               Fedora Legacy Update Advisory

Synopsis:          Updated gdk-pixbuf packages fix a security issue
Advisory ID:       FLSA:154272
Issue date:        2005-07-15
Product:           Red Hat Linux, Fedora Core
Keywords:          Bugfix
CVE Names:         CAN-2005-0891
- ---------------------------------------------------------------------


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

Updated gdk-pixbuf packages that fix a double free vulnerability are now
available.

The gdk-pixbuf package contains an image loading library used with the
GNOME GUI desktop environment.

2. Relevant releases/architectures:

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

3. Problem description:

A bug was found in the way gdk-pixbuf processes BMP images. It is
possible that a specially crafted BMP image could cause a denial of
service attack on applications linked against gdk-pixbuf. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the
name CAN-2005-0891 to this issue.

Users of gdk-pixbuf are advised to upgrade to these packages, which
contain a backported patch and are not vulnerable to this issue.

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.
