  A kernel NULL dereference vulnerability was found in VMware Tools

  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.");
