Descriptions
Mozilla Network Security Services (NSS) before 3.20.2, as used in Mozilla Firefox before 43.0.2 and Firefox ESR 38.x before 38.5.2, does not reject MD5 signatures in Server Key Exchange messages in TLS 1.2 Handshake Protocol traffic, which makes it easier for man-in-the-middle attackers to spoof servers by triggering a collision.
Mozilla Network Security Services (NSS) en versiones anteriores a 3.20.2, tal como se utiliza en Mozilla Firefox en versiones anteriores a 43.0.2 y Firefox ESR 38.x en versiones anteriores a 38.5.2, no rechaza las firmas MD5 en mensajes Server Key Exchange en el tráfico de TLS 1.2 Handshake Protocol, lo que facilita a atacantes man-in-the-middle falsificar servidores desencadenando una colisión.
A flaw was found in the way TLS 1.2 could use the MD5 hash function for signing ServerKeyExchange and Client Authentication packets during a TLS handshake. A man-in-the-middle attacker able to force a TLS connection to use the MD5 hash function could use this flaw to conduct collision attacks to impersonate a TLS server or an authenticated TLS client.
