Details

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.
