Microsoft: Win32k Information Disclosure Vulnerability
An information disclosure vulnerability exists when the win32k component improperly provides kernel information. An attacker who successfully exploited the vulnerability could obtain information to further compromise the user s system. To exploit the vulnerability, an attacker would have to either log on locally to an affected system, or convince a locally authenticated user to execute a specially crafted application. The security update addresses the vulnerability by correcting how win32k handles objects in memory.
