Red Hat: cvs Chroot breakout vulnerability
Summary
Summary
CVS is a version control system frequently used to manage source coderepositories. A flaw was found in versions of CVS prior to 1.11.10 where a malformedmodule request could cause the CVS server to attempt to create files ordirectories at the root level of the file system. However, normal filesystem permissions would prevent the creation of these misplaceddirectories. The Common Vulnerabilities and Exposures project(cve.mitre.org) has assigned the name CAN-2003-0977 to this issue.Users of CVS are advised to upgrade to these erratum packages, whichcontain a patch correcting this issue.
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.

You can verify each package with the following command:
rpm --checksig -v
If you only wish to verify that each package has not been corrupted or
tampered with, examine only the md5sum with the following command:
