Description

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.
