VMware Workstation: Vulnerability in NAT networking VMware guest operating systems can execute arbitrary code with elevated privileges on the host operating system through a flaw in NAT networking. VMware January 07, 2006 May 25, 2006: 02 116238 remote and local 5.5.1.19175 4.5.3.19414 3.2.1.2242-r10 5.5.1.19175

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:
