Descriptions
The process-initialization implementation in win32k.sys in the kernel-mode drivers in Microsoft Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, Windows RT Gold and 8.1, and Windows 10 does not properly constrain impersonation levels, which allows local users to gain privileges via a crafted application, aka "Win32k Elevation of Privilege Vulnerability."
Vulnerabilidad en la implementación process-initialization en win32k.sys en los controladores kernel-mode en Microsoft Windows 8, Windows 8.1, Windows Server 2012 Gold y R2, Windows RT Gold and 8.1 y Windows 10, no restringe adecuadamente los niveles de suplantación, lo que permite a usuarios locales obtener privilegios a través de una aplicación manipulada, también conocida como 'Win32k Elevation of Privilege Vulnerability.'
The NtUserGetClipboardAccessToken win32k system call exposes the access token of the last user to lower-privileged users. It can also be used to open an anonymous impersonation thread token which normally OpenThreadToken shouldn't be able to do. This is a bypass of the fix for CVE-2015-0078.
