on the remote host is 1.10 or earlier.  Such versions suffer from
several denial of service vulnerabilities.

A remote attacker, possibly using anonymous access, can cause the
server to stop responding by sending it an 'ABOR' command without any
active file transfer in progress or can crash it by sending any one of
a number of specially crafted FTP commands."
