[原文]Buffer overflow in aGSM Half-Life client allows remote Half-Life servers to cause a denial of service (crash) and possibly execute arbitrary code via a long server response.


[CNNVD]aGSM远程缓冲区溢出漏洞(CNNVD-200412-976)

        
        aGSM是游戏服务器监视程序,可快速找寻和监视游戏服务器状态。
        aGSM不正确验证半条命服务程序的应答,远程攻击者可以利用这个漏洞进行缓冲区溢出攻击。
        远程半条命服务器可以构建特殊应答,造成aGSM缓冲区溢出,精心构建应答数据可能以进程权限在系统上执行任意指令。

source: http://www.securityfocus.com/bid/10989/info

aGSM is reported prone to a remote buffer overflow vulnerability. The issue presents itself in the aGSM server information parsing routines for Half-Life game servers. Due to a lack of sufficient bounds checking performed on the hostname parameter in a server reply to an info request, a malicious server may execute arbitrary code on an affected client.

It should be noted that although aGSM version 2.35c is reported prone to this vulnerability, other versions might also be affected.

For the following query:
\xFF\xFF\xFF\xFFinfo\x00
The following response is sent:
\xff\xff\xff\xffA\x00AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA

aGSM Half-Life Server Response Remote Overflow
Remote / Network Access Input Manipulation
Loss of Integrity
Exploit Unknown

- 漏洞描述

A remote overflow exists in aGSM. The program fails to validate the responses from Half-Life servers resulting in a buffer overflow condition. With a specially crafted request, an attacker can cause an overflow and execute arbitrary code on the system, resulting in a loss of integrity.
