Synopsis
========
VMware guest operating systems can execute arbitrary code with elevated
privileges on the host operating system through a flaw in NAT
networking.
Background
==========
VMware Workstation is a powerful virtual machine for developers and
system administrators.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 vmware-workstation < 5.5.1.19175 >= 5.5.1.19175
*>= 4.5.3.19414
Description
===========
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.
Impact
======
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.
Workaround
==========
Disable the NAT service by following the instructions at
http://www.vmware.com/support/kb, Answer ID 2002.
Resolution
==========
All VMware Workstation users should upgrade to a fixed version:
# emerge --sync
# emerge --ask --oneshot --verbose app-emulation/vmware-workstation
