Posted on: 03/17/2006 10:21 AM

Fedora Legacy Update Advisory

Synopsis: Updated libungif packages fix security issues
Advisory ID: FLSA:174479
Issue date: 2006-03-16
Product: Red Hat Linux, Fedora Core
Keywords: Bugfix
CVE Names: CVE-2005-2974 CVE-2005-3350
---------------------------------------------------------------------

---------------------------------------------------------------------
1. Topic:

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

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

2. Relevant releases/architectures:

Red Hat Linux 7.3 - i386
Red Hat Linux 9 - i386
Fedora Core 1 - i386
Fedora Core 2 - i386

3. Problem description:

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.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which
are not installed but included in the list will not be updated. Note
that you can also use wildcards (*.rpm) if your current directory *only*
contains the desired RPMs.

Please note that this update is also available via yum and apt. Many
people find this an easier way to apply updates. To use yum issue:

yum update

or to use apt:

apt-get update; apt-get upgrade

This will start an interactive process that will result in the
appropriate RPMs being upgraded on your system. This assumes that you
have yum or apt-get configured for obtaining Fedora Legacy content.
Please visit http://www.fedoralegacy.org/docs for directions on how to
configure yum and apt-get.
