Unspecified vulnerability in an ioctl in hcmon.sys in VMware Workstation 6.5.1 and earlier, VMware Player 2.5.1 and earlier, VMware ACE 2.5.1 and earlier, and VMware Server 1.0.x before 1.0.9 build 156507 and 2.0.x before 2.0.1 build 156745 allows local users to cause a denial of service via unknown vectors, a different vulnerability than CVE-2008-3761.

Security readout for executives and security teams

This is an old VMware hosted-product flaw in the Windows hcmon.sys driver. A local user could trigger a denial of service through an unspecified ioctl path. The sources do not describe remote exploitation, privilege escalation, or data theft. Exposure is most likely on legacy Windows systems still running the affected VMware hosted products, especially shared workstations, lab hosts, jump boxes, or servers where non-admin local users can log in. Treat this as a legacy exposure cleanup issue, not an internet-scale emergency. It matters where old VMware products remain on shared or sensitive systems because a local user could disrupt availability. Mitigation focus: Check VMware VMSA-2009-0005 for fixed releases and supported upgrade paths.; Upgrade VMware Server to 1.0.9 build 156507 or 2.0.1 build 156745 or later.; Retire unsupported VMware Workstation, Player, ACE, or Server installations where upgrades are unavailable..
