Synopsis: Important: xorg-x11 security update
Issue Date: 2011-08-11
CVE Numbers: CVE-2011-2895
 CVE-2011-2895

X.Org is an open source implementation of the X Window System. It
provides the basic low-level functionality that full-fledged graphical
user interfaces are designed upon. These xorg-x11 packages also provide
the X.Org libXfont runtime library.

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 xorg-x11 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.
