This could be used to DoS a remote machine and in some cases execute code remotely. Lets look at the following example attack. The server must either have anonymous access rights or an attacker must have an account. 200 PORT command successful. The above example uses 316 characters to overflow.

The instruction at '0x710f8aa2' referenced memory at '0x41414156'. The memory could not be 'read'. Connection closed by remote host. Lets take a look once again at the server side. This is looking mighty interesting.
