Description

This module exploits a buffer overflow in the mIRC IRC Client v6.34 and earlier.
By enticing a mIRC user to connect to this server module, an excessively long PRIVMSG
command can be sent, overwriting the stack. Due to size restrictions, ordinal payloads
may be necessary. This module is based on the code by SkD.
