TITLE
    Call of Duty <= 1.5b / UO <= 1.51b and Call of Duty 2 1.0 buffer-overrun fix 0.1 (Windows)

INTRO
    This unofficial patch is referred to the bug described here:
    .
    . http://aluigi.org/adv/codmsgboom-adv.txt
    .
    If you are unsure if your server is vulnerable please use the proof-of-concept
    provided there.
    .
    This patch searchs for a byte (yes, only one) to modify in any given executable
    of Call of Duty / UO / Call of Duty 2 and old versions too.
    .
    The patch consists in reducing the threshold used by the server to drop the
    client strings from 1024 to 896 avoiding the sprintf() buffer-overflow.
    .
    The dll to patch is game_mp_x86.dll for CoD or uo_game_mp_x86.dll for CoDUO.
    On CoD2 you simply need to select the CoD2MP_s.exe file.
    If you have some mods installed you need to patch ALL their dlls.
    They are located in the .pk3 files so you need to extract the needed dll from
    the zipped pk3 files of your mods and then re-zip them... anyway I think you
    already know these things better than me.
    If you use only the normal game without mods you need to patch only the dll
    in your Main folder (in case of problems the dll in the pak*.pk3 with the
    higher number).
