RHSA-2004:152 - Security Advisory

Topic

Updated XFree86 packages that fix a minor denial of service vulnerability are
now available.

Description

XFree86 is an implementation of the X Window System, providing the core
graphical user interface and video drivers.

Flaws in XFree86 4.1.0 allows local or remote attackers who are able to
connect to the X server to cause a denial of service via an out-of-bounds
array index or integer signedness error when using the GLX extension and
Direct Rendering Infrastructure (DRI). The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the names CAN-2004-0093 and
CAN-2004-0094 to these issues.

These issues do not affect Red Hat Enterprise Linux 3.

All users of XFree86 are advised to upgrade to these erratum packages,
which contain a backported fix and are not vulnerable to these issues.

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.

If up2date fails to connect to Red Hat Network due to SSL Certificate
Errors, you need to install a version of the up2date client with an updated
certificate. The latest version of up2date is available from the Red Hat
FTP site and may also be downloaded directly from the RHN website:
