Scientific Linux Security Update : libXfont on SL5.x, SL6.x i386/x86_64

high Nessus Plugin ID 61108

Language:

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

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

Update the affected libXfont and / or libXfont-devel packages.
