Description
Microsoft Windows Vista Gold, SP1, and SP2, Windows Server 2008 Gold and SP2, and Windows 7 RC do not properly process the command value in an SMB Multi-Protocol Negotiate Request packet, which allows remote attackers to execute arbitrary code via a crafted SMBv2 packet to the Server service, aka "SMBv2 Command Value Vulnerability."
