Nothing specific?  Then please try the SAINT people for info.

If the ftpd server is vulnerable if anonymous is allowed, it usually
means its vulnerable if "at least" anonymous is allowed.  Usually
its "even worse" if other logins are available.

The two bugs I do know about, which got fixed in OpenBSD over the
last year, are the setproctitle() bug, and the replydirname() bug.

Are there any others?

The version in potato (just apt-get source ftpd now), does not
contain the replydirname() function at all, and setproctitle() seems
fine.  Disclaimer applies.

Someone correct me if I am wrong...

Maybe nessus?
