"Updated kernel packages that fix two security issues and one bug are
now available for Red Hat Enterprise Linux 5.9 Extended Update
Support.

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.

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

* A buffer overflow flaw was found in the way the qeth_snmp_command()
function in the Linux kernel's QETH network device driver
implementation handled SNMP IOCTL requests with an out-of-bounds
length. A local, unprivileged user could use this flaw to crash the
system or, potentially, escalate their privileges on the system.
(CVE-2013-6381, Important)

* A flaw was found in the way the Linux kernel's Adaptec RAID
controller (aacraid) checked permissions of compat IOCTLs. A local
attacker could use this flaw to bypass intended security restrictions.
(CVE-2013-6383, Moderate)

This update also fixes the following bug :

* Running a process in the background on a GFS2 file system could
sometimes trigger a glock recursion error that resulted in a kernel
panic. This happened when a readpage operation attempted to take a
glock that had already been held by another function. To prevent this
error, GFS2 now verifies whether the glock is already held when
performing the readpage operation. (BZ#1077789)

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."
