Description

Security researcher regenrecht reported via TippingPoint's Zero Day Initiative an error in Mozilla's implementation of NodeIterator in which a malicious NodeFilter could be created which would detach nodes from the DOM tree while it was being traversed. The use of a detached and subsequently deleted node could result in the execution of attacker-controlled memory.
