Problem 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 of this issue could lead to an escalation of privilege in the guest operating system.

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.
