Xen是英国剑桥大学开发的一款开源的虚拟机监视器产品。该产品能够使不同和不兼容的操作系统运行在同一台计算机上，并支持在运行时进行迁移，保证正常运行并且避免宕机。 Xen 3.4, 4.0,以及4.1中存在漏洞。该漏洞源于当guest系统没有为系统调用和系统进入注册处理程序的情况下，Xen在注入一般性保护错误时没有正确地清理异常注入的标志。具备PV geust系统用户权限的本地攻击者可通过稍后触发一个一般会在Xen内部处理的异常造成拒绝服务（guest崩溃）。

Source: CVE Program / CVE List V5
Vulnerability Description
Xen 3.4, 4.0, and 4.1, when the guest OS has not registered a handler for a syscall or sysenter instruction, does not properly clear a flag for exception injection when injecting a General Protection Fault, which allows local PV guest OS users to cause a denial of service (guest crash) by later triggering an exception that would normally be handled within Xen.
