Microsoft Win32k Privilege Escalation Vulnerability

Microsoft · Win32k

Summary

A flaw in win32k.sys, the kernel-mode driver component of Microsoft Windows (including Windows Server 2003 through 2012 R2, Windows Vista, 7, 8, 8.1 and Windows RT), allows privilege escalation. An attacker with local, unprivileged access can gain elevated privileges by running a crafted application, and user interaction is required.
