Description Josh Bressers 2010-09-03 12:05:07 EDT
Mozilla developer Blake Kaplan reported that the wrapper class
XPCSafeJSObjectWrapper (SJOW), a security wrapper that allows

scope chains ending in outer objects. Users of SJOWs which expect the scope
chain to end on an inner object may be handed a chrome privileged object
which could be leveraged to run arbitrary JavaScript with chrome
