VMware Workstation 8.x before 8.0.4, VMware Player 4.x before 4.0.4, VMware ESXi 3.5 through 5.0, and VMware ESX 3.5 through 4.1 allow remote attackers to cause a denial of service (guest OS crash) via crafted traffic from a remote virtual device.

VMware ESXi 3.5 through 5.0 and ESX 3.5 through 4.1 allow remote attackers to execute arbitrary code or cause a denial of service (memory overwrite) via NFS traffic.

If igb's SR-IOV and promiscuous mode are enabled and the interface receives a tag VLAN packet, this will result in a null pointer dereference. To fix this, we will backport upstream commit 31b24b95 to ensure that vlangroreceive is only used if vlans have been registered to the adapter structure.

[ This fixes bugzilla entry 15582 -Eric Dumazet]

It matters if CONFIGPCIIOV is enabled, e.g. grep -ir SRIOV drivers/net/igb/.
