Fedora Core 3 : xorg-x11-6.8.2-1.FC3.45 (2005-893)

Medium Nessus Plugin ID 19739


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 3.

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 change to the X server to make it use linux PCI config space access methods instead of directly touching the PCI config space registers itself. This prevents the X server from causing hardware lockups due accessing PCI config space at the same time the kernel has it locked.
This is the latest revision of the PCI config space access patches, which fix a few regressions discovered on some hardware with previous patches.

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

- A problem with the Dutch keyboard layout has been resolved.

- The open source 'nv' driver for Nvidia hardware has been updated to the latest version. Additionally, a workaround has been added to the driver to disable known unstable acceleration primitives on some GeForce 6200/6600/6800 models.

- Several bugs have been fixed in the Xnest X server.

- DRI is now enabled by default on all ATI Radeon hardware except for the Radeon 7000/Radeon VE chipsets, which is known to be unstable for many users currently when DRI is enabled. Radeon 7000 users can re-enable DRI if desired by using Option 'DRI' in the device section of the config file, with the understanding that we consider it unstable currently.

- Added missing libFS.so and libGLw.so symlinks to the xorg-x11-devel package, which were inadvertently left out, causing apps to link to the static versions of these libraries.

- Fix xfs.init 'fonts.dir: No such file or directory' errors

A number of other issues have also been resolved. Please consult the xorg-x11 rpm changelog for a detailed list.

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.
