Microsoft Windows Uninitialized Variable Local Privilege Elevation

This module exploits CVE-2019-1458, an arbitrary pointer dereference vulnerability
within win32k which occurs due to an uninitalized variable, which allows user mode attackers
to write a limited amount of controlled data to an attacker controlled address
in kernel memory. By utilizing this vulnerability to execute controlled writes
to kernel memory, an attacker can gain arbitrary code execution
as the SYSTEM user.

This module has been tested against Windows 7 x64 SP1. Offsets within the
exploit code may need to be adjusted to work with other versions of Windows.
The exploit can only be triggered once against the target and can cause the
target machine to reboot when the session is terminated.
