Security researcher Orlando Barrera II of SecTheory reported, via TippingPoint’s Zero Day Initiative, that Mozilla’s implementation of Web Workers contained an error in its handling of array data types when processing posted messages. This error could be used by an attacker to corrupt heap memory and crash the browser, potentially running arbitrary code on a victim’s computer.
