The OpenSSL project reports:
Severity: High
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 to
crash (dependent on ciphersuite). Both clients and servers
are affected.
This issue does not affect OpenSSL version 1.0.2.
