Red Hat Security Advisory
Synopsis: Low: kernel security and bug fix update
Advisory ID: RHSA-2013:0594-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2013-0594.html
Issue date: 2013-03-05
CVE Names: CVE-2012-3400
=====================================================================
1. Summary:
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.
2. Relevant releases/architectures:
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, noarch, ppc, s390x, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, noarch, x86_64
3. Description:
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.
4. Solution:
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/knowledge/articles/11258
To install kernel packages manually, use "rpm -ivh [package]". Do not
use "rpm -Uvh" as that will remove the running kernel binaries from
your system. You may use "rpm -e" to remove old kernels after
determining that the new kernel functions properly on your system.
5. Bugs fixed (http://bugzilla.redhat.com/):
843139 - CVE-2012-3400 kernel: udf: buffer overflow when parsing sparing table
