The remote Red Hat host is missing one or more security updates.
Updated libXfont packages that fix one security issue are now
available for Red Hat Enterprise Linux 5 and 6.
The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System
(CVSS) base score, which gives a detailed severity rating, is
available from the CVE link in the References section.
The libXfont packages provide the X.Org libXfont runtime library.
X.Org is an open source implementation of the X Window System.
A stack-based buffer overflow flaw was found in the way the libXfont
library parsed Glyph Bitmap Distribution Format (BDF) fonts. A
malicious, local user could exploit this issue to potentially execute
arbitrary code with the privileges of the X.Org server.
Users of libXfont should upgrade to these updated packages, which
contain a backported patch to resolve this issue. All running X.Org
server instances must be restarted for the update to take effect.
