CVE-2015-7207

Estado: ModificadaMedia (5)—

Mozilla Firefox en versiones anteriores a 43.0 no restringe adecuadamente la disponibilidad de los tiempos de la API Timing IFRAME Resource, lo que permite a atacantes remotos eludir la Same Origin Policy y obtener información sensible a través de código JavaScript manipulado que aprovecha las llamadas history.back y performance.getEntries, un problema relacionado con CVE-2015-1300.
