DESCRIPTION:
Neil Kettle has discovered a vulnerability in DESlock+, which can be
exploited by malicious, local users to gain escalated privileges.
The vulnerability is caused due to the vdlptokn.sys kernel driver not
properly validating a certain pointer in a structure. This can be
exploited to execute arbitrary code with SYSTEM privileges via a
specially crafted IOCTL sent to the affected driver.
The vulnerability is reported in version 3.2.7 and confirmed in
version 4.1.12. Other versions may also be affected.
SOLUTION:
Restrict access to trusted users only.
