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.

lsassd in Likewise Open /Enterprise 5.3 before build 7845, Open 6.0 before build 8325, and Enterprise 6.0 before build 178, as distributed in VMware ESXi 4.1 and ESX 4.1 and possibly other products, allows remote attackers to cause a denial of service (daemon crash) via an Active Directory login attempt that provides a username containing an invalid byte sequence.

The extension parser in slp_v2message.c in OpenSLP 1.2.1, and other versions before SVN revision 1647, as used in Service Location Protocol daemon (SLPD) in VMware ESX 4.0 and 4.1 and ESXi 4.0 and 4.1, allows remote attackers to cause a denial of service (infinite loop) via a packet with a "next extension offset" that references this extension or a previous extension. NOTE: some of these details are obtained from third party information.

Cisco Nexus 1000V Virtual Ethernet Module (VEM) 4.0(4) SV1(1) through SV1(3b), as used in VMware ESX 4.0 and 4.1 and ESXi 4.0 and 4.1, does not properly handle dropped packets, which allows guest OS users to cause a denial of service (ESX or ESXi host OS crash) by sending an 802.1Q tagged packet over an access vEthernet port, aka Cisco Bug ID CSCtj17451.

The igb_receive_skb function in drivers/net/igb/igb_main.c in the Intel Gigabit Ethernet (aka igb) subsystem in the Linux kernel before 2.6.34, when Single Root I/O Virtualization (SR-IOV) and promiscuous mode are enabled but no VLANs are registered, allows remote attackers to cause a denial of service (NULL pointer dereference and panic) and possibly have unspecified other impact via a VLAN tagged frame.

Race condition in the sctp_icmp_proto_unreachable function in net/sctp/input.c in Linux kernel 2.6.11-rc2 through 2.6.33 allows remote attackers to cause a denial of service (panic) via an ICMP unreachable message to a socket that is already locked by a user, which causes the socket to be freed and triggers list corruption, related to the sctp_wait_for_connect function.

drivers/scsi/bfa/bfa_core.c in the Linux kernel before 2.6.35 does not initialize a certain port data structure, which allows local users to cause a denial of service (system crash) via read operations on an fc_host statistics file.

The VMware Tools update functionality in VMware Workstation 6.5.x before 6.5.5 build 328052 and 7.x before 7.1.2 build 301548; VMware Player 2.5.x before 2.5.5 build 328052 and 3.1.x before 3.1.2 build 301548; VMware Server 2.0.2; VMware Fusion 2.x before 2.0.8 build 328035 and 3.1.x before 3.1.2 build 332101; VMware ESXi 3.5, 4.0, and 4.1; and VMware ESX 3.0.3, 3.5, 4.0, and 4.1 allows host OS users to gain privileges on the guest OS via unspecified vectors, related to a "command injection" issue.

The xfs implementation in the Linux kernel before 2.6.35 does not look up inode allocation btrees before reading inode buffers, which allows remote authenticated users to read unlinked files, or read or overwrite disk blocks that are currently assigned to an active file but were previously assigned to an unlinked file, by accessing a stale NFS filehandle.
