| Description: | The Common UNIX® Printing System (CUPS) provides a portable printing layer for UNIX operating systems.
An integer overflow flaw, leading to a heap-based buffer overflow, was discovered in the Tagged Image File Format (TIFF) decoding routines used by the CUPS image-converting filters, "imagetops" and "imagetoraster". An attacker could create a malicious TIFF file that could, potentially, execute arbitrary code as the "lp" user if the file was printed. (CVE-2009-0163)
Red Hat would like to thank Aaron Sigel of the Apple Product Security team for responsibly reporting this flaw.
Users of cups are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. After installing the update, the cupsd daemon will be restarted automatically.
