VMware Emulation Flaw x64 Guest Privilege Escalation (2/2)

IMPACT
------
By exploiting either of the VMware flaws described in this document,
user-mode code executing in a virtual machine may gain kernel
privileges within the virtual machine, dependent upon the guest
operating system.  The flaws have been proven exploitable on x64
versions of Windows, and they have produced potentially exploitable
crashes on x64 versions of *BSD.  The Linux kernel does not allow
exploitation of these flaws on x64 versions of Linux.

FreeBSD Security Advisory FreeBSD-SA-08:07.amd64

FreeBSD/amd64 is commonly used on 64bit systems with AMD and Intel
CPU's.  For Intel CPU's this architecture is known as EM64T or Intel
64.

The gs segment CPU register is used by both user processes and the
kernel to convieniently access state data.  User processes use it to
manage per-thread data, and the kernel uses it to manage per-processor
data.  As the processor enters and leaves the kernel it uses the
'swapgs' instruction to toggle between the kernel and user values for
the gs register.

 Problem Description:

Multiple vulnerabilities in SUPERAntiSpyware and Super Ad Blocker

VULNERABILITIES DESCRIPTION AND TECHNICAL DETAILS:
---------------

SUPERAntiSpyware and Super Ad Blocker have almost identical device
drivers in order to set up hooks and perform other duties from kernel
space. These device drivers suffer from lack of validation of
parameters passed from user mode. Additionally, some of the functions
accessible from user mode are inherently insecure and lead to easy
privilege escalation. All vulnerabilities are applicable to both
applications.
