The Internet Authentication Service (IAS) in Microsoft Windows Vista SP2 and Server 2008 SP2 does not properly validate MS-CHAP v2 Protected Extensible Authentication Protocol (PEAP) authentication requests, which allows remote attackers to execute arbitrary code via crafted structures in a malformed request, aka "Internet Authentication Service Memory Corruption Vulnerability."

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."

The kernel in Microsoft Windows 2000 SP4, XP SP2 and SP3, Server 2003 SP2, Vista Gold, SP1, and SP2, and Server 2008 SP2 does not properly validate user-mode pointers in unspecified error conditions, which allows local users to gain privileges via a crafted application, aka "Windows Kernel Pointer Validation Vulnerability."

The kernel in Microsoft Windows 2000 SP4, XP SP2 and SP3, Server 2003 SP2, Vista Gold, SP1, and SP2, and Server 2008 SP2 does not properly validate an argument to an unspecified system call, which allows local users to gain privileges via a crafted application, aka "Windows Driver Class Registration Vulnerability."

The kernel in Microsoft Windows 2000 SP4, XP SP2 and SP3, and Server 2003 SP2 does not properly validate the user-mode input associated with the editing of an unspecified desktop parameter, which allows local users to gain privileges via a crafted application, aka "Windows Desktop Parameter Edit Vulnerability."
