Descriptions

The Graphics component in the kernel in Microsoft Windows Vista SP2; Windows Server 2008 SP2 and R2 SP1; and Windows 7 SP1 allows local users to gain privileges via a crafted application, aka "Windows Graphics Elevation of Privilege Vulnerability."

El componente Graphics en el kernel en Microsoft Windows Vista SP2; Windows Server 2008 SP2 y R2 SP1; y Windows 7 SP1 permite a usuarios locales obtener privilegios a través de una aplicación manipulada, vulnerabilidad también conocida como "Vulnerabilidad de elevación de privilegios de gráficos de Windows".

This vulnerability allows local attackers to escalate privileges on vulnerable installations of Microsoft Windows. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
