CVE-2017-3733: Encrypt-Then-Mac renegotiation crash
First published: Thu May 04 2017(Updated: )
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.
