VMware ESXi 3.5, 4.0, and 4.1 and ESX 3.5, 4.0, and 4.1 do not properly implement port-based I/O operations, which allows guest OS users to gain guest OS privileges by overwriting memory locations in a read-only memory block associated with the Virtual DOS Machine.

Buffer overflow in the WDDM display driver in VMware ESXi 4.0, 4.1, and 5.0; VMware ESX 4.0 and 4.1; and VMware View before 4.6.1 allows guest OS users to gain guest OS privileges via unspecified vectors.

The XPDM display driver in VMware ESXi 4.0, 4.1, and 5.0; VMware ESX 4.0 and 4.1; and VMware View before 4.6.1 allows guest OS users to gain guest OS privileges or cause a denial of service (NULL pointer dereference) via unspecified vectors.

net/core/ethtool.c in the Linux kernel before 2.6.36 does not initialize certain data structures, which allows local users to obtain potentially sensitive information from kernel heap memory by leveraging the CAP_NET_ADMIN capability for an ethtool ioctl call.

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.

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, when a Solaris or FreeBSD guest OS is used, allows guest OS users to modify arbitrary guest OS files via unspecified vectors, related to a "procedural error."

Race condition in 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 gain privileges on the guest OS by mounting a filesystem on top of an arbitrary directory.

The socket implementation in net/core/sock.c in the Linux kernel before 2.6.34 does not properly manage a backlog of received packets, which allows remote attackers to cause a denial of service (memory consumption) by sending a large amount of network traffic, as demonstrated by netperf UDP tests.

The self-extracting installer in the vSphere Client Installer package in VMware vCenter 4.0 before Update 3 and 4.1 before Update 1, VMware ESXi 4.x before 4.1 Update 1, and VMware ESX 4.x before 4.1 Update 1 does not have a digital signature, which might make it easier for remote attackers to spoof the software distribution via a Trojan horse installer.

VMware ESXi 4.0 and 4.1 and ESX 4.0 and 4.1 allow remote attackers to cause a denial of service (socket exhaustion) via unspecified network traffic.
