Fedora Core 4 : xorg-x11-6.8.2-37.FC4.48.1 (2005-894)

Medium Nessus Plugin ID 19740


The remote Fedora Core host is missing a security update.


Updated xorg-x11 packages that fix several integer overflows, various bugs, are now available for Fedora Core 4.

X.Org X11 is an implementation of the X Window System, which provides the core functionality for the Linux graphical desktop.

Several integer overflow bugs were found in the way X.Org X11 code 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.

Additionally, this update contains :

- Support for some newer models of Intel i945 video chipsets.

- A fix for a regression caused in the last Xorg update for Fedora Core 4, which resulted in some Matrox hardware to fail to initialize properly, which was introduced in the PCI config space access bugfix from the previous xorg-x11 update. The PCI config code has been updated now to handle BIOS related quirks of this nature, so this fix may also benefit users of some other brands of video hardware as well.

- A fix for a memory leak in the X server's shadow framebuffer code.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected packages.
