Title: SMBv2 Negotiation Vulnerability
Description: Array index error in the SMBv2 protocol implementation in srv2.sys in Microsoft Windows Vista Gold, SP1, and SP2, Windows Server 2008 Gold and SP2, and Windows 7 RC allows remote attackers to execute arbitrary code or cause a denial of service (system crash) via an & (ampersand) character in a Process ID High header field in a NEGOTIATE PROTOCOL REQUEST packet, which triggers an attempted dereference of an out-of-bounds memory location, aka "SMBv2 Negotiation Vulnerability." NOTE: some of these details are obtained from third party information.

Microsoft Windows contains a flaw that may allow a malicious user to execute arbitrary code. The issue is triggered when a malicious user sends a specially crafted NEGOTIATE PROTOCOL REQUEST SMBv2 packet with an & (ampersand) character in a Process ID High header field, causing an attempted dereference of an out-of-bounds memory location. It is possible that the flaw may allow arbitrary code execution resulting in a loss of integrity.
