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. ';
