RedHat Security Advisory RHSA-2009:1082

The remote host is missing updates announced in advisory RHSA-2009:1082. The Common UNIX® Printing System (CUPS) provides a portable printing layer for UNIX operating systems. The Internet Printing Protocol (IPP) allows users to print and manage printing-related tasks over a network. A NULL pointer dereference flaw was found in the CUPS IPP routine, used for processing incoming IPP requests for the CUPS scheduler. An attacker could use this flaw to send specially-crafted IPP requests that would crash the cupsd daemon. (CVE-2009-0949) Red Hat would like to thank Anibal Sacco from Core Security Technologies 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.
