NSS: incorrectly permited skipping of ServerKeyExchange (MFSA 2015-71)
It was found that NSS permitted skipping of the ServerKeyExchange packet during a handshake involving ECDHE Elliptic Curve Diffie-Hellman key Exchange. A remote attacker could use this flaw to bypass the forward-secrecy of a TLS/SSL connection...
