[原文]Buffer overflow in xconq 7.4.1 allows local users to become part of the "games" group via the (1) USER or (2) DISPLAY environment variables.


[CNNVD]XConq多个环境变量缓冲区溢出漏洞(CNNVD-200403-131)

        
        Xconq是一个普通的策略型游戏系统。
        Xconq在处理USER和DISPLAY环境变量时缺少充分边界缓冲区检查,本地攻击者可以利用这个漏洞进行缓冲区溢出攻击,可能以games组权限在系统上执行任意指令。
        攻击者设置USER和DISPLAY环境变量包含超长字符串,执行Xconq可触发漏洞,精心构建提交数据可能以games组权限在系统上执行任意指令。

- 漏洞讨论

Multiple locally exploitable buffer overflows have been reported in xconq. This is due to insufficient bounds checking of data supplied via the USER and DISPLAY environment variables, and could allow execution of code in the context of the program, which is typically installed setgid 'games'.

This issue appears similar to BID 1495.
