RHSA-2009:0428 - Moderate: cups security update

Synopsis

Moderate: cups security update

Type/Severity

Security Advisory Moderate

Topic

Updated cups packages that fix one security issue are now available for Red Hat Enterprise Linux 3.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

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.
