                  VMware Security Advisory

Advisory ID: VMSA-2013-0010
Synopsis:    VMware Workstation host privilege escalation vulnerability
Issue date:  2013-08-22
Updated on:  2013-08-22 (initial advisory)
CVE numbers: CVE-2013-1662

- ------------------------------------------------------------------------

1. Summary

  VMware Workstation and VMware Player address a vulnerability in the
  vmware-mount component which could result in a privilege escalation
  on linux-based host machines.

2. Relevant releases

  VMware Workstation 9.x
  VMware Workstation 8.x
VMware Player 5.x
  VMware Player 4.x

3. Problem Description

  a. VMware mount privilege escalation

     VMware Workstation and Player contain a vulnerability in the
     handling of the vmware-mount command. A local malicious user may
     exploit this vulnerability to escalate their privileges to root on
     the host OS. The issue is present when Workstation or Player are
     installed on a Debian-based version of Linux.

     The vulnerability does not allow for privilege escalation from the
     Guest Operating System to the host or vice-versa. This means that
     host memory can not be manipulated from the Guest Operating
     System.

     Workaround
     A workaround for the issue is to remove the setuid bit from
     vmware-mount:
# chmod u-s /usr/bin/vmware-mount This workaround is relevant for both Workstation and Player.

     VMware would like to thank Tavis Ormandy from the Google Security
     Team for reporting this issue to us.

     The Common Vulnerabilities and Exposures project (cve.mitre.org)
