Please Install the Updated Packages.

The Common UNIX Printing System (CUPS) provides a portable printing layer for UNIX operating systems. A use-after-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 or, potentially, execute arbitrary code with the privileges of the CUPS server. (CVE-2010-2941) A possible privilege escalation flaw was found in CUPS. An unprivileged process running as the &quot lp&quot user (such as a compromised external filter program spawned by the CUPS server) could trick the CUPS server into overwriting arbitrary files as the root user. (CVE-2010-2431) Red Hat would like to thank Emmanuel Bouillon of NATO C3 Agency for reporting the CVE-2010-2941 issue. Users of cups are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing this update, the cupsd daemon will be restarted automatically.
