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.

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.

Integer overflow in the ISC dhcpd 3.0.x before 3.0.7 and 3.1.x before 3.1.1; and the DHCP server in EMC VMware Workstation before 5.5.5 Build 56455 and 6.x before 6.0.1 Build 55017, Player before 1.0.5 Build 56455 and Player 2 before 2.0.1 Build 55017, ACE before 1.0.3 Build 54075 and ACE 2 before 2.0.1 Build 55017, and Server before 1.0.4 Build 56528; allows remote attackers to cause a denial of service (daemon crash) or execute arbitrary code via a malformed DHCP packet with a large dhcp-max-message-size that triggers a stack-based buffer overflow, related to servers configured to send many DHCP options to clients.

The PIIX4 power management subsystem in EMC VMware Workstation 5.5.3.34685 and VMware Server 1.0.1.29996 allows local users to write to arbitrary memory locations via a crafted poke to I/O port 0x1004, triggering a denial of service (virtual machine crash) or other unspecified impact, a related issue to CVE-2007-1337.

VMware Workstation 5.5.3 build 34685 does not provide per-user restrictions on certain privileged actions, which allows local users to perform restricted operations such as changing system time, accessing hardware components, and stopping the "VMware tools service" service. NOTE: exploitation is simplified via (1) weak file permissions (Users = Read & Execute) for %PROGRAMFILES%\VMware; and weak registry key permissions (access by Users) for (2) vmmouse, (3) vmscsi, (4) VMTools, (5) vmx_svga, and (6) vmxnet in HKLM\SYSTEM\CurrentControlSet\Services\; which allows local users to perform various privileged actions outside of the guest OS by executing certain files under %PROGRAMFILES%\VMware\VMware Tools, as demonstrated by (a) VMControlPanel.cpl and (b) vmwareservice.exe.
