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.
