"From Red Hat Security Advisory 2008:0064 :

An updated X.Org libXfont package that fixes a security issue is 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.

The libXfont package contains the X.Org X11 libXfont runtime library.

A heap based buffer overflow flaw was found in the way the X.Org
server handled malformed font files. A malicious local user could
exploit this issue to potentially execute arbitrary code with the
privileges of the X.Org server. (CVE-2008-0006)

Users of X.Org libXfont should upgrade to these updated packages,
which contain a backported patch to resolve this issue."
