Updated xorg-x11-server packages that fix one security issue are now
available for Red Hat Enterprise Linux 5 and 6.

X.Org is an open source implementation of the X Window System. It
provides the basic low-level functionality that full-fledged graphical
user interfaces are designed upon.
A use-after-free flaw was found in the way the X.Org server handled
ImageText requests. A malicious, authorized client could use this flaw
to crash the X.Org server or, potentially, execute arbitrary code with
root privileges. (CVE-2013-4396)
Red Hat would like to thank the X.Org security team for reporting this
issue. Upstream acknowledges Pedro Ribeiro as the original reporter.
All xorg-x11-server users are advised to upgrade to these updated
packages, which contain a backported patch to correct this issue.
