Descriptions
The HTTP Alternative Services feature in Mozilla Firefox before 37.0.1 allows man-in-the-middle attackers to bypass an intended X.509 certificate-verification step for an SSL server by specifying that server in the uri-host field of an Alt-Svc HTTP/2 response header.
La característica HTTP Alternative Services en Mozilla Firefox anterior a 37.0.1 permite a atacantes man-in-the-middle evadir la verificación de los certificados X.509 para un servidor SSL mediante la especificación de este servidor en el campo uri-host de una cabecera de respuesta Alt-Svc HTTP/2.
Muneaki Nishimura discovered a flaw in Mozilla's HTTP Alternative Services implementation which meant SSL certificate verification could be bypassed in some circumstances. A remote attacker could potentially exploit this to conduct a man in the middle attack.
