NT Virtual DOS Machine (NTVDM.EXE) in Windows 2000, NT and XP does not verify user execution permissions for 16-bit executable files, which allows local users to bypass the loader and execute arbitrary programs.

Microsoft Windows XP with Fast User Switching (FUS) enabled does not remove the "show processes from all users" privilege when the user is removed from the administrator group, which allows that user to view processes of other users.

Windows File Protection (WFP) in Windows 2000 and XP does not remove old security catalog .CAT files, which could allow local users to replace new files with vulnerable old files that have valid hash codes.

Microsoft Windows XP SP1 allows local users to cause a denial of service (system crash) via an empty datagram to a raw IP over IP socket (IP protocol 4), as originally demonstrated using code in Python 2.3.

The FTP client in Windows XP SP1 and Server 2003, and Internet Explorer 6 SP1 on Windows 2000 SP4, when "Enable Folder View for FTP Sites" is enabled and the user manually initiates a file transfer, allows user-assisted, remote FTP servers to overwrite files in arbitrary locations via crafted filenames.

Remote Desktop in Windows XP SP1 does not verify the "Force shutdown from a remote system" setting, which allows remote attackers to shut down the system by executing TSShutdn.exe.

Buffer overflow in Microsoft Windows 2000, Windows XP SP1 and SP2, and Windows Server 2003 allows local users to cause a denial of service (i.e., system crash) via a malformed request, aka "Object Management Vulnerability".

Sign extension vulnerability in the createBrushIndirect function in the GDI library (gdi32.dll) in Microsoft Windows XP, Server 2003, and possibly other versions, allows user-assisted attackers to cause a denial of service (application crash) via a crafted WMF file.
