"Updated X.org libXfont packages that fix a security issue are now
available for Red Hat Enterprise Linux 5.

This update has been rated as having important security impact by the
Red Hat Security Response Team.

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.

iDefense reported two integer overflows in the way X.org handled
various font files. A malicious local user could exploit these issues
to potentially execute arbitrary code with the privileges of the X.org
server. (CVE-2007-1351, CVE-2007-1352)

Users of X.org libXfont should upgrade to these updated packages,
which contain a backported patch and are not vulnerable to this issue."
