Descriptions

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 or cause a denial of service (NULL pointer dereference) via a crafted application, aka "Win32k Elevation of Privilege Vulnerability."

win32k.sys en los controladores del modo kernel en Microsoft Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2 y R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold y R2, y Windows RT Gold y 8.1 permite a usuarios locales ganar privilegios o causar una denegación de servicio (referencia a puntero nulo) a través de un aplicación manipulada, también conocido como 'vulnerabilidad de la elevación de privilegios de Win32k.'

This vulnerability allows local attackers to elevate to System privileges on vulnerable installations of Microsoft Windows. This vulnerability requires the ability to run arbitrary unprivileged code.
The specific flaw exists within the handling of the WM_SYSTIMER message. By malforming the window handle in the message, an attacker is able to cause the kernel to write to a controlled address. An attacker could leverage this to execute arbitrary code in the context of the System.
