The kernel in Microsoft Windows 2000 SP4, XP SP2 and SP3, Server 2003 SP2, Vista Gold and SP1, and Server 2008 Gold does not properly validate data sent from user mode, which allows local users to gain privileges via a crafted PE .exe file that triggers a NULL pointer dereference during chain traversal, aka "Windows Kernel NULL Pointer Dereference Vulnerability."

Integer underflow in the kernel in Microsoft Windows 2000 SP4, XP SP2 and SP3, Server 2003 SP2, Vista Gold, SP1, and SP2, and Server 2008 Gold and SP2 allows local users to gain privileges via a crafted application that triggers an incorrect truncation of a 64-bit integer to a 32-bit integer, aka "Windows Kernel Integer Underflow Vulnerability."

Double free vulnerability in the kernel in Microsoft Windows 2000 SP4, XP SP2 and SP3, Server 2003 SP1 and SP2, Vista Gold and SP1, and Server 2008 allows local users to gain privileges via a crafted application that makes system calls within multiple threads, aka "Windows Kernel Unhandled Exception Vulnerability." NOTE: according to Microsoft, this is not a duplicate of CVE-2008-4510.

The kernel in Microsoft Windows 2000 SP4, XP SP2 and SP3, Server 2003 SP1 and SP2, Vista Gold and SP1, and Server 2008 does not properly validate window properties sent from a parent window to a child window during creation of a new window, which allows local users to gain privileges via a crafted application, aka "Windows Kernel Window Creation Vulnerability."

Integer overflow in Memory Manager in Microsoft Windows XP SP2 and SP3, Server 2003 SP1 and SP2, Vista Gold and SP1, and Server 2008 allows local users to gain privileges via a crafted application that triggers an erroneous decrement of a variable, related to validation of parameters for Virtual Address Descriptors (VADs) and a "memory allocation mapping error," aka "Virtual Address Descriptor Elevation of Privilege Vulnerability."

Buffer underflow in Microsoft Windows 2000 SP4, XP SP2 and SP3, Server 2003 SP1 and SP2, Vista Gold and SP1, and Server 2008 allows remote attackers to execute arbitrary code via a Server Message Block (SMB) request that contains a filename with a crafted length, aka "SMB Buffer Underflow Vulnerability."
