The remote Red Hat host is missing one or more security updates.
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
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.
