Vulnerability Name:

CCN-99087

Published:2014-11-22
Updated:2014-11-22
Summary:Microsoft Windows is vulnerable to a denial of service, caused by the failure to validate the result of win32k!xxxMNOpenHierarchy properly by the win32k!xxxMenuWindowProc function within the kernel-mode driver (win32k.sys). By running a specially-crafted application, a local attacker could exploit this vulnerability to cause the system to stop responding.
