flaw was found in the way TLS False Start was implemented in NSS. An attacker could use this flaw to potentially return unencrypted information from the server. (CVE-2013-1740)

A race condition was found in the way NSS implemented session ticket handling as specified by RFC 5077. An attacker could use this flaw to crash an application using NSS or, in rare cases, execute arbitrary code with the privileges of the user running that application.
(CVE-2014-1490)

It was found that NSS accepted weak Diffie-Hellman Key exchange (DHKE) parameters. This could possibly lead to weak encryption being used in communication between the client and the server. (CVE-2014-1491)

An out-of-bounds write flaw was found in NSPR. A remote attacker could potentially use this flaw to crash an application using NSPR or, possibly, execute arbitrary code with the privileges of the user running that application. This NSPR flaw was not exposed to web content in any shipped version of Firefox. (CVE-2014-1545)

It was found that the implementation of Internationalizing Domain Names in Applications (IDNA) hostname matching in NSS did not follow the RFC 6125 recommendations. This could lead to certain invalid certificates with international characters to be accepted as valid.
(CVE-2014-1492)

Red Hat would like to thank the Mozilla project for reporting the CVE-2014-1490, CVE-2014-1491, and CVE-2014-1545 issues. Upstream acknowledges Brian Smith as the original reporter of CVE-2014-1490, Antoine Delignat-Lavaud and Karthikeyan Bhargavan as the original reporters of CVE-2014-1491, and Abhishek Arya as the original reporter of CVE-2014-1545.

The nss and nspr packages have been upgraded to upstream version 3.16.1 and 4.10.6 respectively, which provide a number of bug fixes and enhancements over the previous versions. (BZ#1110857, BZ#1110860)

This update also fixes the following bugs :

* Previously, when the output.log file was not present on the system, the shell in the Network Security Services (NSS) specification handled test failures incorrectly as false positive test results.
Consequently, certain utilities, such as 'grep', could not handle failures properly. This update improves error detection in the specification file, and 'grep' and other utilities now handle missing files or crashes as intended. (BZ#1035281)

* Prior to this update, a subordinate Certificate Authority (CA) of the ANSSI agency incorrectly issued an intermediate certificate installed on a network monitoring device. As a consequence, the monitoring device was enabled to act as an MITM (Man in the Middle) proxy performing traffic management of domain names or IP addresses that the certificate holder did not own or control. The trust in the intermediate certificate to issue the certificate for an MITM device has been revoked, and such a device can no longer be used for MITM attacks. (BZ#1042684)

* Due to a regression, MD5 certificates were rejected by default because Network Security Services (NSS) did not trust MD5 certificates. With this update, MD5 certificates are supported in Red Hat Enterprise Linux 5. (BZ#11015864)

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

Updated krb5 packages that fix multiple security issues and two bugs are now available for Red Hat Enterprise Linux 5.

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

Kerberos is an authentication system which allows clients and services to authenticate to each other with the help of a trusted third party, a Kerberos Key Distribution Center (KDC).

It was found that if a KDC served multiple realms, certain requests could cause the setup_server_realm() function to dereference a NULL pointer. A remote, unauthenticated attacker could use this flaw to crash the KDC using a specially crafted request. (CVE-2013-1418, CVE-2013-6800)

A NULL pointer dereference flaw was found in the MIT Kerberos SPNEGO acceptor for continuation tokens. A remote, unauthenticated attacker could use this flaw to crash a GSSAPI-enabled server application.
(CVE-2014-4344)

A buffer over-read flaw was found in the way MIT Kerberos handled certain requests. A man-in-the-middle attacker with a valid Kerberos ticket who is able to inject packets into a client or server application's GSSAPI session could use this flaw to crash the application. (CVE-2014-4341)

This update also fixes the following bugs :

* Prior to this update, the libkrb5 library occasionally attempted to free already freed memory when encrypting credentials. As a consequence, the calling process terminated unexpectedly with a segmentation fault. With this update, libkrb5 frees memory correctly, which allows the credentials to be encrypted appropriately and thus prevents the mentioned crash. (BZ#1004632)

* Previously, when the krb5 client library was waiting for a response from a server, the timeout variable in certain cases became a negative number. Consequently, the client could enter a loop while checking for responses. With this update, the client logic has been modified and the described error no longer occurs. (BZ#1089732)

All krb5 users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, the krb5kdc daemon will be restarted automatically.

Updated bind97 packages that fix one security issue and one bug are now available for Red Hat Enterprise Linux 5.

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 Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS) protocols. It contains a DNS server (named), a resolver library with routines for applications to use when interfacing with DNS, and tools for verifying that the DNS server is operating correctly. These packages contain version 9.7 of the BIND suite.

A denial of service flaw was found in the way BIND handled queries for NSEC3-signed zones. A remote attacker could use this flaw against an authoritative name server that served NCES3-signed zones by sending a specially crafted query, which, when processed, would cause named to crash. (CVE-2014-0591)

Note: The CVE-2014-0591 issue does not directly affect the version of bind97 shipped in Red Hat Enterprise Linux 5. This issue is being addressed however to assure it is not introduced in future builds of bind97 (possibly built with a different compiler or C library optimization).

This update also fixes the following bug :

* Previously, the bind97 initscript did not check for the existence of the ROOTDIR variable when shutting down the named daemon. As a consequence, some parts of the file system that are mounted when using bind97 in a chroot environment were unmounted on daemon shut down, even if bind97 was not running in a chroot environment. With this update, the initscript has been fixed to check for the existence of the ROOTDIR variable when unmounting some parts of the file system on named daemon shut down. Now, when shutting down bind97 that is not running in a chroot environment, no parts of the file system are unmounted. (BZ#1059118)

All bind97 users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing the update, the BIND daemon (named) will be restarted automatically.

An updated automake package that fixes one security issue is now available for Red Hat Enterprise Linux 5.

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.

Automake is a tool for automatically generating Makefile.in files compliant with the GNU Coding Standards.

It was found that the distcheck rule in Automake-generated Makefiles made a directory world-writable when preparing source archives. If a malicious, local user could access this directory, they could execute arbitrary code with the privileges of the user running 'make distcheck'. (CVE-2012-3386)

Red Hat would like to thank Jim Meyering for reporting this issue.
Upstream acknowledges Stefano Lattarini as the original reporter.

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

The Conga project is a management system for remote workstations. It consists of luci, which is a secure web-based front end, and ricci, which is a secure daemon that dispatches incoming messages to underlying management modules.

It was discovered that Plone, included as a part of luci, did not properly protect the administrator interface (control panel). A remote attacker could use this flaw to inject a specially crafted Python statement or script into Plone's restricted Python sandbox that, when the administrator interface was accessed, would be executed with the privileges of that administrator user. (CVE-2012-5485)

It was discovered that Plone, included as a part of luci, did not properly sanitize HTTP headers provided within certain URL requests. A remote attacker could use a specially crafted URL that, when processed, would cause the injected HTTP headers to be returned as a part of the Plone HTTP response, potentially allowing the attacker to perform other more advanced attacks. (CVE-2012-5486)

Multiple information leak flaws were found in the way conga processed luci site extension-related URL requests. A remote, unauthenticated attacker could issue a specially crafted HTTP request that, when processed, would result in unauthorized information disclosure.
(CVE-2013-6496)

It was discovered that various components in the luci site extension-related URLs were not properly restricted to administrative users. A remote, authenticated attacker could escalate their privileges to perform certain actions that should be restricted to administrative users, such as adding users and systems, and viewing log data. (CVE-2014-3521)

It was discovered that Plone, included as a part of luci, did not properly protect the privilege of running RestrictedPython scripts. A remote attacker could use a specially crafted URL that, when processed, would allow the attacker to submit and perform expensive computations or, in conjunction with other attacks, be able to access or alter privileged information. (CVE-2012-5488)

It was discovered that Plone, included as a part of luci, did not properly enforce permissions checks on the membership database. A remote attacker could use a specially crafted URL that, when processed, could allow the attacker to enumerate user account names.
(CVE-2012-5497)

It was discovered that Plone, included as a part of luci, did not properly handle the processing of requests for certain collections. A remote attacker could use a specially crafted URL that, when processed, would lead to excessive I/O and/or cache resource consumption. (CVE-2012-5498)

It was discovered that Plone, included as a part of luci, did not properly handle the processing of very large values passed to an internal utility function. A remote attacker could use a specially crafted URL that, when processed, would lead to excessive memory consumption. (CVE-2012-5499)

It was discovered that Plone, included as a part of luci, allowed a remote anonymous user to change titles of content items due to improper permissions checks. (CVE-2012-5500)

The CVE-2014-3521 issue was discovered by Radek Steiger of Red Hat, and the CVE-2013-6496 issue was discovered by Jan Pokorny of Red Hat.

The GNU Bourne Again shell (Bash) is a shell and command language interpreter compatible with the Bourne shell (sh). Bash is the default shell for Red Hat Enterprise Linux.

It was found that the fix for CVE-2014-6271 was incomplete, and Bash still allowed certain characters to be injected into other environments via specially crafted environment variables. An attacker could potentially use this flaw to override or bypass environment restrictions to execute shell commands. Certain services and applications allow remote unauthenticated attackers to provide environment variables, allowing them to exploit this issue.
(CVE-2014-7169)

Applications which directly create bash functions as environment variables need to be made aware of changes to the way names are handled by this update. For more information see the Knowledgebase article at https://access.redhat.com/articles/1200223

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

* An out-of-bounds memory access flaw was found in the Linux kernel's system call auditing implementation. On a system with existing audit rules defined, a local, unprivileged user could use this flaw to leak kernel memory to user space or, potentially, crash the system.
(CVE-2014-3917, Moderate)

This update also fixes the following bugs :

* A bug in the mtip32xx driver could prevent the Micron P420m PCIe SSD devices with unaligned I/O access from completing the submitted I/O requests. This resulted in a livelock situation and rendered the Micron P420m PCIe SSD devices unusable. To fix this problem, mtip32xx now checks whether an I/O access is unaligned and if so, it uses the correct semaphore. (BZ#1125776)

* A series of patches has been backported to improve the functionality of a touch pad on the latest Lenovo laptops in Red Hat Enterprise Linux 7. (BZ#1122559)

* Due to a bug in the bnx2x driver, a network adapter could be unable to recover from EEH error injection. The network adapter had to be taken offline and rebooted in order to function properly again. With this update, the bnx2x driver has been corrected and network adapters now recover from EEH errors as expected. (BZ#1107722)

* Previously, if an hrtimer interrupt was delayed, all future pending hrtimer events that were queued on the same processor were also delayed until the initial hrtimer event was handled. This could cause all hrtimer processing to stop for a significant period of time. To prevent this problem, the kernel has been modified to handle all expired hrtimer events when handling the initially delayed hrtimer event. (BZ#1113175)

* A previous change to the nouveau driver introduced a bit shift error, which resulted in a wrong display resolution being set with some models of NVIDIA controllers. With this update, the erroneous code has been corrected, and the affected NVIDIA controllers can now set the correct display resolution. (BZ#1114869)

* Due to a NULL pointer dereference bug in the be2net driver, the system could experience a kernel oops and reboot when disabling a network adapter after a permanent failure. This problem has been fixed by introducing a flag to keep track of the setup state. The failing adapter can now be disabled successfully without a kernel crash.
(BZ#1122558)

* Previously, the Huge Translation Lookaside Buffer (HugeTLB) allowed access to huge pages access by default. However, huge pages may be unsupported in some environments, such as a KVM guest on a PowerPC architecture, and an attempt to access a huge page in memory would result in a kernel oops. This update ensures that HugeTLB denies access to huge pages if the huge pages are not supported on the system. (BZ#1122115)

* If an NVMe device becomes ready but fails to create I/O queues, the nvme driver creates a character device handle to manage such a device.
Previously, a character device could be created before a device reference counter was initialized, which resulted in a kernel oops.
This problem has been fixed by calling the relevant initialization function earlier in the code. (BZ#1119720)

* On some firmware versions of the BladeEngine 3 (BE3) controller, interrupts remain disabled after a hardware reset. This was a problem for all Emulex-based network adapters using such a BE3 controller because these adapters would fail to recover from an EEH error if it occurred. To resolve this problem, the be2net driver has been modified to enable the interrupts in the eeh_resume handler explicitly.
(BZ#1121712)

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.
