[原文]Buffer overflow in socket/request.c in CrossFire before 1.9.0, when oldsocketmode is enabled, allows remote attackers to cause a denial of service (segmentation fault) and possibly execute code by sending the server a large request.


[CNNVD]CrossFire 'socket/request.c'缓冲区溢出漏洞(CNNVD-200603-067)

        CrossFire before 1.9.0的socket/request.c中的缓冲区溢出, 当oldsocketmode被允许时,允许远程攻击者制造拒绝服务(段错误)和可能通过向服务器发送大量请求执行代码。
