Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2017-3733 high priority: Ubuntu including 2 source packages (openssl, openssl098), 10 status rows across 5 suites (precise, trusty, upstream, xenial, yakkety): not-affected 5, DNE 3, needs-triage 2.
During a renegotiation handshake if the Encrypt-Then-Mac extension is negotiated where it was not in the original handshake (or vice-versa) then this can cause OpenSSL 1.1.0 before 1.1.0e to crash (dependent on ciphersuite). Both clients and servers are affected.
