Security researcher Paul Stone reported that a
browser applet could be used to turn a simple mouse click into a
drag-and-drop action, potentially resulting in the unintended loading
of resources in a user's browser. This behavior could be used twice
in succession to first load a privileged chrome: URL in a
victim's browser, then load a malicious javascript: URL
on top of the same document resulting in arbitrary script execution
with chrome privileges.
