tag_summary = "WarFTPd is prone to multiple remote format-string vulnerabilities
because the application fails to sanitize user-supplied input before
passing it to a formatted-output function.

An attacker can exploit these issues to crash the server and possibly
to execute arbitrary code within the context of the server, but this
has not been confirmed.

WarFTPd 1.82.00-RC11 is reported vulnerable; prior versions may be
vulnerable as well.";
