mount.vmhgfs in the VMware Host Guest File System (HGFS) in VMware Workstation 7.1.x before 7.1.4, VMware Player 3.1.x before 3.1.4, VMware Fusion 3.1.x before 3.1.3, VMware ESXi 3.5 through 4.1, and VMware ESX 3.0.3 through 4.1 allows guest OS users to determine the existence of host OS files and directories via unspecified vectors.

The installer in VMware Workstation 7.x before 7.1.2 build 301548 and VMware Player 3.x before 3.1.2 build 301548 renders an index.htm file if present in the installation directory, which might allow local users to trigger unintended interpretation of web script or HTML by creating this file.
