kernel security update

CentOS Errata and Security Advisory CESA-2013:1348

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 a deadlock could occur in the Out of Memory (OOM)
  killer. A process could trigger this deadlock by consuming a large amount
  of memory, and then causing request_module() to be called. A local,
  unprivileged user could use this flaw to cause a denial of service
  (excessive memory consumption). (CVE-2012-4398, Moderate)

Red Hat would like to thank Tetsuo Handa for reporting this issue.

This update also fixes numerous bugs and adds various enhancements. Refer
to the Red Hat Enterprise Linux 5.10 Release Notes for information on the
most significant of these changes, and the Technical Notes for further
information, both linked to in the References.

All Red Hat Enterprise Linux 5 users are advised to install these updated
packages, which correct this issue, and fix the bugs and add the
enhancements noted in the Red Hat Enterprise Linux 5.10 Release Notes and
Technical Notes. The system must be rebooted for this update to take
effect.
