=====================================================================

1. Summary:

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.

3. Description:

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

issue to potentially execute arbitrary code with the privileges of the
X.Org server. (CVE-2008-0006)

contain a backported patch to resolve this issue.
