Updated X.org packages that fix a security issue are now available.
X.org is an open source implementation of the X Window System. It provides the basic low-level functionality that full-fledged graphical user interfaces (GUIs) such as GNOME and KDE are designed upon.
2. Relevant releases/architectures:
Fedora Core 2 - i386
3. Problem description:
Several integer overflow bugs were found in the way X.org parses pixmap images. It is possible for a user to gain elevated privileges by loading a specially crafted pixmap image. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2005-2495 to this issue.
Users of X.org should upgrade to these updated 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.
