Unspecified vulnerability in a guest virtual device driver in VMware Workstation before 5.5.9 build 126128, and 6.5.1 and earlier 6.x versions; VMware Player before 1.0.9 build 126128, and 2.5.1 and earlier 2.x versions; VMware ACE before 1.0.8 build 125922, and 2.5.1 and earlier 2.x versions; VMware Server 1.x before 1.0.8 build 126538 and 2.0.x before 2.0.1 build 156745; VMware Fusion before 2.0.1; VMware ESXi 3.5; and VMware ESX 3.0.2, 3.0.3, and 3.5 allows guest OS users to cause a denial of service (host OS crash) via unknown vectors.

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.

Untrusted search path vulnerability in vmware-authd in VMware Workstation 5.x before 5.5.7 build 91707 and 6.x before 6.0.4 build 93057, VMware Player 1.x before 1.0.7 build 91707 and 2.x before 2.0.4 build 93057, and VMware Server before 1.0.6 build 91891 on Linux, and VMware ESXi 3.5 and VMware ESX 2.5.4 through 3.5, allows local users to gain privileges via a library path option in a configuration file.

Heap-based buffer overflow in the VMware Host Guest File System (HGFS) in VMware Workstation 6 before 6.0.4 build 93057, VMware Player 2 before 2.0.4 build 93057, VMware ACE 2 before 2.0.2 build 93057, and VMware Fusion before 1.1.2 build 87978, when folder sharing is used, allows guest OS users to execute arbitrary code on the host OS via unspecified vectors.

Unspecified vulnerability in VMCI in VMware Workstation 6 before 6.0.4 build 93057, VMware Player 2 before 2.0.4 build 93057, and VMware ACE 2 before 2.0.2 build 93057 on Windows allows guest OS users to execute arbitrary code on the host OS via unspecified vectors.

Virtual Machine Communication Interface (VMCI) in VMware Workstation 6.0.x before 6.0.3, VMware Player 2.0.x before 2.0.3, and VMware ACE 2.0.x before 2.0.1 allows attackers to cause a denial of service (host OS crash) via crafted VMCI calls that trigger "memory exhaustion and memory corruption."

VMware Workstation 6.0.x before 6.0.3 and 5.5.x before 5.5.6, VMware Player 2.0.x before 2.0.3 and 1.0.x before 1.0.6, VMware ACE 2.0.x before 2.0.1 and 1.0.x before 1.0.5, and VMware Server 1.0.x before 1.0.5 on Windows allow local users to gain privileges or cause a denial of service by impersonating the authd process through an unspecified use of an "insecurely created named pipe," a different vulnerability than CVE-2008-1361.

Unspecified vulnerability in the DHCP service in VMware Workstation 5.5.x before 5.5.6, VMware Player 1.0.x before 1.0.6, VMware ACE 1.0.x before 1.0.5, VMware Server 1.0.x before 1.0.5, and VMware Fusion 1.1.x before 1.1.1 allows attackers to cause a denial of service.

VMware Workstation 6.0.x before 6.0.3 and 5.5.x before 5.5.6, VMware Player 2.0.x before 2.0.3 and 1.0.x before 1.0.6, VMware ACE 2.0.x before 2.0.1 and 1.0.x before 1.0.5, and VMware Server 1.0.x before 1.0.5 on Windows allow local users to gain privileges via an unspecified manipulation that causes the authd process to connect to an arbitrary named pipe, a different vulnerability than CVE-2008-1362.

Directory traversal vulnerability in the Shared Folders feature for VMWare ACE 1.0.2 and 2.0.2, Player 1.0.4 and 2.0.2, and Workstation 5.5.4 and 6.0.2 allows guest OS users to read and write arbitrary files on the host OS via a multibyte string that produces a wide character string containing .. (dot dot) sequences, which bypasses the protection mechanism, as demonstrated using a "%c0%2e%c0%2e" string.
