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.
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:
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.
