The xen packages contain administration tools and the xend service for managing the kernel-xen kernel for virtualization on Red Hat Enterprise Linux.

A flaw was found in the way QEMU emulated the e1000 network interface card when the host was configured to accept jumbo network frames, and a fully-virtualized guest using the e1000 emulated driver was not. A remote attacker could use this flaw to crash the guest or, potentially, execute arbitrary code with root privileges in the guest.
(CVE-2012-6075)

All users of xen are advised to upgrade to these updated packages, which correct this issue. After installing the updated packages, all running fully-virtualized guests must be restarted for this update to take effect.

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

This update fixes the following security issues :

* Buffer overflow flaws were found in the udf_load_logicalvol() function in the Universal Disk Format (UDF) file system implementation in the Linux kernel. An attacker with physical access to a system could use these flaws to cause a denial of service or escalate their privileges. (CVE-2012-3400, Low)

This update also fixes the following bugs :

* Previously, race conditions could sometimes occur in interrupt handling on the Emulex BladeEngine 2 (BE2) controllers, causing the network adapter to become unresponsive. This update provides a series of patches for the be2net driver, which prevents the race from occurring. The network cards using BE2 chipsets no longer hang due to incorrectly handled interrupt events. (BZ#884704)

* A boot-time memory allocation pool (the DMI heap) is used to keep the list of Desktop Management Interface (DMI) devices during the system boot. Previously, the size of the DMI heap was only 2048 bytes on the AMD64 and Intel 64 architectures and the DMI heap space could become easily depleted on some systems, such as the IBM System x3500 M2. A subsequent OOM failure could, under certain circumstances, lead to a NULL pointer entry being stored in the DMI device list.
Consequently, scanning of such a corrupted DMI device list resulted in a kernel panic. The boot-time memory allocation pool for the AMD64 and Intel 64 architectures has been enlarged to 4096 bytes and the routines responsible for populating the DMI device list have been modified to skip entries if their name string is NULL. The kernel no longer panics in this scenario. (BZ#902683)

* The size of the buffer used to print the kernel taint output on kernel panic was too small, which resulted in the kernel taint output not being printed completely sometimes. With this update, the size of the buffer has been adjusted and the kernel taint output is now displayed properly. (BZ#905829)

* The code to print the kernel taint output contained a typographical error. Consequently, the kernel taint output, which is displayed on kernel panic, could not provide taint error messages for unsupported hardware. This update fixes the typo and the kernel taint output is now displayed correctly. (BZ#885063)

Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

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

It was discovered that OpenSSL leaked timing information when decrypting TLS/SSL and DTLS protocol encrypted records when CBC-mode cipher suites were used. A remote attacker could possibly use this flaw to retrieve plain text from the encrypted packets by using a TLS/SSL or DTLS server as a padding oracle. (CVE-2013-0169)

A NULL pointer dereference flaw was found in the OCSP response verification in OpenSSL. A malicious OCSP server could use this flaw to crash applications performing OCSP verification by sending a specially crafted response. (CVE-2013-0166)

It was discovered that the TLS/SSL protocol could leak information about plain text when optional compression was used. An attacker able to control part of the plain text sent over an encrypted TLS/SSL connection could possibly use this flaw to recover other portions of the plain text. (CVE-2012-4929)

Note: This update disables zlib compression, which was previously enabled in OpenSSL by default. Applications using OpenSSL now need to explicitly enable zlib compression to use it.

It was found that OpenSSL read certain environment variables even when used by a privileged (setuid or setgid) application. A local attacker could use this flaw to escalate their privileges. No application shipped with Red Hat Enterprise Linux 5 and 6 was affected by this problem. (BZ#839735)

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

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)

* A flaw was found in the way the KVM (Kernel-based Virtual Machine) subsystem handled guests attempting to run with the X86_CR4_OSXSAVE CPU feature flag set. On hosts without the XSAVE CPU feature, a local, unprivileged user could use this flaw to crash the host system. (The 'grep --color xsave /proc/cpuinfo' command can be used to verify if your system has the XSAVE CPU feature.) (CVE-2012-4461, Moderate)

* A memory disclosure flaw was found in the way the load_script() function in the binfmt_script binary format handler handled excessive recursions. A local, unprivileged user could use this flaw to leak kernel stack memory to user-space by executing specially crafted scripts. (CVE-2012-4530, Low)

Red Hat would like to thank Tetsuo Handa for reporting CVE-2012-4398, and Jon Howell for reporting CVE-2012-4461.

This update also fixes several bugs. Documentation for these changes will be available shortly from the Technical Notes document linked to in the References section.

Users should upgrade to these updated packages, which contain backported patches to correct these issues, and fix the bugs noted in the Technical Notes. The system must be rebooted for this update to take effect.

Updated mysql packages that fix several security issues 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.

MySQL is a multi-user, multi-threaded SQL database server. It consists of the MySQL server daemon (mysqld) and many client programs and libraries.

An updated xorg-x11-drv-qxl package that fixes one security issue is 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.

The xorg-x11-drv-qxl package provides an X11 video driver for the QEMU QXL video accelerator. This driver makes it possible to use Red Hat Enterprise Linux 6 as a guest operating system under the KVM kernel module and the QEMU multi-platform emulator, using the SPICE protocol.

A flaw was found in the way the host's qemu-kvm qxl driver and the guest's X.Org qxl driver interacted when a SPICE connection terminated. A user able to initiate a SPICE connection to a guest could use this flaw to make the guest temporarily unavailable or, potentially (if the sysctl kernel.softlockup_panic variable was set to '1' in the guest), crash the guest. (CVE-2013-0241)

All users of xorg-x11-drv-qxl are advised to upgrade to this updated package, which contains a backported patch to correct this issue. All running X.Org server instances using the qxl driver must be restarted for this update to take effect.

Updated mingw32-libxml2 packages that fix several security issues are now available for Red Hat Enterprise Linux 6. This advisory also contains information about future updates for the mingw32 packages, as well as the deprecation of the packages with the release of Red Hat Enterprise Linux 6.4.

The Red Hat Security Response Team 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.

These packages provide the libxml2 library, a development toolbox providing the implementation of various XML standards, for users of MinGW (Minimalist GNU for Windows).

IMPORTANT NOTE: The mingw32 packages in Red Hat Enterprise Linux 6 will no longer be updated proactively and will be deprecated with the release of Red Hat Enterprise Linux 6.4. These packages were provided to support other capabilities in Red Hat Enterprise Linux and were not intended for direct customer use. Customers are advised to not use these packages with immediate effect. Future updates to these packages will be at Red Hat's discretion and these packages may be removed in a future minor release.

A heap-based buffer overflow flaw was found in the way libxml2 decoded entity references with long names. A remote attacker could provide a specially crafted XML file that, when opened in an application linked against libxml2, would cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2011-3919)

A heap-based buffer underflow flaw was found in the way libxml2 decoded certain entities. A remote attacker could provide a specially crafted XML file that, when opened in an application linked against libxml2, would cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2012-5134)

It was found that the hashing routine used by libxml2 arrays was susceptible to predictable hash collisions. Sending a specially crafted message to an XML service could result in longer processing time, which could lead to a denial of service. To mitigate this issue, randomization has been added to the hashing function to reduce the chance of an attacker successfully causing intentional collisions.
(CVE-2012-0841)

Multiple flaws were found in the way libxml2 parsed certain XPath (XML Path Language) expressions. If an attacker were able to supply a specially crafted XML file to an application using libxml2, as well as an XPath expression for that application to run against the crafted file, it could cause the application to crash. (CVE-2010-4008, CVE-2010-4494, CVE-2011-2821, CVE-2011-2834)

Two heap-based buffer overflow flaws were found in the way libxml2 decoded certain XML files. A remote attacker could provide a specially crafted XML file that, when opened in an application linked against libxml2, would cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2011-0216, CVE-2011-3102)

An integer overflow flaw, leading to a heap-based buffer overflow, was found in the way libxml2 parsed certain XPath expressions. If an attacker were able to supply a specially crafted XML file to an application using libxml2, as well as an XPath expression for that application to run against the crafted file, it could cause the application to crash or, possibly, execute arbitrary code.
(CVE-2011-1944)

An out-of-bounds memory read flaw was found in libxml2. A remote attacker could provide a specially crafted XML file that, when opened in an application linked against libxml2, would cause the application to crash. (CVE-2011-3905)

Red Hat would like to thank the Google Security Team for reporting the CVE-2010-4008 issue. Upstream acknowledges Bui Quang Minh from Bkis as the original reporter of CVE-2010-4008.

All users of mingw32-libxml2 are advised to upgrade to these updated packages, which contain backported patches to correct these issues.

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

FreeType is a free, high-quality, portable font engine that can open and manage font files. It also loads, hints, and renders individual glyphs efficiently.

A flaw was found in the way the FreeType font rendering engine processed certain Glyph Bitmap Distribution Format (BDF) fonts. If a user loaded a specially crafted font file with an application linked against FreeType, it could cause the application to crash or, possibly, execute arbitrary code with the privileges of the user running the application. (CVE-2012-5669)

Users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. The X server must be restarted (log out, then log back in) for this update to take effect.

Updated abrt and libreport packages that fix two security issues are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team 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.

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

It was found that the /usr/libexec/abrt-action-install-debuginfo-to-abrt-cache tool did not sufficiently sanitize its environment variables. This could lead to Python modules being loaded and run from non-standard directories (such as /tmp/). A local attacker could use this flaw to escalate their privileges to that of the abrt user. (CVE-2012-5659)

A race condition was found in the way ABRT handled the directories used to store information about crashes. A local attacker with the privileges of the abrt user could use this flaw to perform a symbolic link attack, possibly allowing them to escalate their privileges to root. (CVE-2012-5660)

Red Hat would like to thank Martin Carpenter of Citco for reporting the CVE-2012-5660 issue. CVE-2012-5659 was discovered by Miloslav Trmac of Red Hat.

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

Updated nss, nss-util, and nspr packages that fix one security issue, various bugs, and add 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.

Network Security Services (NSS) is a set of libraries designed to support the cross-platform development of security-enabled client and server applications. Netscape Portable Runtime (NSPR) provides platform independence for non-GUI operating system facilities.

It was found that a Certificate Authority (CA) mis-issued two intermediate certificates to customers. These certificates could be used to launch man-in-the-middle attacks. This update renders those certificates as untrusted. This covers all uses of the certificates, including SSL, S/MIME, and code signing. (BZ#890605)

Note: This fix only applies to applications using the NSS Builtin Object Token. It does not render the certificates untrusted for applications that use the NSS library, but do not use the NSS Builtin Object Token.

In addition, the nss package has been upgraded to upstream version 3.13.6, the nss-util package has been upgraded to upstream version 3.13.6, and the nspr package has been upgraded to upstream version 4.9.2. These updates provide a number of bug fixes and enhancements over the previous versions. (BZ#891663, BZ#891670, BZ#891661)

Users of NSS, NSPR, and nss-util are advised to upgrade to these updated packages, which fix these issues and add these enhancements.
After installing this update, applications using NSS, NSPR, or nss-util must be restarted for this update to take effect.

Updated ipa packages that fix one security issue 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.

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

A weakness was found in the way IPA clients communicated with IPA servers when initially attempting to join IPA domains. As there was no secure way to provide the IPA server's Certificate Authority (CA) certificate to the client during a join, the IPA client enrollment process was susceptible to man-in-the-middle attacks. This flaw could allow an attacker to obtain access to the IPA server using the credentials provided by an IPA client, including administrative access to the entire domain if the join was performed using an administrator's credentials. (CVE-2012-5484)

Note: This weakness was only exposed during the initial client join to the realm, because the IPA client did not yet have the CA certificate of the server. Once an IPA client has joined the realm and has obtained the CA certificate of the IPA server, all further communication is secure. If a client were using the OTP (one-time password) method to join to the realm, an attacker could only obtain unprivileged access to the server (enough to only join the realm).

Red Hat would like to thank Petr Mensik for reporting this issue.

This update must be installed on both the IPA client and IPA server.
When this update has been applied to the client but not the server, ipa-client-install, in unattended mode, will fail if you do not have the correct CA certificate locally, noting that you must use the '--force' option to insecurely obtain the certificate. In interactive mode, the certificate will try to be obtained securely from LDAP. If this fails, you will be prompted to insecurely download the certificate via HTTP. In the same situation when using OTP, LDAP will not be queried and you will be prompted to insecurely download the certificate via HTTP.

Users of ipa are advised to upgrade to these updated packages, which correct this issue. After installing the update, changes in LDAP are handled by ipa-ldap-updater automatically and are effective immediately.

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

Updated mysql packages that fix two security issues are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team 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.

MySQL is a multi-user, multi-threaded SQL database server. It consists of the MySQL server daemon (mysqld) and many client programs and libraries.

A stack-based buffer overflow flaw was found in the user permission checking code in MySQL. An authenticated database user could use this flaw to crash the mysqld daemon or, potentially, execute arbitrary code with the privileges of the user running the mysqld daemon.
(CVE-2012-5611)

A flaw was found in the way MySQL calculated the key length when creating a sort order index for certain queries. An authenticated database user could use this flaw to crash the mysqld daemon.
(CVE-2012-2749)

This update also adds a patch for a potential flaw in the MySQL password checking function, which could allow an attacker to log into any MySQL account without knowing the correct password. This problem (CVE-2012-2122) only affected MySQL packages that use a certain compiler and C library optimization. It did not affect the mysql packages in Red Hat Enterprise Linux 5. The patch is being added as a preventive measure to ensure this problem cannot get exposed in future revisions of the mysql packages. (BZ#814605)

All MySQL users should upgrade to these updated packages, which correct these issues. After installing this update, the MySQL server daemon (mysqld) will be restarted automatically.

An updated vino package that fixes several security issues is 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.

Vino is a Virtual Network Computing (VNC) server for GNOME. It allows remote users to connect to a running GNOME session using VNC.

It was found that Vino transmitted all clipboard activity on the system running Vino to all clients connected to port 5900, even those who had not authenticated. A remote attacker who is able to access port 5900 on a system running Vino could use this flaw to read clipboard data without authenticating. (CVE-2012-4429)

Two out-of-bounds memory read flaws were found in the way Vino processed client framebuffer requests in certain encodings. An authenticated client could use these flaws to send a specially crafted request to Vino, causing it to crash. (CVE-2011-0904, CVE-2011-0905)

In certain circumstances, the vino-preferences dialog box incorrectly indicated that Vino was only accessible from the local network. This could confuse a user into believing connections from external networks are not allowed (even when they are allowed). With this update, vino-preferences no longer displays connectivity and reachable information. (CVE-2011-1164)

There was no warning that Universal Plug and Play (UPnP) was used to open ports on a user's network router when the 'Configure network automatically to accept connections' option was enabled (it is disabled by default) in the Vino preferences. This update changes the option's description to avoid the risk of a UPnP router configuration change without the user's consent. (CVE-2011-1165)

All Vino users should upgrade to this updated package, which contains backported patches to resolve these issues. The GNOME session must be restarted (log out, then log back in) for this update to take effect.

Updated kernel packages that fix three 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.

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

This update fixes the following security issues :

* It was found that the Xen hypervisor implementation did not perform range checking on the guest provided values in multiple hypercalls. A privileged guest user could use this flaw to trigger long loops, leading to a denial of service (Xen hypervisor hang). (CVE-2012-5515, Moderate)

* It was found that when running a 32-bit binary that uses a large number of shared libraries, one of the libraries would always be loaded at a predictable address in memory. An attacker could use this flaw to bypass the Address Space Layout Randomization (ASLR) security feature. (CVE-2012-1568, Low)

* A flaw was found in the way the Linux kernel's IPv6 implementation handled overlapping, fragmented IPv6 packets. A remote attacker could potentially use this flaw to bypass protection mechanisms (such as a firewall or intrusion detection system (IDS)) when sending network packets to a target system. (CVE-2012-4444, Low)

Red Hat would like to thank the Xen project for reporting CVE-2012-5515, and Antonios Atlasis working with Beyond Security's SecuriTeam Secure Disclosure program and Loganaden Velvindron of AFRINIC for reporting CVE-2012-4444.

This update also fixes several bugs. Space precludes documenting all of these changes in this advisory. Documentation for these changes will be available shortly from the Red Hat Enterprise Linux 5.9 Technical Notes document linked to in the References section.

Users should 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-1.7.0-openjdk packages that fix two security issues are now available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team 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.

These packages provide the OpenJDK 7 Java Runtime Environment and the OpenJDK 7 Software Development Kit.

Two improper permission check issues were discovered in the reflection API in OpenJDK. An untrusted Java application or applet could use these flaws to bypass Java sandbox restrictions. (CVE-2012-3174, CVE-2013-0422)

This erratum also upgrades the OpenJDK package to IcedTea7 2.3.4.
Refer to the NEWS file, linked to in the References, for further information.

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.

Updated gtk2 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.

GIMP Toolkit (GTK+) is a multi-platform toolkit for creating graphical user interfaces.

An integer overflow flaw was found in the X BitMap (XBM) image file loader in GTK+. A remote attacker could provide a specially crafted XBM image file that, when opened in an application linked against GTK+ (such as Nautilus), would cause the application to crash.
(CVE-2012-2370)

This update also fixes the following bugs :

* Due to a bug in the Input Method GTK+ module, the usage of the Taiwanese Big5 (zh_TW.Big-5) locale led to the unexpected termination of certain applications, such as the GDM greeter. The bug has been fixed, and the Taiwanese locale no longer causes applications to terminate unexpectedly. (BZ#487630)

* When a file was initially selected after the GTK+ file chooser dialog was opened and the Location field was visible, pressing the Enter key did not open the file. With this update, the initially selected file is opened regardless of the visibility of the Location field. (BZ#518483)

* When a file was initially selected after the GTK+ file chooser dialog was opened and the Location field was visible, pressing the Enter key did not change into the directory. With this update, the dialog changes into the initially selected directory regardless of the visibility of the Location field. (BZ#523657)

* Previously, the GTK Print dialog did not reflect the user-defined printer preferences stored in the ~/.cups/lpoptions file, such as those set in the Default Printer preferences panel. Consequently, the first device in the printer list was always set as a default printer.
With this update, the underlying source code has been enhanced to parse the option file. As a result, the default values in the print dialog are set to those previously specified by the user. (BZ#603809)

* The GTK+ file chooser did not properly handle saving of nameless files. Consequently, attempting to save a file without specifying a file name caused GTK+ to become unresponsive. With this update, an explicit test for this condition has been added into the underlying source code. As a result, GTK+ no longer hangs in the described scenario. (BZ#702342)

* When using certain graphics tablets, the GTK+ library incorrectly translated the input coordinates. Consequently, an offset occurred between the position of the pen and the content drawn on the screen.
This issue was limited to the following configuration: a Wacom tablet with input coordinates bound to a single monitor in a dual head configuration, drawing with a pen with the pressure sensitivity option enabled. With this update, the coordinate translation method has been changed, and the offset is no longer present in the described configuration. (BZ#743658)

* Previously, performing drag and drop operations on tabs in applications using the GtkNotebook widget could lead to releasing the same resource twice. Eventually, this behavior caused the applications to terminate with a segmentation fault. This bug has been fixed, and the applications using GtkNotebook no longer terminate in the aforementioned scenario. (BZ#830901)

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

Updated freeradius2 packages that fix one security issue and multiple 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.

FreeRADIUS is an open source Remote Authentication Dial-In User Service (RADIUS) server which allows RADIUS clients to perform authentication against the RADIUS server. The RADIUS server may optionally perform accounting of its operations using the RADIUS protocol.

It was found that the 'unix' module ignored the password expiration setting in '/etc/shadow'. If FreeRADIUS was configured to use this module for user authentication, this flaw could allow users with an expired password to successfully authenticate, even though their access should have been denied. (CVE-2011-4966)

This update also fixes the following bugs :

* After log rotation, the freeradius logrotate script failed to reload the radiusd daemon and log messages were lost. This update has added a command to the freeradius logrotate script to reload the radiusd daemon and the radiusd daemon re-initializes and reopens its log files after log rotation as expected. (BZ#787111)

* The radtest script with the 'eap-md5' option failed because it passed the IP family argument when invoking the radeapclient utility and the radeapclient utility did not recognize the IP family. The radeapclient utility now recognizes the IP family argument and radtest now works with eap-md5 as expected. (BZ#846476)

* Previously, freeradius was compiled without the '--with-udpfromto' option. Consequently, with a multihomed server and explicitly specifying the IP address, freeradius sent the reply with the wrong IP source address. With this update, freeradius has been built with the '--with-udpfromto' configuration option and the RADIUS reply is always sourced from the IP address the request was sent to. (BZ#846471)

* Due to invalid syntax in the PostgreSQL admin schema file, the FreeRADIUS PostgreSQL tables failed to be created. With this update, the syntax has been adjusted and the tables are created as expected.
(BZ#818885)

* FreeRADIUS has a thread pool that dynamically grows based on load.
If multiple threads using the 'rlm_perl()' function are spawned in quick succession, the FreeRADIUS server sometimes terminated unexpectedly with a segmentation fault due to parallel calls to the 'rlm_perl_clone()' function. With this update, a mutex for the threads has been added and the problem no longer occurs. (BZ#846475)

* The man page for 'rlm_dbm_parser' was incorrectly installed as 'rlm_dbm_parse', omitting the trailing 'r'. The man page now correctly appears as rlm_dbm_parser. (BZ#781877)

All users of freeradius2 are advised to upgrade to these updated packages, which contain backported patches to correct these issues.
They are also advised to check for RPM backup files ending in '.rpmnew' or '.rpmsave' under the /etc/raddb/ directory after the update because the FreeRADIUS server will attempt to load every file it finds in its configuration directory. The extra files will often cause the wrong configuration values to be applied resulting in either unpredictable behavior or the failure of the server to initialize and run.

Updated hplip3 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 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.

Hewlett-Packard Linux Imaging and Printing (HPLIP) provides drivers for Hewlett-Packard (HP) printers and multifunction peripherals.

It was found that the HP CUPS (Common UNIX Printing System) fax filter in HPLIP created a temporary file in an insecure way. A local attacker could use this flaw to perform a symbolic link attack, overwriting arbitrary files accessible to a process using the fax filter (such as the hp3-sendfax tool). (CVE-2011-2722)

This update also fixes the following bug :

* Previous modifications of the hplip3 package to allow it to be installed alongside the original hplip package introduced several problems to fax support; for example, the hp-sendfax utility could become unresponsive. These problems have been fixed with this update.
(BZ#501834)

All users of hplip3 are advised to upgrade to these updated packages, which contain backported patches to correct these issues.

An updated autofs package that fixes one security issue, several bugs, and adds one enhancement 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 autofs utility controls the operation of the automount daemon. The automount daemon automatically mounts and unmounts file systems.

A bug fix included in RHBA-2012:0264 introduced a denial of service flaw in autofs. When using autofs with LDAP, a local user could use this flaw to crash autofs, preventing future mount requests from being processed until the autofs service was restarted. Note: This flaw did not impact existing mounts (except for preventing mount expiration).
(CVE-2012-2697)

Red Hat would like to thank Ray Rocker for reporting this issue.

This update also fixes the following bugs :

* The autofs init script sometimes timed out waiting for the automount daemon to exit and returned a shutdown failure if the daemon failed to exit in time. To resolve this problem, the amount of time that the init script waits for the daemon has been increased to allow for cases where servers are slow to respond or there are many active mounts.
(BZ#585058)

* Due to an omission when backporting a change, autofs attempted to download the entire LDAP map at startup. This mistake has now been corrected. (BZ#767428)

* A function to check the validity of a mount location was meant to check only for a small subset of map location errors. A recent modification in error reporting inverted a logic test in this validating function. Consequently, the scope of the test was widened, which caused the automount daemon to report false positive failures.
With this update, the faulty logic test has been corrected and false positive failures no longer occur. (BZ#798448)

* When there were many attempts to access invalid or non-existent keys, the automount daemon used excessive CPU resources. As a consequence, systems sometimes became unresponsive. The code has been improved so that automount checks for invalid keys earlier in the process which has eliminated a significant amount of the processing overhead. (BZ#847101)

* The auto.master(5) man page did not document the '-t, --timeout' option in the FORMAT options section. This update adds this information to the man page. (BZ#859890)

This update also adds the following enhancement :

* Previously, it was not possible to configure separate timeout values for individual direct map entries in the autofs master map. This update adds this functionality. (BZ#690404)

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

Updated gnome-vfs2 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.

The gnome-vfs2 packages provide the GNOME Virtual File System, which is the foundation of the Nautilus file manager. neon is an HTTP and WebDAV client library embedded in the gnome-vfs2 packages.

A denial of service flaw was found in the neon Extensible Markup Language (XML) parser. Visiting a malicious DAV server with an application using gnome-vfs2 (such as Nautilus) could possibly cause the application to consume an excessive amount of CPU and memory.
(CVE-2009-2473)

This update also fixes the following bugs :

* When extracted from the Uniform Resource Identifier (URI), gnome-vfs2 returned escaped file paths. If a path, as stored in the URI, contained non-ASCII characters or ASCII characters which are parsed as something other than a file path (for example, spaces), the escaped path was inaccurate. Consequently, files with the described type of URI could not be processed. With this update, gnome-vfs2 properly unescapes paths that are required for a system call. As a result, these paths are parsed properly. (BZ#580855)

* In certain cases, the trash info file was populated by foreign entries, pointing to live data. Emptying the trash caused an accidental deletion of valuable data. With this update, a workaround has been applied in order to prevent the deletion. As a result, the accidental data loss is prevented, however further information is still gathered to fully fix this problem. (BZ#586015)

* Due to a wrong test checking for a destination file system, the Nautilus file manager failed to delete a symbolic link to a folder which was residing in another file system. With this update, a special test has been added. As a result, a symbolic link pointing to another file system can be trashed or deleted properly. (BZ#621394)

* Prior to this update, when directories without a read permission were marked for copy, the Nautilus file manager skipped these unreadable directories without notification. With this update, Nautilus displays an error message and properly informs the user about the aforementioned problem. (BZ#772307)

* Previously, gnome-vfs2 used the stat() function calls for every file on the MultiVersion File System (MVFS), used for example by IBM Rational ClearCase. This behavior significantly slowed down file operations. With this update, the unnecessary stat() operations have been limited. As a result, gnome-vfs2 user interfaces, such as Nautilus, are more responsive. (BZ#822817)

All gnome-vfs2 users are advised to upgrade to these updated packages, which contain backported patches to correct these issues.

Updated httpd packages that fix multiple security issues, various bugs, and add enhancements are 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 httpd packages contain the Apache HTTP Server (httpd), which is the namesake project of The Apache Software Foundation.

Input sanitization flaws were found in the mod_negotiation module. A remote attacker able to upload or create files with arbitrary names in a directory that has the MultiViews options enabled, could use these flaws to conduct cross-site scripting and HTTP response splitting attacks against users visiting the site. (CVE-2008-0455, CVE-2008-0456, CVE-2012-2687)

Bug fixes :

* Previously, no check was made to see if the /etc/pki/tls/private/localhost.key file was a valid key prior to running the '%post' script for the 'mod_ssl' package. Consequently, when /etc/pki/tls/certs/localhost.crt did not exist and 'localhost.key' was present but invalid, upgrading the Apache HTTP Server daemon (httpd) with mod_ssl failed. The '%post' script has been fixed to test for an existing SSL key. As a result, upgrading httpd with mod_ssl now proceeds as expected. (BZ#752618)

* The 'mod_ssl' module did not support operation under FIPS mode.
Consequently, when operating Red Hat Enterprise Linux 5 with FIPS mode enabled, httpd failed to start. An upstream patch has been applied to disable non-FIPS functionality if operating under FIPS mode and httpd now starts as expected. (BZ#773473)

* Prior to this update, httpd exit status codes were not Linux Standard Base (LSB) compliant. When the command 'service httpd reload' was run and httpd failed, the exit status code returned was '0' and not in the range 1 to 6 as expected. A patch has been applied to the init script and httpd now returns '1' as an exit status code.
(BZ#783242)

* Chunked Transfer Coding is described in RFC 2616. Previously, the Apache server did not correctly handle a chunked encoded POST request with a 'chunk-size' or 'chunk-extension' value of 32 bytes or more.
Consequently, when such a POST request was made the server did not respond. An upstream patch has been applied and the problem no longer occurs. (BZ#840845)

* Due to a regression, when mod_cache received a non-cacheable 304 response, the headers were served incorrectly. Consequently, compressed data could be returned to the client without the cached headers to indicate the data was compressed. An upstream patch has been applied to merge response and cached headers before data from the cache is served to the client. As a result, cached data is now correctly interpreted by the client. (BZ#845532)

* In a proxy configuration, certain response-line strings were not handled correctly. If a response-line without a 'description' string was received from the origin server, for a non-standard status code, such as the '450' status code, a '500 Internal Server Error' would be returned to the client. This bug has been fixed so that the original response line is returned to the client. (BZ#853128)

Enhancements :

* The configuration directive 'LDAPReferrals' is now supported in addition to the previously introduced 'LDAPChaseReferrals'.
(BZ#727342)

* The AJP support module for 'mod_proxy', 'mod_proxy_ajp', now supports the 'ProxyErrorOverride' directive. Consequently, it is now possible to configure customized error pages for web applications running on a backend server accessed via AJP. (BZ#767890)

* The '%posttrans' scriptlet which automatically restarts the httpd service after a package upgrade can now be disabled. If the file /etc/sysconfig/httpd-disable-posttrans exists, the scriptlet will not restart the daemon. (BZ#833042)

* The output of 'httpd -S' now includes configured alias names for each virtual host. (BZ#833043)

* New certificate variable names are now exposed by 'mod_ssl' using the '_DN_userID' suffix, such as 'SSL_CLIENT_S_DN_userID', which use the commonly used object identifier (OID) definition of 'userID', OID 0.9.2342.19200300.100.1.1. (BZ#840036)

All users of httpd are advised to upgrade to these updated packages, which fix these issues and add these enhancements.

Updated ruby packages that fix two security issues 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. 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.

Ruby is an extensible, interpreted, object-oriented, scripting language. It has features to process text files and to do system management tasks.

It was found that certain methods did not sanitize file names before passing them to lower layer routines in Ruby. If a Ruby application created files with names based on untrusted input, it could result in the creation of files with different names than expected.
(CVE-2012-4522)

It was found that the RHSA-2011:0909 update did not correctly fix the CVE-2011-1005 issue, a flaw in the method for translating an exception message into a string in the Exception class. A remote attacker could use this flaw to bypass safe level 4 restrictions, allowing untrusted (tainted) code to modify arbitrary, trusted (untainted) strings, which safe level 4 restrictions would otherwise prevent. (CVE-2012-4481)

The CVE-2012-4481 issue was discovered by Vit Ondruch of Red Hat.

This update also fixes the following bug :

* Prior to this update, the 'rb_syck_mktime' option could, under certain circumstances, terminate with a segmentation fault when installing libraries with certain gems. This update modifies the underlying code so that Ruby gems can be installed as expected.
(BZ#834381)

All users of Ruby are advised to upgrade to these updated packages, which contain backported patches to resolve these issues.

Updated conga packages that fix one security issue, multiple bugs, and add two enhancements 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.

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 luci stored usernames and passwords in session cookies. This issue prevented the session inactivity timeout feature from working correctly, and allowed attackers able to get access to a session cookie to obtain the victim's authentication credentials.
(CVE-2012-3359)

Red Hat would like to thank George Hedfors of Cybercom Sweden East AB for reporting this issue.

This update also fixes the following bugs :

* Prior to this update, luci did not allow the fence_apc_snmp agent to be configured. As a consequence, users could not configure or view an existing configuration for fence_apc_snmp. This update adds a new screen that allows fence_apc_snmp to be configured. (BZ#832181)

* Prior to this update, luci did not allow the SSL operation of the fence_ilo fence agent to be enabled or disabled. As a consequence, users could not configure or view an existing configuration for the 'ssl' attribute for fence_ilo. This update adds a checkbox to show whether the SSL operation is enabled and allows users to edit that attribute. (BZ#832183)

* Prior to this update, luci did not allow the 'identity_file' attribute of the fence_ilo_mp fence agent to be viewed or edited. As a consequence, users could not configure or view an existing configuration for the 'identity_file' attribute of the fence_ilo_mp fence agent. This update adds a text input box to show the current state of the 'identity_file' attribute of fence_ilo_mp and allows users to edit that attribute. (BZ#832185)

* Prior to this update, redundant files and directories remained on the file system at /var/lib/luci/var/pts and /usr/lib{,64}/luci/zope/var/pts when the luci package was uninstalled.
This update removes these files and directories when the luci package is uninstalled. (BZ#835649)

* Prior to this update, the 'restart-disable' recovery policy was not displayed in the recovery policy list from which users could select when they configure a recovery policy for a failover domain. As a consequence, the 'restart-disable' recovery policy could not be set with the luci GUI. This update adds the 'restart-disable' recovery option to the recovery policy pulldown list. (BZ#839732)

* Prior to this update, line breaks that were not anticipated in the 'yum list' output could cause package upgrade and/or installation to fail when creating clusters or adding nodes to existing clusters. As a consequence, creating clusters and adding cluster nodes to existing clusters could fail. This update modifies the ricci daemon to be able to correctly handle line breaks in the 'yum list' output. (BZ#842865)

In addition, this update adds the following enhancements :

* This update adds support for configuring the Intel iPDU fence agent to the luci package. (BZ#741986)

* This update adds support for viewing and changing the state of the new 'nfsrestart' attribute to the FS and Cluster FS resource agent configuration screens. (BZ#822633)

All users of conga are advised to upgrade to these updated packages, which resolve these issues and add these enhancements. After installing this update, the luci and ricci services will be restarted automatically.

Updated libvirt 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.

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.

Bus and device IDs were ignored when attempting to attach multiple USB devices with identical vendor or product IDs to a guest. This could result in the wrong device being attached to a guest, giving that guest root access to the device. (CVE-2012-2693)

This update also fixes the following bugs :

* Previously, the libvirtd library failed to set the autostart flags for already defined QEMU domains. This bug has been fixed, and the domains can now be successfully marked as autostarted. (BZ#675319)

* Prior to this update, the virFileAbsPath() function was not taking into account the slash ('/') directory separator when allocating memory for combining the cwd() function and a path. This behavior could lead to a memory corruption. With this update, a transformation to the virAsprintff() function has been introduced into virFileAbsPath(). As a result, the aforementioned behavior no longer occurs. (BZ#680289)

* With this update, a man page of the virsh user interface has been enhanced with information on the 'domxml-from-native' and 'domxml-to-native' commands. A correct notation of the format argument has been clarified. As a result, confusion is avoided when setting the format argument in the described commands. (BZ#783001)

All users of libvirt 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.

An updated squirrelmail package that fixes one security issue 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. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

SquirrelMail is a standards-based webmail package written in PHP.

The SquirrelMail security update RHSA-2012:0103 did not, unlike the erratum text stated, correct the CVE-2010-2813 issue, a flaw in the way SquirrelMail handled failed log in attempts. A user preference file was created when attempting to log in with a password containing an 8-bit character, even if the username was not valid. A remote attacker could use this flaw to eventually consume all hard disk space on the target SquirrelMail server. (CVE-2012-2124)

This update also fixes the following bugs :

* Prior to this update, SquirrelMail could not decode multi-line subjects properly. Consequently, the decode header internationalization option did not properly handle new lines or tabs at the beginning of the lines. This bug has been fixed and SquirrelMail now works correctly in the described scenario.
(BZ#241861)

* Due to a bug, attachments written in HTML code on the Windows operating system were not displayed properly when accessed with SquirrelMail; the '!=null' string was trimmed to '!ull'. This bug has been fixed and the attachments are now displayed correctly in such a case. (BZ#359791)

* Previously, e-mail messages with a Unique Identifier (UID) larger than 2^31 bytes were unreadable when using the squirrelmail package.
With this patch the squirrelmail package is able to read all messages regardless of the UIDs size. (BZ#450780)

* Due to a bug, a PHP script did not assign the proper character set to requested variables. Consequently, SquirrelMail could not display any e-mails. The underlying source code has been modified and now the squirrelmail package assigns the correct character set. (BZ#475188)

* Due to the incorrect internationalization option located at the i18n.php file, the squirrelmail package could not use the GB 2312 character set. The i18n.php file has been fixed and the GB 2312 character set works correctly in the described scenario. (BZ#508686)

* Previously, the preg_split() function contained a misspelled constant, PREG_SPLIT_NI_EMPTY, which could cause SquirrelMail to produce error messages. The name of the constant has been corrected to PREG_SPLIT_NO_EMPTY, and SquirrelMail no longer produces error messages in this scenario. (BZ#528758)

* Due to Security-Enhanced Linux (SELinux) settings, sending e-mails from the SquirrelMail web interface was blocked. This update adds a note to the SquirrelMail documentation that describes how to set the SELinux options to allow sending e-mails from the SquirrelMail web interface. (BZ#745380)

* Previously, the squirrelmail package did not comply with the RFC 2822 specification about line length limits. Consequently, attachments with lines longer than 998 characters could not be forwarded using SquirrelMail. This patch modifies the underlying source code and now SquirrelMail complies with the RFC 2822 specification as expected.
(BZ#745469)

* Prior to this update, the squirrelmail package required the php-common script instead of the mod_php script during installation or upgrade of the package, which led to a dependency error. As a result, attempting to install or upgrade the squirrelmail package failed on systems using the php53 packages. With this update, the dependencies of the squirrelmail package were changed and the installation or upgrade now works correctly in the described scenario. (BZ#789353)

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

Updated wireshark packages that fix several security issues, three 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.

Wireshark, previously known as Ethereal, is a network protocol analyzer. It is used to capture and browse the traffic running on a computer network.

A heap-based buffer overflow flaw was found in the way Wireshark handled Endace ERF (Extensible Record Format) capture files. If Wireshark opened a specially crafted ERF capture file, it could crash or, possibly, execute arbitrary code as the user running Wireshark.
(CVE-2011-4102)

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-2011-1958, CVE-2011-1959, CVE-2011-2175, CVE-2011-2698, CVE-2012-0041, CVE-2012-0042, CVE-2012-0066, CVE-2012-0067, CVE-2012-4285, CVE-2012-4289, CVE-2012-4290, CVE-2012-4291)

The CVE-2011-1958, CVE-2011-1959, CVE-2011-2175, and CVE-2011-4102 issues were discovered by Huzaifa Sidhpurwala of the Red Hat Security Response Team.

This update also fixes the following bugs :

* When Wireshark starts with the X11 protocol being tunneled through an SSH connection, it automatically prepares its capture filter to omit the SSH packets. If the SSH connection was to a link-local IPv6 address including an interface name (for example ssh -X [ipv6addr]%eth0), Wireshark parsed this address erroneously, constructed an incorrect capture filter and refused to capture packets. The 'Invalid capture filter' message was displayed. With this update, parsing of link-local IPv6 addresses is fixed and Wireshark correctly prepares a capture filter to omit SSH packets over a link-local IPv6 connection. (BZ#438473)

* Previously, Wireshark's column editing dialog malformed column names when they were selected. With this update, the dialog is fixed and no longer breaks column names. (BZ#493693)

* Previously, TShark, the console packet analyzer, did not properly analyze the exit code of Dumpcap, Wireshark's packet capturing back end. As a result, TShark returned exit code 0 when Dumpcap failed to parse its command-line arguments. In this update, TShark correctly propagates the Dumpcap exit code and returns a non-zero exit code when Dumpcap fails. (BZ#580510)

* Previously, the TShark '-s' (snapshot length) option worked only for a value greater than 68 bytes. If a lower value was specified, TShark captured just 68 bytes of incoming packets. With this update, the '-s' option is fixed and sizes lower than 68 bytes work as expected.
(BZ#580513)

This update also adds the following enhancement :

* In this update, support for the 'NetDump' protocol was added.
(BZ#484999)

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

Updated net-snmp packages that fix one security issue and multiple 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. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

These packages provide various libraries and tools for the Simple Network Management Protocol (SNMP).

An out-of-bounds buffer read flaw was found in the net-snmp agent. A remote attacker with read privileges to a Management Information Base (MIB) subtree handled by the 'extend' directive (in '/etc/snmp/snmpd.conf') could use this flaw to crash snmpd via a crafted SNMP GET request. (CVE-2012-2141)

Bug fixes :

* Devices that used certain file systems were not reported in the 'HOST-RESOURCES-MIB::hrStorageTable' table. As a result, the snmpd daemon did not recognize devices using tmpfs, ReiserFS, and Oracle Cluster File System (OCFS2) file systems. This update recognizes these devices and reports them in the 'HOST-RESOURCES-MIB::hrStorageTable' table. (BZ#754652, BZ#755958, BZ#822061)

* The snmptrapd (8) man page did not correctly describe how to load multiple configuration files using the '-c' option. This update describes correctly that multiple configuration files must be separated by a comma. (BZ#760001)

* Integers truncated from 64 to 32-bit were not correctly evaluated.
As a consequence, the snmpd daemon could enter an endless loop when encoding the truncated integers to network format. This update modifies the underlying code so that snmpd correctly checks truncated 64-bit integers. Now, snmpd avoids an endless loop. (BZ#783892)

* snmpd did not correctly check for interrupted system calls when enumerating existing IPv6 network prefixes during startup. As a consequence, snmpd could prematurely exit when receiving a signal during this enumeration. This update checks the network prefix enumeration code for interrupted system calls. Now, snmpd no longer terminates when a signal is received. (BZ#799699)

* snmpd used the wrong length of COUNTER64 values in the AgentX protocol. As a consequence, snmpd could not decode two consecutive COUNTER64 values in one AgentX packet. This update uses the correct COUNTER64 size and can process two or mode COUNTER64 values in AgentX communication. (BZ#803585)

* snmpd ignored the '-e' parameter of the 'trapsess' option in the snmpd configuration file. As a result, outgoing traps were incorrectly sent with the default EngineID of snmpd when configuring 'trapsess' with an explicit EngineID. This update modifies the underlying code to send outgoing traps using the EngineID as specified in the 'trapsess
-e' parameter in the configuration file. (BZ#805689)

* snmpd did not correctly encode negative Request-IDs in outgoing requests, for example during trap operations. As a consequence, a 32-bit value could be encoded in 5 bytes instead of 4, and the outgoing requests were refused by certain implementations of the SNMP protocol as invalid. With this update, a Request-ID can no longer become negative and is always encoded in 4 bytes. (BZ#818259)

* snmpd ignored the port number of the 'clientaddr' option when specifying the source address of outgoing SNMP requests. As a consequence, the system assigned a random address. This update allows to specify both the port number and the source IP address in the 'clientaddr' option. Now, administrators can increase security with firewall rules and Security-Enhanced Linux (SELinux) policies by configuring a specific source port of outgoing traps and other requests. (BZ#828691)

* snmpd did not correctly process responses to internal queries when initializing monitoring enabled by the 'monitor' option in the '/etc/snmp/snmpd.conf' configuration file. As a consequence, snmpd was not fully initialized and the error message 'failed to run mteTrigger query' appeared in the system log 30 seconds after the snmpd startup.
This update explicitly checks for responses to internal monitoring queries. (BZ#830042)

Users of net-snmp should upgrade to these updated packages, which contain backported patches to correct these issues. After installing the update, the snmpd and snmptrapd daemons will be restarted automatically.

Updated OpenIPMI packages that fix one security issue, multiple 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 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 OpenIPMI packages provide command line tools and utilities to access platform information using Intelligent Platform Management Interface (IPMI). System administrators can use OpenIPMI to manage systems and to perform system health monitoring.

It was discovered that the IPMI event daemon (ipmievd) created its process ID (PID) file with world-writable permissions. A local user could use this flaw to make the ipmievd init script kill an arbitrary process when the ipmievd daemon is stopped or restarted.
(CVE-2011-4339)

Note: This issue did not affect the default configuration of OpenIPMI as shipped with Red Hat Enterprise Linux 5.

This update also fixes the following bugs :

* Prior to this update, the ipmitool utility first checked the IPMI hardware for Dell IPMI extensions and listed only supported commands when printing command usage like the option 'ipmtool delloem help'. On a non-Dell platform, the usage text was incomplete and misleading.
This update lists all Dell OEM extensions in usage texts on all platforms, which allows users to check for command line arguments on non-Dell hardware. (BZ#658762)

* Prior to this update, the ipmitool utility tried to retrieve the Sensor Data Records (SDR) from the IPMI bus instead of the Baseboard Management Controller (BMC) bus when IPMI-enabled devices reported SDR under a different owner than the BMC. As a consequence, the timeout setting for the SDR read attempt could significantly decrease the performance and no sensor data was shown. This update modifies ipmitool to read these SDR records from the BMC and shows the correct sensor data on these platforms. (BZ#671059, BZ#749796)

* Prior to this update, the exit code of the 'ipmitool -o list' option was not set correctly. As a consequence, 'ipmitool -o list' always returned the value 1 instead of the expected value 0. This update modifies the underlying code to return the value 0 as expected.
(BZ#740780)

* Prior to this update, the 'ipmi' service init script did not specify the full path to the '/sbin/lsmod' and '/sbin/modprobe' system utilities. As a consequence, the init script failed when it was executed if PATH did not point to /sbin, for example, when running 'sudo /etc/init.d/ipmi'. This update modifies the init script so that it now contains the full path to lsmod and modrpobe. Now, it can be executed with sudo. (BZ#829705)

* Prior to this update, the ipmitool man page did not list the '-b', '-B', '-l' and '-T' options. In this update, these options are documented in the ipmitool man page. (BZ#846596)

This update also adds the following enhancement :

* Updates to the Dell-specific IPMI extension: A new vFlash command, which allows users to display information about extended SD cards; a new setled command, which allows users to display the backplane LED status; improved error descriptions; added support for new hardware;
and updated documentation of the ipmitool delloem commands in the ipmitool manual page. (BZ#797050)

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

Updated tcl packages that fix two security issues 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. 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.

Tcl (Tool Command Language) provides a powerful platform for creating integration applications that tie together diverse applications, protocols, devices, and frameworks. When paired with the Tk toolkit, Tcl provides a fast and powerful way to create cross-platform GUI applications.

Two denial of service flaws were found in the Tcl regular expression handling engine. If Tcl or an application using Tcl processed a specially crafted regular expression, it would lead to excessive CPU and memory consumption. (CVE-2007-4772, CVE-2007-6067)

This update also fixes the following bug :

* Due to a suboptimal implementation of threading in the current version of the Tcl language interpreter, an attempt to use threads in combination with fork in a Tcl script could cause the script to stop responding. At the moment, it is not possible to rewrite the source code or drop support for threading entirely. Consequent to this, this update provides a version of Tcl without threading support in addition to the standard version with this support. Users who need to use fork in their Tcl scripts and do not require threading can now switch to the version without threading support by using the alternatives command. (BZ#478961)

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

Updated mysql 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.

MySQL is a multi-user, multi-threaded SQL database server. It consists of the MySQL server daemon (mysqld) and many client programs and libraries.

It was found that the fix for the CVE-2009-4030 issue, a flaw in the way MySQL checked the paths used as arguments for the DATA DIRECTORY and INDEX DIRECTORY directives when the 'datadir' option was configured with a relative path, was incorrectly removed when the mysql packages in Red Hat Enterprise Linux 5 were updated to version 5.0.95 via RHSA-2012:0127. An authenticated attacker could use this flaw to bypass the restriction preventing the use of subdirectories of the MySQL data directory being used as DATA DIRECTORY and INDEX DIRECTORY paths. This update re-applies the fix for CVE-2009-4030.
(CVE-2012-4452)

Note: If the use of the DATA DIRECTORY and INDEX DIRECTORY directives were disabled as described in RHSA-2010:0109 (by adding 'symbolic-links=0' to the '[mysqld]' section of the 'my.cnf' configuration file), users were not vulnerable to this issue.

This issue was discovered by Karel Volny of the Red Hat Quality Engineering team.

This update also fixes the following bugs :

* Prior to this update, the log file path in the logrotate script did not behave as expected. As a consequence, the logrotate function failed to rotate the '/var/log/mysqld.log' file. This update modifies the logrotate script to allow rotating the mysqld.log file.
(BZ#647223)

* Prior to this update, the mysqld daemon could fail when using the EXPLAIN flag in prepared statement mode. This update modifies the underlying code to handle the EXPLAIN flag as expected. (BZ#654000)

* Prior to this update, the mysqld init script could wrongly report that mysql server startup failed when the server was actually started.
This update modifies the init script to report the status of the mysqld server as expected. (BZ#703476)

* Prior to this update, the '--enable-profiling' option was by default disabled. This update enables the profiling feature. (BZ#806365)

All MySQL users are advised to upgrade to these updated packages, which contain backported patches to resolve these issues. After installing this update, the MySQL server daemon (mysqld) will be restarted automatically.

An updated quota package that fixes one security issue and multiple 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 quota package provides system administration tools for monitoring and limiting user and group disk usage on file systems.

It was discovered that the rpc.rquotad service did not use tcp_wrappers correctly. Certain hosts access rules defined in '/etc/hosts.allow' and '/etc/hosts.deny' may not have been honored, possibly allowing remote attackers to bypass intended access restrictions. (CVE-2012-3417)

This issue was discovered by the Red Hat Security Response Team.

This update also fixes the following bugs :

* Prior to this update, values were not properly transported via the remote procedure call (RPC) and interpreted by the client when querying the quota usage or limits for network-mounted file systems if the quota values were 2^32 kilobytes or greater. As a consequence, the client reported mangled values. This update modifies the underlying code so that such values are correctly interpreted by the client.
(BZ#667360)

* Prior to this update, warnquota sent messages about exceeded quota limits from a valid domain name if the warnquota tool was enabled to send warning e-mails and the superuser did not change the default warnquota configuration. As a consequence, the recipient could reply to invalid addresses. This update modifies the default warnquota configuration to use the reserved example.com. domain. Now, warnings about exceeded quota limits are sent from the reserved domain that inform the superuser to change to the correct value. (BZ#680429)

* Previously, quota utilities could not recognize the file system as having quotas enabled and refused to operate on it due to incorrect updating of /etc/mtab. This update prefers /proc/mounts to get a list of file systems with enabled quotas. Now, quota utilities recognize file systems with enabled quotas as expected. (BZ#689822)

* Prior to this update, the setquota(8) tool on XFS file systems failed to set disk limits to values greater than 2^31 kilobytes. This update modifies the integer conversion in the setquota(8) tool to use a 64-bit variable big enough to store such values. (BZ#831520)

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

An updated sos package that fixes one security issue, several bugs, and adds various enhancements 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.

Sos is a set of tools that gather information about system hardware and configuration.

The sosreport utility incorrectly included Certificate-based Red Hat Network private entitlement keys in the resulting archive of debugging information. An attacker able to access the archive could use the keys to access Red Hat Network content available to the host. This issue did not affect users of Red Hat Network Classic. (CVE-2011-4083)

This updated sos package also includes numerous bug fixes and enhancements. Space precludes documenting all of these changes in this advisory. Users are directed to the Red Hat Enterprise Linux 5.8 Technical Notes, linked to in the References, for information on the most significant of these changes.

All sos users are advised to upgrade to this updated package, which resolves these issues and adds these enhancements.

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

The Red Hat Security Response Team has rated this update as having critical 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 content.
Malicious content could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2013-0744, CVE-2013-0746, CVE-2013-0750, CVE-2013-0753, CVE-2013-0754, CVE-2013-0762, CVE-2013-0766, CVE-2013-0767, CVE-2013-0769)

A flaw was found in the way Chrome Object Wrappers were implemented.
Malicious content could be used to cause Thunderbird to execute arbitrary code via plug-ins installed in Thunderbird. (CVE-2013-0758)

A flaw in the way Thunderbird displayed URL values could allow malicious content or a user to perform a phishing attack.
(CVE-2013-0759)

An information disclosure flaw was found in the way certain JavaScript functions were implemented in Thunderbird. An attacker could use this flaw to bypass Address Space Layout Randomization (ASLR) and other security restrictions. (CVE-2013-0748)

Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Atte Kettunen, Boris Zbarsky, pa_kt, regenrecht, Abhishek Arya, Christoph Diehl, Christian Holler, Mats Palmgren, Chiaki Ishikawa, Mariusz Mlynski, Masato Kinugawa, and Jesse Ruderman as the original reporters of these issues.

Note: All issues except CVE-2013-0744, CVE-2013-0753, and CVE-2013-0754 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.

All Thunderbird users should upgrade to this updated package, which contains Thunderbird version 10.0.12 ESR, which corrects these issues.
After installing the update, Thunderbird must be restarted for the changes to take effect.
