tag_summary = "The remote CVS server, according to its version number, might allow an 
attacker to execute arbitrary commands on the remote system because of
a flaw relating to malformed Entry lines which lead to a
missing NULL terminator.

Among the issues deemed likely to be exploitable were:

- a double-free relating to the error_prog_name string (CVE-2004-0416)
- an argument integer overflow (CVE-2004-0417)
- out-of-bounds writes in serv_notify (CVE-2004-0418)";

tag_solution = "Upgrade to CVS 1.12.9 or 1.11.17";
