Descriptions

Mozilla Firefox before 47.0 and Firefox ESR 45.x before 45.2 do not ensure that the user approves the fullscreen and pointerlock settings, which allows remote attackers to cause a denial of service (UI outage), or conduct clickjacking or spoofing attacks, via a crafted web site.

Mozilla Firefox en versiones anteriores a 47.0 y Firefox ESR 45.x en versiones anteriores a 45.2 no asegura que el usuario apruebe los ajustes de pantalla completa y pointerlock, lo que permite a atacantes remotos provocar una denegación de servicio (interrupción de UI), o llevar a cabo ataques de clickjacking o de suplantación, a través de un sitio web manipulado.
