Date:	01/07/2006
Bugs:	#116238
ID:	200601-04

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	Architecture(s)
app-emulation/vmware-workstation	< 5.5.1.19175	>= 5.5.1.19175	All supported architectures

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
