Description Josh Bressers 2010-12-06 19:08:56 UTC
Security researcher regenrecht reported via TippingPoint's Zero Day
Initiative that a nsDOMAttribute node can be modified without informing the
iterator object responsible for various DOM traversals. This flaw could
lead to a inconsistent state where the iterator points to an object it
believes is part of the DOM but actually points to some other object. If
such an object had been deleted and its memory reclaimed by the system,
then the iterator could be used to call into attacker-controlled memory.
