    Summary: Session tickets lack random ticket_age_add in crypto/tls

    Details: An attacker can correlate a resumed TLS session with a previous connection. Session tickets generated by crypto/tls do not contain a randomly generated ticket_age_add, which allows an attacker that can observe TLS handshakes to correlate successive connections by comparing ticket ages during session resumption.
