CVE-2015-0800

Estado: ModificadaMedia (5)—

La implementación PRNG en el solucionador (resolver) DNS en Mozilla Firefox (también conocido como Fennec) anterior a 37.0 en Android no genera correctamente números aleatorios para los valores de identificadores de consultas y los puertos de fuentes UDP, lo que facilita a atacantes remotos falsificar las respuestas DNS mediante la adivinación de estos números, un problema relacionado con CVE-2012-2808.
