    1) Introduction
    ===============

    Terminator 3: War of the Machines is a multiplayer FPS game developed

    2) Bugs
    =======

    ------------------------------
    A] cd-key hash buffer-overflow
    ------------------------------

    The text field containing the client cd-key hash is the cause of a
    buffer-overflow that affects the server.
    Note: this is NOT the Gamespy cd-key SDK buffer-overflow.

    --------------------------------
    B] big nickname access violation
    --------------------------------

    If an attacker uses a too big nickname the server crashes for the
    access to an arbitrary zone of the memory.

    The game is no longer supported.
