(RHSA-2004:153) cvs security update

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.

Derek Price discovered a vulnerability whereby a CVS pserver could be
abused by a malicious client to view the contents of certain files outside
of the CVS root directory using relative pathnames containing “…/”. The
Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
the name CAN-2004-0405 to this issue.

Users of CVS are advised to upgrade to these erratum packages, which
contain a patch correcting this issue.
