Test ID:1.3.6.1.4.1.25623.1.0.70067
Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2011:1154
Summary:NOSUMMARY
Description:Description:
The remote host is missing updates announced in
advisory RHSA-2011:1154.

The libXfont packages provide the X.Org libXfont runtime library. X.Org is
an open source implementation of the X Window System.

A buffer overflow flaw was found in the way the libXfont library, used by
the X.Org server, handled malformed font files compressed using UNIX
compress. A malicious, local user could exploit this issue to potentially
execute arbitrary code with the privileges of the X.Org server.
(CVE-2011-2895)

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.

Solution:
Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
