NetCPlus SmartServer3 POP 3.51.1 EXPLOIT

Problem:

The POP server that is part of the NetcPlus SmartServer3 email server has an
unchecked buffer that could allow an attacker to execute code on the server.
If the USER command is followed by an argument of over 800 characters, the
input buffer will be overflowed, and data from the argument will be passed
to the system to be executed at the privelege level of the SmartServ
program.
