[原文]init_dev in tty_io.c in the Red Hat backport of NPTL to Red Hat Enterprise Linux 3 does not properly clear controlling tty's in multi-threaded applications, which allows local users to cause a denial of service (crash) and possibly gain tty access via unknown attack vectors that trigger an access of a pointer to a freed structure.


[CNNVD]Red Hat Linux init_dev拒绝服务漏洞(CNNVD-200509-002)

        Red Hat Enterprise Linux是由Red hat公司维护和发布的面向企业用户的Linux操作系统。
        从RedHat NPTL除错修补程序到RedHat企业版3,tty_io.c 的init_dev均不能正确地清除多线程应用程序中的控制tty设备。这使得本地用户可以导致服务拒绝(崩溃)并且可能借助未明媒介访问tty设备。所述未明媒介触发对指向一个释放结构的指针的访问。
