"Stefan Esser discovered a flaw in cvs where malformed 'Entry' lines
could cause a heap overflow. An attacker who has access to a CVS
server could use this flaw to execute arbitrary code under the UID
which the CVS server is executing. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CVE-2004-0396
to this issue.

This update includes a patch by Derek Price, based on a patch by
Stefan Esser, which corrects this flaw.

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
