"From Red Hat Security Advisory 2010:0866 :

Updated cups packages that fix one security issue are now available
for Red Hat Enterprise Linux 6.

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

The Common UNIX Printing System (CUPS) provides a portable printing
layer for UNIX operating systems.

An invalid free flaw was found in the way the CUPS server parsed
Internet Printing Protocol (IPP) packets. A malicious user able to
send IPP requests to the CUPS server could use this flaw to crash the
CUPS server. (CVE-2010-2941)

Red Hat would like to thank Emmanuel Bouillon of NATO C3 Agency for
reporting this issue.

Users of cups are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue. After installing
this update, the cupsd daemon will be restarted automatically.");
