RedHat: RHSA-2009-1082:01 Important: cups security update
Summary
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.
Summary
Solution
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
This update is available via Red Hat Network. Details on how to use
the Red Hat Network to apply this update are available at
