Critical updates to giflib libraries have been implemented to mitigate security risks in Red Hat Enterprise Linux. Users are urged to act swiftly.
Updated giflib packages that fix several security issues are now available for Red Hat Enterprise Linux 5

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

Summary

The giflib packages contain a shared library of functions for loading and saving GIF image files. This library is API and ABI compatible with libungif, the library that supported uncompressed GIF image files while the Unisys LZW patent was in effect.
Several flaws were discovered in the way giflib decodes GIF images. An attacker could create a carefully crafted GIF image that could cause an application using giflib to crash or, possibly, execute arbitrary code when opened by a victim. (CVE-2005-2974, CVE-2005-3350)
All users of giflib are advised to upgrade to these updated packages, which contain backported patches to resolve these issues. All running applications using giflib must be restarted for the update to take effect.
