Microsoft: Windows Win32k Elevation of Privilege Vulnerability
An elevation of privilege vulnerability exists when Windows improperly handles calls to Win32k.sys. An attacker who successfully exploited the vulnerability could gain elevated privileges on a targeted system. To exploit the vulnerability, an attacker would have to log on to an affected system and run a specially crafted script or application. The update addresses the vulnerability by correcting how Windows handles calls to Win32k.
