Title: VMware Workstation: Vulnerability in NAT networking (GLSA 200601-04)
Exploitable: remote and local
Date: January 07, 2006
Updated: May 25, 2006
VMware guest operating systems can execute arbitrary code with elevated privileges on the host operating system through a flaw in NAT networking.
VMware Workstation is a powerful virtual machine for developers and system administrators.
Vulnerable: < 126.96.36.19975
Unaffected: >= 188.8.131.5275
Unaffected: >= 184.108.40.20614 < 220.127.116.1115
Unaffected: >= 18.104.22.1682-r10 < 22.214.171.1243
Architectures: All supported architectures
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/kb , Answer ID 2002.
All VMware Workstation users should upgrade to a fixed version:
|# emerge --sync
# emerge --ask --oneshot --verbose app-emulation/vmware-workstation
