CVE number:  CVE-2013-3519
- -----------------------------------------------------------------------

1. Summary

    VMware Workstation, Fusion, ESXi and ESX patches address a 
    vulnerability in the LGTOSYNC.SYS driver which could result in a

3. Problem Description

   a. VMware LGTOSYNC privilege escalation.

      VMware ESX, Workstation and Fusion contain a vulnerability 
      in the handling of control code in lgtosync.sys. A local 
      malicious user may exploit this vulnerability to manipulate the 
      memory allocation. This could result in a privilege 
      escalation on 32-bit Guest Operating Systems running Windows 2000
      Server, Windows XP or Windows 2003 Server on ESXi and ESX; or 
      Windows XP on Workstation and Fusion.

      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.

      VMware would like to thank Derek Soeder of Cylance, Inc. for 
      reporting this issue to us. 

      The Common Vulnerabilityies and Exposures project (cve.mitre.org)
      has assigned the name CVE-2013-3519 to this issue.

      Column 4 of the following table lists the action required to
      remediate the vulnerability in each release, if a solution is
      available.

      * Notes on updating VMware Guest Tools:

      be updated in any pre-existing Windows-based Guest Operating 
      System followed by a reboot of the guest system.
