Description of the vulnerability

OpenSSL implements the possibility of renegotiation of TLS option and parameters during a session.

However, for some combinations of algorithms, the negation of the state of the option "Encrypt-Then-Mac" generates a fatal error.

An attacker can therefore change the state of the "Encrypt-Then-Mac" TLS option in a renegotiation with a server or client based on OpenSSL, in order to trigger a denial of service.
