CVE-2016-5161

Estado: ModificadaAlta (8.8)—

La función EditingStyle::mergeStyle en WebKit/Source/core/editing/EditingStyle.cpp en Blink, tal como se utiliza en Google Chrome en versiones anteriores a 53.0.2785.89 en Windows y SO X y en versiones anteriores a 53.0.2785.92 en Linux, maneja incorrectamente propiedades del cliente, lo cual permite a atacantes remotos provocar una denegación de servicio o tener otro posible impacto no especificado a través de un sitio web manipulado que aprovecha "tipo de confusión" en la clase StylePropertySerializer.
