I concur, incidentally recently posted at:

ProFTPD

The ProFTPD FTP daemon is vulnerable to a denial-of-service attack and a
problem in resolving some host names properly. The denial-of-service
attack can be
used by a remote attacker to cause ProFTPD to consume all of the CPU and
memory on the server. The resolution problem is caused by ProFTPD not
properly
forward-resolving reverse-resolved host names, and could be used by an
attacker to get around ProFTPD access control lists or to log incorrect
host names.

Users should consider upgrading ProFTPD to version 1.2.5rc1 or newer.
