1. Summary:

An updated foomatic package that fixes one security issue is now available
for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate
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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64
Red Hat Enterprise Linux HPC Node (v. 6) - x86_64
Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64
Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64

3. Description:

Foomatic is a comprehensive, spooler-independent database of printers,
printer drivers, and driver descriptions. The package also includes
spooler-independent command line interfaces to manipulate queues and to
print files and manipulate print jobs. foomatic-rip is a print filter
written in C.

An input sanitization flaw was found in the foomatic-rip print filter. An
attacker could submit a print job with the username, title, or job options
set to appear as a command line option that caused the filter to use a
specified PostScript printer description (PPD) file, rather than the
administrator-set one. This could lead to arbitrary code execution with the
privileges of the "lp" user. (CVE-2011-2964)

All foomatic users should upgrade to this updated package, which contains
a backported patch to resolve this issue.

4. Solution:

Before applying this update, make sure all previously-released errata
