Less critical

IMPACT:
Privilege escalation

DESCRIPTION:
Ryu Connor has reported a vulnerability in nProtect Gameguard, which
potentially can be exploited by malicious, local users to perform
certain actions on a vulnerable system with escalated privileges.

The vulnerability is caused due to a design error in the npptnt2.vxd
driver, which allows unrestricted low level I/O in user mode from any
process. This may e.g. be exploited to modify arbitrary files on the
hard drive.

SOLUTION:
Grant only trusted users access to affected systems.
