CVE-2016-1643

Estado: ModificadaAlta (8.8)—

La función ImageInputType::ensurePrimaryContent en WebKit/Source/core/html/forms/ImageInputType.cpp en Blink, como se utiliza en Google Chrome en versiones anteriores a 49.0.2623.87, no mantiene adecuadamente el user agent shadow DOM, lo que permite a atacantes remotos causar una denegación de servicio o posiblemente tener otro impacto no especificado a través de vectores que aprovechan "type confusion".
