Topic: Updated XFree86 packages for Red Hat Linux 8.0 are now available which include several security fixes, bug fixes, enhancements, and driver updates. 2. Relevant releases/architectures: Red Hat Linux 8.0 - i386 3. Problem description: XFree86 is an implementation of the X Window System providing the core graphical user interface and video drivers in Red Hat Linux. A number of security vulnerabilities have been discovered in XFree86 4.2.0: - - Xterm, provided as part of the XFree86 packages, provides an escape sequence for reporting the current window title. This escape sequence essentially takes the current title and places it directly on the command line. An attacker can craft an escape sequence that sets the victim's Xterm window title to an arbitrary command, and then reports it to the command line. Since it is not possible to embed a carriage return into the window title, the attacker would then have to convince the victim to press Enter for the shell to process the title as a command, although the attacker could craft other escape sequences that might convince the victim to do so. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0063 to this issue. - - It is possible to lock up versions of Xterm by sending an invalid DEC UDK escape sequence. (CAN-2003-0071) - - XFree86 4.2.1 also contains an updated fix for CAN-2002-0164, a vulnerability in the MIT-SHM extension of the X server that allows local users to read and write arbitrary shared memory. The original fix did not cover the case where the X server is started from xdm. - - The X server was setting the /dev/dri directory permissions incorrectly, which resulted in the directory being world writable. It now sets the directory permissions to a safe value. (CAN-2001-1409) Driver updates and additions: - - Savage driver updated to Tim Roberts' latest version 1.1.27t. - - Added new "cyrix" driver from Alan Cox, which works much better on MediaGX hardware. - - Added new input drivers from Alan Cox for Fujitsu Stylistic (fpit), Palmax PD1000/PD1100 Input driver (palmax), Union Reality UR-98 head tracker (ur98) - - Backported apm driver from XFree86 CVS, DPMS support enhancements, and a few accel fixes - - Backported ark driver from XFree86 CVS - - Backported chips driver from XFree86 CVS, with hardware mouse cursor and 2D accleration fixes. - - Backported cirrus i740, siliconmotion, and ark drivers from XFree86 CVS Various bug fixes and enhancements: - - Bug fixes for the RENDER extension and libraries which improve stability - - Various fixes to the Xaw library - - A long standing problem in the X server has been fixed in which the mouse, keyboard, or video would hang, or the server to go into an endless loop whenever the system time was changed backward while X was running - - Fixed a bug in both the Radeon and Rage 128 drivers which caused crashes while using VMware with DGA when DRI is enabled - - The Matrox "mga" driver had some problems with multihead and the RENDER extension which have been worked around. - - fc-cache is now run upon font package installation in all font directories containing fonts managed by fontconfig/Xft - - mkfontdir has been modified to force the permissions of the files it generates to be mode 0644 ensuring they are world readable independant of umask. - - Added a new option "ForceLegacyCRT" to the radeon driver to allow use of legacy VGA monitors which can not be detected automatically. This option is only safe to use in single-head setups and may cause serious problems if used with dual-head. - - xterm session management is now enabled by default, whereas the stock XFree86 default in 4.2.0/4.2.1 was accidentally disabled upstream - - Removed and obsoleted the XFree86-xtrap-clients package, and merged it into the main XFree86 package to simplify packaging There are various other fixes included which users can review by examining the RPM package changelog of any of the new XFree86 packages. Users are advised to upgrade to these updated XFree86 4.2.1 packages, which are not vulnerable to the previously mentioned security issues. 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 Red Hat Network. Many people find this an easier way to apply updates. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. 5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info): 63509 - mouse event problems after system standby 69978 - Radeon failure with old VGA monitor 72297 - MediaGX 5530 XFree86 failure 73678 - Screen corruption when running full-screen VMware under DRI-enabled XFree86 75155 - lndir doesn't work with relative symlink 76154 - Mozilla with xft crashes on Red Hat 8.0 (Xrender bug) 77542 - XFree86-truetype-fonts does integrate with Xft/fontconfig 77930 - rhPrintOSKernelString can print stack garbage 78804 - Xutf8LookupString fails in UTF-8 locale if X server lacks XKB support 79488 - XKeysymDB is included in XFree86.rpm whereas it should be in XFree86-libs.rpm 83303 - Unresolved DRM symbols in r128 driver (4.2.1) 84036 - xauth can write incomplete .xauth files 88773 - xterm session management is disabled by default in XFree86 4.2.x 6.
