[原文]Buffer overflow in Orbz 2.10 and earlier allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a long password field in a join request.


[CNNVD] 21-6.com Orbz 缓冲区溢出漏洞 (CNNVD-200501-166)

        Orbz是一款3D游戏。
        Orbz 2.10以及之前版本中存在缓冲溢出漏洞。
        远程的攻击者可通过包含超长password字段的join请求导致应用系统崩溃,形成拒绝服务,也可能执行任意代码。

12164
Orbz Authentication Password Field Remote Overflow
Remote / Network Access Input Manipulation
Loss of Integrity
Exploit Public

- 漏洞描述

A remote overflow exists in Orbz. The Orbz server fails to check the length of a password field used for authentication, resulting in a buffer overflow. With a specially crafted request, an attacker can cause arbitrary code execution resulting in a loss of integrity.
