"Updated XFree86 packages that fix a security issue are now available
for Red Hat Enterprise Linux 2.1 and 3.

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

XFree86 is an implementation of the X Window System, which provides
the core functionality for the Linux graphical desktop.

iDefense reported two integer overflow flaws in the way the XFree86
server processed CID font files. A malicious authorized client could
exploit this issue to cause a denial of service (crash) or potentially
execute arbitrary code with root privileges on the XFree86 server.
(CVE-2006-3739, CVE-2006-3740)

Users of XFree86 should upgrade to these updated packages, which
contain a backported patch and is not vulnerable to this issue."
