CVE-2012-2136 linux

Updated kernel packages that fix one security issue and various bugs are
now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having
important 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
operating system.

This update fixes the following security issue:

* It was found that the data_len parameter of the sock_alloc_send_pskb()
function in the Linux kernel's networking implementation was not validated
before use. A local user with access to a TUN/TAP virtual interface could
use this flaw to crash the system or, potentially, escalate their
privileges. Note that unprivileged users cannot access TUN/TAP devices
until the root user grants them access. (CVE-2012-2136, Important)

This update also fixes various 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 this issue, and fix the bugs noted in the Technical
Notes. The system must be rebooted for this update to take effect.
