Description Vincent Danen 2012-01-31 20:46:32 UTC

It was found that removed child nodes of nsDOMAttribute could be accessed under certain circumstances, due to premature notification of AttributeChildRemoved.  This use-after-free of the child nodes could possibly allow for the the remote execution of arbitrary code.
