[原文]Buffer overflow in Painkiller 1.35 and earlier, and possibly other versions before 1.61, allows remote authenticated users to cause a denial of service and possibly execute arbitrary code via a long cd-key hash.

Painkiller packet's password encoder/decoder 0.1
by Luigi Auriemma
e-mail: aluigi@autistici.org
web:    http://aluigi.altervista.org


INTRODUCTION
============
When you want to join a password protected game server of Painkiller
(http://www.painkillergame.com) your client sends a packet containing
the packet ID (0x04), your client version, the 72 bytes of the Gamespy
auth key (http://aluigi.altervista.org/papers/gskey-auth.txt) plus a
"strange" text string after it.
This text string is just the password you have used to join and it is
encrypted using the other text string (the server challenge) sent by
the server in its previous packet.
My optimized algorithm is able to decode/encode the password stored in
the packet sent by the client.


HOW TO USE
==========
The function is an algorithm used for both encoding and decoding
without differences.
It needs only 2 parameters:
- pwd: the client's password stored in the packet
- enc: the server challenge string

Example:
  #include "painkiller_pckpwd.h"

    unsigned char   pwd[] = "5mjblOpV8N",
                    enc[] = "k7bEv4cGcw";
    painkiller_pckpwd(pwd, enc);
    printf("Password: %s\n", pwd);  // the password is "mypassword"
