BUGTRAQ  ID: 32168
CVE(CAN) ID: CVE-2008-4915

VMWare是一款虚拟PC软件，允许在一台机器上同时运行两个或多个Windows、DOS、LINUX系统。

VMWare在处理指令的执行时存在问题，攻击者可能利用此漏洞提升自己的权限。如果在设置了Trap Flag的情况下出现中断，正确的CPU将执行转移到中断处理器之前会清除Trap Flag。对于受影响的VMware版本，如果内核态IRET设置了Trap Flag的话，则在执行单字节INT 3指令的时候Trap Flag在模式切换后仍继续存在，这造成的结果就是如果能够导致内核通过IRET设置Trap Flag的话，用户态代码在遇到INT 3断点（#BP）处理器的第一个指令的话会导致出现单步调试trap（#DB）。
