| description: | |
| 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. |

| description: | |
| Non-random values for ticket_age_add in session tickets in crypto/tls |
| before Go 1.17.11 and Go 1.18.3 allow an attacker that can observe TLS |
| handshakes to correlate successive connections by comparing ticket ages |
| during session resumption. |
