[原文]Buffer overflow in Painkiller 1.3.1 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long password.


[CNNVD]People Can Fly Painkiller远程缓冲区溢出漏洞(CNNVD-200408-218)

        Painkiller 1.3.1及其早期版本存在缓冲区溢出漏洞。远程攻击者借助超长密码导致服务拒绝(崩溃)和可能执行任意代码。

Painkiller packet's password encoder/decoder 0.1 
by Luigi Auriemma 
e-mail: aluigi@altervista.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: %sn", pwd);   // the password is "mypassword"
