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 ticketageadd, which allows an attacker that can observe TLS handshakes to correlate successive connections by comparing ticket ages during session resumption.
