In short
A flaw in Windows kernel driver (win32k.sys) allows someone with local access to run a specially crafted program that gives them admin-level control over the system. This was actively exploited by attackers in October 2014.
Technical detail
win32k.sys contains a privilege escalation vulnerability exploitable by local attackers through a malicious application. The vulnerability allows unprivileged users to execute code with kernel privileges, affecting multiple Windows versions from Server 2003 through Server 2012 R2 and Windows 8.1. Exploitation requires local code execution capability.
Summary generated and translated by AI from the official description.
win32k.sys in the kernel-mode drivers in Microsoft Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, and Windows RT Gold and 8.1 allows local users to gain privileges via a crafted application, as exploited in the wild in October 2014, aka "Win32k.sys Elevation of Privilege Vulnerability."
