Description

Updated gd packages that fix several buffer overflow flaws are now available.

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

The gd package contains a graphics library used for the dynamic creation of images such as PNG and JPEG.

Several buffer overflow flaws were found in the way gd allocates memory. An attacker could create a carefully crafted image that could execute arbitrary code if opened by a victim using a program linked against the gd library. The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the name CVE-2004-0941 to these issues.

Users of gd should upgrade to these updated packages, which contain a backported patch and is not vulnerable to these issues.
