Red Hat: 2012:0321-01: cvs: Moderate Advisory
Summary
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.
