"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.

   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. 

   The Common Vulnerabilities and Exposures project (cve.mitre.org)
   has assigned the name CVE-2014-3793 to this issue."
