Windows Graphics Device Interface (GDI) en Microsoft Windows Server 2008 SP2 y R2 SP1 y Windows 7 SP1 permite una vulnerabilidad de elevación de privilegios debido a la forma en la que se gestionan los objetos en la memoria. Esto también se conoce como "Windows GDI Elevation of Privilege Vulnerability". El ID de este CVE es diferente de CVE-2018-0816 y CVE-2018-0817.

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 win32k.sys driver. When handling a palette object, a race condition exists due to the failure to lock an object in memory between operations. An attacker can leverage this vulnerability to escalate privileges to the level of SYSTEM.
