"Updated kernel packages that fix one security issue, several bugs, and
add various enhancements are now available as part of the ongoing
support and maintenance of Red Hat Enterprise Linux version 5. This is
the tenth regular update.

The Red Hat Security Response Team has rated this update as having
moderate 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 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."
