Description :

a. Guest privilege escalation in VMware Tools

A kernel NULL dereference vulnerability was found in VMware
Tools running on Microsoft Windows 8.1. Successful exploitation

guest operating system.

VMware would like to thank Tavis Ormandy from the Google Security
Team for reporting this issue to us.

The vulnerability does not allow for privilege escalation from
the Guest Operating System to the host. This means that host
memory can not be manipulated from the Guest Operating System.
