Description

Updated libungif packages that fix two security issues are now available.

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

The libungif package contains a shared library of functions for loading and saving GIF format image files.

Several bugs in the way libungif decodes GIF images were discovered. An attacker could create a carefully crafted GIF image file in such a way that it could cause an application linked with libungif to crash or execute arbitrary code when the file is opened by a victim. The Common Vulnerabilities and Exposures project has assigned the names CVE-2005-2974 and CVE-2005-3350 to these issues.

All users of libungif are advised to upgrade to these updated packages, which contain backported patches that resolve these issues.
