Descriptions

Mozilla Firefox before 42.0 and Firefox ESR 38.x before 38.4 improperly control the ability of a web worker to create a WebSocket object, which allows remote attackers to bypass intended mixed-content restrictions via crafted JavaScript code.

Mozilla Firefox en versiones anteriores a 42.0 y Firefox ESR 38.x en versiones anteriores a 38.4 controla indebidamente la capacidad de un web worker para crear un objeto WebSocket, lo que permite a atacantes remotos eludir las restricciones destinadas al contenido mixto a través de código JavaScript manipulado.
