Security Advisory

1) Privilege escalation


The vulnerability allows a local attacker to obtain elevated privileges on the target system.

The weakness exists due to improper handling of objects in memory by kernel-mode driver (win32k.sys). A local attacker can run a specially crafted application to gain elevated privileges and take complete control of the system.

Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.

Note: the vulnerability was being actively exploited.
