Mozilla security researcher moz_bug_r_a4 reported that the owner document of an element can become null after garbage collection. In such cases, event listeners may be executed within the wrong JavaScript context. An attacker could potentially use this vulnerability to have a malicious event handler execute arbitrary JavaScript with chrome privileges.
