CVE-2005-4459: Heap-based buffer overflow in the NAT networking components vmnat.exe and vmnet-natd in VMWare Workstation...

Heap-based buffer overflow in the NAT networking components vmnat.exe and vmnet-natd in VMWare Workstation 5.5, GSX Server 3.2, ACE 1.0.1, and Player 1.0 allows remote authenticated attackers, including guests, to execute arbitrary code via crafted (1) EPRT and (2) PORT FTP commands.

Security readout for executives and security teams

This old VMware flaw affects NAT networking used by several 2005-era VMware products. A malicious authenticated user, including someone inside a guest VM, could trigger memory corruption and potentially run code through crafted FTP commands handled by the NAT component. Exposure is most likely in legacy virtualization hosts still running the listed VMware products with NAT networking enabled. Modern environments are less likely affected unless old lab, embedded, or unsupported systems remain. Prioritize if legacy VMware hosts remain in production, labs, or sensitive networks. The risk is high where untrusted guest users can interact with NAT networking, but current exploitation evidence is not provided. Mitigation focus: Inventory for the listed VMware products and versions.; Check VMware KB 2000 and Gentoo GLSA guidance for vendor remediation.; Retire or upgrade unsupported legacy VMware installations where possible..
