Description
Security researcher regenrecht reported via TippingPoint's Zero Day Initiative that removed child nodes of nsDOMAttribute can be accessed under certain circumstances because of a premature notification of AttributeChildRemoved. This use-after-free of the child nodes could possibly allow for remote code execution.
