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.

Notes

Author Note
mdeslaur only affects 1.1.x
