Description

Background

VMware Workstation is a powerful virtual machine for developers and system administrators.

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/k b, Answer ID 2002.

Resolution

All VMware Workstation users should upgrade to a fixed version:

 # emerge --sync
 # emerge --ask --oneshot --verbose app-emulation/vmware-workstation
