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.

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.
