Updated cvs to 1.11.23-7

This update addresses the following issue:

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)
