VMware Workstation is a powerful virtual machine for developers and system administrators.
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.
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.
Disable the NAT service by following the instructions at http://www.vmware.com/support/k b, Answer ID 2002.
All VMware Workstation users should upgrade to a fixed version:
# emerge --sync # emerge --ask --oneshot --verbose app-emulation/vmware-workstation
