RedHat: Important: giflib security update
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.
Summary
Solution
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
