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/.

Buffer overflow in OpenPegasus Management server, when compiled to use PAM and with PEGASUSUSEPAMSTANDALONEPROC defined, as used in VMWare ESX Server 3.0.1 and 3.0.2, might allow remote attackers to execute arbitrary code via vectors related to PAM authentication, a different vulnerability than CVE-2008-0003.
