An updated cvs package that fixes a server vulnerability that could be exploited by a malicious client is now available.
CVS is a version control system frequently used to manage source code repositories. 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 CAN-2004-0396 to this issue. Users of CVS are advised to upgrade to this updated package, which contains a backported patch correcting this issue. Red Hat would like to thank Stefan Esser for notifying us of this issue and Derek Price for providing an updated patch.
