Descriptions

Windows kernel in Windows 7 SP1, Windows Server 2008 SP2 and R2 SP1, Windows 8.1 and RT1, Windows Server 2012 and R2, Windows 10 Gold, 1511, 1607, 1703, and 1709, Windows Server 2016, and Windows Server, version 1709 allows an attacker to run arbitrary code in kernel mode, install programs, view, change or delete data, and create new accounts with full user rights due to improperly handing objects in memory, aka "Windows Kernel Elevation of Privilege Vulnerability".

El kernel de Windows en Windows 7 SP1, Windows Server 2008 SP2 y R2 SP1, Windows 8.1 y RT1, Windows Server 2012 y R2, Windows 10 Gold, 1511, 1607, 1703 y 1709, Windows Server 2016, y Windows Server en su versión 1709 permite que un atacante ejecute código arbitrario en modo kernel; instale programas; visualice, cambie o elimine datos; y cree nuevas cuentas con todos los derechos de usuario debido a que se gestionan de manera incorrecta los objetos en la memoria. Esta vulnerabilidad también se conoce como "Windows Kernel Elevation of Privilege Vulnerability".

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.
The specific flaw exists within the handling of menus in the win32k driver. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to escalate privileges to the level of SYSTEM.
