Concurrent Version System (CVS) is a version control system that can record the history of your files.
A heap-based buffer overflow flaw was found in the way the CVS client handled responses from HTTP proxies. A malicious HTTP proxy could use this flaw to cause the CVS client to crash or, possibly, execute arbitrary code with the privileges of the user running the CVS client.
(CVE-2012-0804)
All users of cvs are advised to upgrade to these updated packages, which contain a patch to correct this issue.
