Unspecified vulnerability in the VMware Descheduled Time Accounting driver in VMware Workstation 6.5.1 and earlier, VMware Player 2.5.1 and earlier, VMware ACE 2.5.1 and earlier, VMware Server 1.x before 1.0.9 build 156507 and 2.x before 2.0.1 build 156745, VMware Fusion 2.x before 2.0.2 build 147997, VMware ESXi 3.5, and VMware ESX 3.0.2, 3.0.3, and 3.5, when the Descheduled Time Accounting Service is not running, allows guest OS users on Windows to cause a denial of service via unknown vectors.

Unspecified vulnerability in vmci.sys in the Virtual Machine Communication Interface (VMCI) 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 2.0.x before 2.0.1 build 156745 allows local users to gain privileges via unknown vectors.

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.

Format string vulnerability in VMware Workstation 4.5.2 build-8848, if running with elevated privileges, might allow local users to execute arbitrary code via format string specifiers in command line arguments. NOTE: it is not clear if there are any default or typical circumstances under which VMware would be running with privileges beyond those already available to the attackers, so this might not be a vulnerability.
