Description Josh Bressers 2010-09-03 16:05:07 UTC
Mozilla developer Blake Kaplan reported that the wrapper class
XPCSafeJSObjectWrapper (SJOW), a security wrapper that allows
content-defined objects to be safely accessed by privileged code, creates
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
privileges.
