Description

Updated kernel packages that fix two security issues and several bugs 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.

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

This update fixes the following security issues:

An integer overflow flaw was found in the i915_gem_execbuffer2() function

in the Intel i915 driver in the Linux kernel. A local, unprivileged user
could use this flaw to cause a denial of service. This issue only affected
32-bit systems. (CVE-2012-2383, Moderate)

A missing initialization flaw was found in the sco_sock_getsockopt_old()

function in the Linux kernel\‘s Bluetooth implementation. A local,
unprivileged user could use this flaw to cause an information leak.
(CVE-2011-1078, Low)

Red Hat would like to thank Vasiliy Kulikov of Openwall for reporting the
CVE-2011-1078 issue.

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.
