Red Hat would like to thank Hannes Frederic Sowa for reporting CVE-2013-4162.

This update also fixes the following bugs :

* A bug in the be2net driver prevented communication between NICs using be2net. This update applies a patch addressing this problem along with several other upstream patches that fix various other problems. Traffic between NICs using the be2net driver now proceeds as expected. (BZ#983864)

* A recent patch fixing a problem that prevented communication between NICs using the be2net driver caused the firmware of NICs to become unresponsive, and thus triggered a kernel panic. The problem was caused by unnecessary usage of a hardware workaround that allows skipping VLAN tag insertion. A patch has been applied and the workaround is now used only when the multi-channel configuration is enabled on the NIC. Note that the bug only affected the NICs with firmware version 4.2.xxxx. (BZ#999819)

* A bug in the autofs4 mount expiration code could cause the autofs4 module to falsely report a busy tree of NFS mounts as 'not in use'.
Consequently, automount attempted to unmount the tree and failed with a 'failed to umount offset' error, leaving the mount tree to appear as empty directories. A patch has been applied to remove an incorrectly used autofs dentry mount check and the aforementioned problem no longer occurs. (BZ#1001488)

* A race condition in the be_open function in the be2net driver could trigger the BUG_ON() macro, which resulted in a kernel panic. A patch addressing this problem has been applied and the race condition is now avoided by enabling polling before enabling interrupts globally. The kernel no longer panics in this situation. (BZ#1005239)

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.

This update also fixes the following bugs :

* Prior to this update, the libvirtd daemon leaked memory in the virCgroupMoveTask() function. A fix has been provided which prevents libvirtd from incorrect management of memory allocations. (BZ#984556)

* Previously, the libvirtd daemon was accessing one byte before the array in the virCgroupGetValueStr() function. This bug has been fixed and libvirtd now stays within the array bounds. (BZ#984561)

* When migrating, libvirtd leaked the migration URI (Uniform Resource Identifier) on destination. A patch has been provided to fix this bug and the migration URI is now freed correctly. (BZ#984578)

* Updating a network interface using virDomainUpdateDeviceFlags API failed when a boot order was set for that interface. The update failed even if the boot order was set in the provided device XML. The virDomainUpdateDeviceFlags API has been fixed to correctly parse the boot order specification from the provided device XML and updating network interfaces with boot orders now works as expected.
(BZ#1003934)

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.

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-2013-1620)

An out-of-bounds memory read flaw was found in the way NSS decoded certain certificates. If an application using NSS decoded a malformed certificate, it could cause the application to crash. (CVE-2013-0791)

Red Hat would like to thank the Mozilla project for reporting CVE-2013-0791. Upstream acknowledges Ambroz Bizjak as the original reporter of CVE-2013-0791.

This update also fixes the following bugs :

* A defect in the FreeBL library implementation of the Diffie-Hellman (DH) protocol previously caused Openswan to drop connections.
(BZ#958023)

* A memory leak in the nssutil_ReadSecmodDB() function has been fixed.
(BZ#986969)

In addition, the nss package has been upgraded to upstream version 3.14.3, and the nspr package has been upgraded to upstream version 4.9.5. These updates provide a number of bug fixes and enhancements over the previous versions. (BZ#949845, BZ#924741)

Note that while upstream NSS version 3.14 prevents the use of certificates that have an MD5 signature, this erratum includes a patch that allows such certificates by default. To prevent the use of certificates that have an MD5 signature, set the 'NSS_HASH_ALG_SUPPORT' environment variable to '-MD5'.

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

An updated sos package that fixes one security issue 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 sos package contains a set of tools that gather information from system hardware, logs and configuration files. The information can then be used for diagnostic purposes and debugging.

The sosreport utility collected the Kickstart configuration file ('/root/anaconda-ks.cfg'), but did not remove the root user's password from it before adding the file to the resulting archive of debugging information. An attacker able to access the archive could possibly use this flaw to obtain the root user's password. '/root/anaconda-ks.cfg' usually only contains a hash of the password, not the plain text password. (CVE-2012-2664)

Note: This issue affected all installations, not only systems installed via Kickstart. A '/root/anaconda-ks.cfg' file is created by all installation types.

The utility also collects yum repository information from '/etc/yum.repos.d' which in uncommon configurations may contain passwords. Any http_proxy password specified in these files will now be automatically removed. Passwords embedded within URLs in these files should be manually removed or the files excluded from the archive.

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

The 389 Directory Server is an LDAPv3 compliant server. The base packages include the Lightweight Directory Access Protocol (LDAP) server and command-line utilities for server administration.

It was discovered that the 389 Directory Server did not honor defined attribute access controls when evaluating search filter expressions. A remote attacker (with permission to query the Directory Server) could use this flaw to determine the values of restricted attributes via a series of search queries with filter conditions that used restricted attributes. (CVE-2013-2219)

This issue was discovered by Ludwig Krispenz of Red Hat.

This update also fixes the following bugs :

* Previously, the disk monitoring feature did not function properly.
If logging functionality was set to critical and logging was disabled, rotated logs would be deleted. If the attribute 'nsslapd-errorlog-level' was explicitly set to any value, even zero, the disk monitoring feature would not stop the Directory Server when it was supposed to. This update corrects the disk monitoring feature settings, and it no longer malfunctions in the described scenarios.
(BZ#972930)

* Previously, setting the 'nsslapd-disk-monitoring-threshold' attribute via ldapmodify to a large value worked as expected; however, a bug in ldapsearch caused such values for the option to be displayed as negative values. This update corrects the bug in ldapsearch and correct values are now displayed. (BZ#984970)

* If logging functionality was not set to critical, then the mount point for the logs directory was incorrectly skipped during the disk space check. (BZ#987850)

All 389-ds-base users are advised to upgrade to these updated packages, which contain backported patches to correct these issues.
After installing this update, the 389 server service will be restarted automatically.

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

This update fixes the following security issues :

* Information leaks in the Linux kernel could allow a local, unprivileged user to leak kernel memory to user-space. (CVE-2012-6544, CVE-2012-6545, CVE-2013-3222, CVE-2013-3224, CVE-2013-3231, CVE-2013-3235, Low)

* An information leak was found in the Linux kernel's POSIX signals implementation. A local, unprivileged user could use this flaw to bypass the Address Space Layout Randomization (ASLR) security feature.
(CVE-2013-0914, Low)

* A heap-based buffer overflow in the way the tg3 Ethernet driver parsed the vital product data (VPD) of devices could allow an attacker with physical access to a system to cause a denial of service or, potentially, escalate their privileges. (CVE-2013-1929, Low)

This update also fixes the following bugs :

* Previously on system boot, devices with associated Reserved Memory Region Reporting (RMRR) information had lost their RMRR information after they were removed from the static identity (SI) domain.
Consequently, a system unexpectedly terminated in an endless loop due to unexpected NMIs triggered by DMA errors. This problem was observed on HP ProLiant Generation 7 (G7) and 8 (Gen8) systems. This update prevents non-USB devices that have RMRR information associated with them from being placed into the SI domain during system boot. HP ProLiant G7 and Gen8 systems that contain devices with the RMRR information now boot as expected. (BZ#957606)

* Previously, the kernel's futex wait code used timeouts that had granularity in milliseconds. Also, when passing these timeouts to system calls, the kernel converted the timeouts to 'jiffies'.
Consequently, programs could time out inaccurately which could lead to significant latency problems in certain environments. This update modifies the futex wait code to use a high-resolution timer (hrtimer) so the timeout granularity is now in microseconds. Timeouts are no longer converted to 'jiffies' when passed to system calls. Timeouts passed to programs are now accurate and the programs time out as expected. (BZ#958021)

* A recent change modified the size of the task_struct structure in the floating point unit (fpu) counter. However, on Intel Itanium systems, this change caused the kernel Application Binary Interface (kABI) to stop working properly when a previously compiled module was loaded, resulting in a kernel panic. With this update the change causing this bug has been reverted so the bug can no longer occur.
(BZ#966878)

* The cxgb4 driver previously did not clear data structures used for firmware requests. Consequently, when initializing some Chelsio's Terminator 4 (T4) adapters, a probe request could fail because the request was incompatible with the adapter's firmware. This update modifies the cxgb4 driver to properly initialize firmware request structures before sending a request to the firmware and the problem no longer occurs. (BZ#971872)

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.

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 discovered that the PHP XSL extension did not restrict the file writing capability of libxslt. A remote attacker could use this flaw to create or overwrite an arbitrary file that is writable by the user running PHP, if a PHP script processed untrusted eXtensible Style Sheet Language Transformations (XSLT) content. (CVE-2012-0057)

Note: This update disables file writing by default. A new PHP configuration directive, 'xsl.security_prefs', can be used to enable file writing in XSLT.

A flaw was found in the way PHP validated file names in file upload requests. A remote attacker could possibly use this flaw to bypass the sanitization of the uploaded file names, and cause a PHP script to store the uploaded file in an unexpected directory, by using a directory traversal attack. (CVE-2012-1172)

Multiple integer overflow flaws, leading to heap-based buffer overflows, were found in the way the PHP phar extension processed certain fields of tar archive files. A remote attacker could provide a specially crafted tar archive file that, when processed by a PHP application using the phar extension, could cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running PHP. (CVE-2012-2386)

A format string flaw was found in the way the PHP phar extension processed certain PHAR files. A remote attacker could provide a specially crafted PHAR file, which once processed in a PHP application using the phar extension, could lead to information disclosure and possibly arbitrary code execution via a crafted phar:// URI.
(CVE-2010-2950)

A flaw was found in the DES algorithm implementation in the crypt() password hashing function in PHP. If the password string to be hashed contained certain characters, the remainder of the string was ignored when calculating the hash, significantly reducing the password strength. (CVE-2012-2143)

Note: With this update, passwords are no longer truncated when performing DES hashing. Therefore, new hashes of the affected passwords will not match stored hashes generated using vulnerable PHP versions, and will need to be updated.

It was discovered that the fix for CVE-2012-1823, released via RHSA-2012:0547, did not properly filter all php-cgi command line arguments. A specially crafted request to a PHP script could cause the PHP interpreter to execute the script in a loop, or output usage information that triggers an Internal Server Error. (CVE-2012-2336)

A memory leak flaw was found in the PHP strtotime() function call. A remote attacker could possibly use this flaw to cause excessive memory consumption by triggering many strtotime() function calls.
(CVE-2012-0789)

It was found that PHP did not check the zend_strndup() function's return value in certain cases. A remote attacker could possibly use this flaw to crash a PHP application. (CVE-2011-4153)

Upstream acknowledges Rubin Xu and Joseph Bonneau as the original reporters of CVE-2012-2143.

All php53 users should upgrade to these updated packages, which contain backported patches to resolve these issues. After installing the updated packages, the httpd daemon must be restarted for the update to take effect.

Updated samba3x and samba packages that fix one security issue are now available for Red Hat Enterprise Linux 5 and 6 respectively.

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.

A flaw was found in the way Samba handled certain Local Security Authority (LSA) Remote Procedure Calls (RPC). An authenticated user could use this flaw to issue an RPC call that would modify the privileges database on the Samba server, allowing them to steal the ownership of files and directories that are being shared by the Samba server, and create, delete, and modify user accounts, as well as other Samba server administration tasks. (CVE-2012-2111)

Red Hat would like to thank the Samba project for reporting this issue. Upstream acknowledges Ivano Cristofolini as the original reporter.

Users of Samba are advised to upgrade to these updated packages, which contain a backported patch to resolve this issue. After installing this update, the smb service will be restarted automatically.

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

It was found that the hashing routine used by PHP arrays was susceptible to predictable hash collisions. If an HTTP POST request to a PHP application contained many parameters whose names map to the same hash value, a large amount of CPU time would be consumed. This flaw has been mitigated by adding a new configuration directive, max_input_vars, that limits the maximum number of parameters processed per request. By default, max_input_vars is set to 1000.
(CVE-2011-4885)

An integer overflow flaw was found in the PHP exif extension. On 32-bit systems, a specially crafted image file could cause the PHP interpreter to crash or disclose portions of its memory when a PHP script tries to extract Exchangeable image file format (Exif) metadata from the image file. (CVE-2011-4566)

An insufficient input validation flaw, leading to a buffer over-read, was found in the PHP exif extension. A specially crafted image file could cause the PHP interpreter to crash when a PHP script tries to extract Exchangeable image file format (Exif) metadata from the image file. (CVE-2011-0708)

An integer overflow flaw was found in the PHP calendar extension. A remote attacker able to make a PHP script call SdnToJulian() with a large value could cause the PHP interpreter to crash. (CVE-2011-1466)

An off-by-one flaw was found in PHP. If an attacker uploaded a file with a specially crafted file name it could cause a PHP script to attempt to write a file to the root (/) directory. By default, PHP runs as the 'apache' user, preventing it from writing to the root directory. (CVE-2011-2202)

Red Hat would like to thank oCERT for reporting CVE-2011-4885. oCERT acknowledges Julian Walde and Alexander Klink as the original reporters of CVE-2011-4885.

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

This update fixes the following security issues :

* Using PCI passthrough without interrupt remapping support allowed Xen hypervisor guests to generate MSI interrupts and thus potentially inject traps. A privileged guest user could use this flaw to crash the host or possibly escalate their privileges on the host. The fix for this issue can prevent PCI passthrough working and guests starting.
Refer to Red Hat Bugzilla bug 715555 for details. (CVE-2011-1898, Important)

* A flaw was found in the way CIFS (Common Internet File System) shares with DFS referrals at their root were handled. An attacker on the local network who is able to deploy a malicious CIFS server could create a CIFS network share that, when mounted, would cause the client system to crash. (CVE-2011-3363, Moderate)

* A NULL pointer dereference flaw was found in the way the Linux kernel's key management facility handled user-defined key types. A local, unprivileged user could use the keyctl utility to cause a denial of service. (CVE-2011-4110, Moderate)

* A flaw in the way memory containing security-related data was handled in tpm_read() could allow a local, unprivileged user to read the results of a previously run TPM command. (CVE-2011-1162, Low)

* A NULL pointer dereference flaw was found in the Linux kernel's HFS file system implementation. A local attacker could use this flaw to cause a denial of service by mounting a disk that contains a specially crafted HFS file system with a corrupted MDB extent record.
(CVE-2011-2203, Low)

* The I/O statistics from the taskstats subsystem could be read without any restrictions. A local, unprivileged user could use this flaw to gather confidential information, such as the length of a password used in a process. (CVE-2011-2494, Low)

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

A flaw was found in the way large amounts of memory were allocated on 64-bit systems when using the BigDecimal class. A context-dependent attacker could use this flaw to cause memory corruption, causing a Ruby application that uses the BigDecimal class to crash or, possibly, execute arbitrary code. This issue did not affect 32-bit systems.
(CVE-2011-0188)

A race condition flaw was found in the remove system entries method in the FileUtils module. If a local user ran a Ruby script that uses this method, a local attacker could use this flaw to delete arbitrary files and directories accessible to that user via a symbolic link attack.
(CVE-2011-1004)

It was found that WEBrick (the Ruby HTTP server toolkit) did not filter terminal escape sequences from its log files. A remote attacker could use specially crafted HTTP requests to inject terminal escape sequences into the WEBrick log files. If a victim viewed the log files with a terminal emulator, it could result in control characters being executed with the privileges of that user. (CVE-2009-4492)

A cross-site scripting (XSS) flaw was found in the way WEBrick displayed error pages. A remote attacker could use this flaw to perform a cross-site scripting attack against victims by tricking them into visiting a specially crafted URL. (CVE-2010-0541)

A flaw was found 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-2011-1005)

Red Hat would like to thank Drew Yao of Apple Product Security for reporting the CVE-2011-0188 and CVE-2010-0541 issues.
