vmwarebase.dll, as used in the vmware-authd service (aka vmware-authd.exe), in VMware Workstation 6.5.1 build 126130, 6.5.1 and earlier; VMware Player 2.5.1 build 126130, 2.5.1 and earlier; VMware ACE 2.5.1 and earlier; VMware Server 2.0.x before 2.0.1 build 156745; and VMware Fusion before 2.0.2 build 147997 allows remote attackers to cause a denial of service (daemon crash) via a long (1) USER or (2) PASS command.

Security readout for executives and security teams

This is an old VMware hosted-products denial-of-service flaw. A remote attacker could crash vmware-authd by sending overly long authentication fields. The supplied evidence points to service disruption on legacy VMware Workstation, Player, ACE, Server, and Fusion installs, not data theft. Exposure is most likely in legacy environments still running affected VMware hosted products with vmware-authd reachable over a network. Modern fully patched VMware estates are unlikely to be exposed, but inventories should confirm no unsupported versions remain. Treat this as a legacy exposure cleanup item. It is not marked KEV and the known impact is denial of service, but internet- or broadly reachable vulnerable systems could be disrupted and should be upgraded or isolated. Mitigation focus: Identify affected VMware Workstation, Player, ACE, Server, and Fusion installations.; Upgrade VMware Server to 2.0.1 build 156745 or later where applicable.; Upgrade VMware Fusion to 2.0.2 build 147997 or later where applicable..
