The DHTML Edit Control (dhtmled.ocx) allows remote attackers to inject arbitrary web script into other domains by setting a name for a window, opening a child page whose target is the window with the given name, then injecting the script from the parent into the child using execScript, as demonstrated by "AbusiveParent" in Internet Explorer 6.0.2900.2180.

Internet Explorer in Windows XP SP2, and other versions including 5.01 and 5.5, allows remote attackers to install arbitrary programs via a web page that uses certain styles and the AnchorClick behavior, popup windows, and drag-and-drop capabilities to drop the program in the local startup folder, as demonstrated by "wottapoop.html".
