  <description>
    <p>
    Tim Shelton discovered that vmnet-natd, the host module providing
    NAT-style networking for VMware guest operating systems, is unable to
    process incorrect 'EPRT' and 'PORT' FTP requests.
    </p>
  </description>
  <impact type="high">
    <p>
    Malicious guest operating systems using the NAT networking feature or
    local VMware Workstation users could exploit this vulnerability to
    execute arbitrary code on the host system with elevated privileges.
    </p>
  </impact>
  <workaround>
    <p>
    Disable the NAT service by following the instructions at <uri
    link="http://www.vmware.com/support/kb">http://www.vmware.com/support/k
    b</uri>, Answer ID 2002.
    </p>
  </workaround>
  <resolution>
    <p>
    All VMware Workstation users should upgrade to a fixed version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose app-emulation/vmware-workstation</code>
  </resolution>
