Important: giflib security update

Advisory:	RHSA-2009:0444-1
Type:	Security Advisory
Severity:	Important
Issued on:	2009-04-22
Last updated on:	2009-04-22
Affected Products:	RHEL Desktop Workstation (v. 5 client) Red Hat Enterprise Linux (v. 5 server) Red Hat Enterprise Linux Desktop (v. 5 client) Red Hat Enterprise Linux EUS (v. 5.3.z server) Red Hat Enterprise Linux Long Life (v. 5.3 server)
CVEs (cve.mitre.org):	CVE-2005-2974 CVE-2005-3350

Details

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.

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
