1. Topic:
Updated cvs packages that fix a client vulnerability that could be
exploited by a malicious server are now available.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64
Red Hat Linux Advanced Workstation 2.1 - ia64
Red Hat Enterprise Linux ES version 2.1 - i386
Red Hat Enterprise Linux WS version 2.1 - i386

3. Problem description:
CVS is a version control system frequently used to manage source code
repositories.
Sebastian Krahmer discovered a flaw in CVS clients where rcs diff files can
create files with absolute pathnames. An attacker could create a fake
malicious CVS server that would cause arbitrary files to be created or
overwritten when a victim connects to it. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CAN-2004-0180 to
this issue.
Users of CVS are advised to upgrade to these erratum packages, which
contain a patch correcting this issue.
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.
