Xen 差一错误漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
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 4.2.x和4.3.x版本中的xsm/flask/flask_op.c文件的‘flask_security_avc_cachestats’函数中存在差一错误漏洞。当使用物理CPU的大量资源时，本地攻击者可通过FLASK_AVC_CACHESTAT超级调用利用该漏洞造成拒绝服务（主机崩溃）或获取管理程序内存的敏感信息。
