XMLHTTP control in Microsoft XML Core Services 2.6 and later does not properly handle IE Security Zone settings, which allows remote attackers to read arbitrary files by specifying a local file as an XML Data Source.
Win32k.sys (aka Graphics Device Interface (GDI)) in Windows 2000 and XP allows local users to cause a denial of service (system crash) by calling the ShowWindow function after receiving a WM_NCCREATE message.
Windows XP with fast user switching and account lockout enabled allows local users to deny user account access by setting the fast user switch to the same user (self) multiple times, which causes other accounts to be locked out.
The Remote Desktop client in Windows XP sends the most recent user account name in cleartext, which could allow remote attackers to obtain terminal server user account names via sniffing.
Buffer overflow in Universal Plug and Play (UPnP) on Windows 98, 98SE, ME, and XP allows remote attackers to execute arbitrary code via a NOTIFY directive with a long Location URL.
Universal Plug and Play (UPnP) on Windows 98, 98SE, ME, and XP allows remote attackers to cause a denial of service via (1) a spoofed SSDP advertisement that causes the client to connect to a service on another machine that generates a large amount of traffic (e.g., chargen), or (2) via a spoofed SSDP announcement to broadcast or multicast addresses, which could cause all UPnP clients to send traffic to a single target system.
Universal Plug and Play (UPnP) in Windows 98, 98SE, ME, and XP allows remote attackers to cause a denial of service (memory consumption or crash) via a malformed UPnP request.
Terminal Services Manager MMC in Windows 2000 and XP trusts the Client Address (IP address) that is provided by the client instead of obtaining it from the packet headers, which allows clients to spoof their public IP address, e.g. through a Network Address Translation (NAT).
