RHSA-2009:0444 - Important: giflib security update
Synopsis
Important: giflib security update
Type/Severity
Security Advisory Important
Topic
Updated giflib packages that fix several security issues are now available for Red Hat Enterprise Linux 5.
This update has been rated as having important security impact by the Red Hat Security Response Team.
Description
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.
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 This content is not included.http://kbase.redhat.com/faq/docs/DOC-11259
