openssl: Malicious server can send large prime to client during DH(E) TLS handshake causing the client to hang

During key agreement in a TLS handshake using a DHE based ciphersuite a malicious server can send a very large prime value to the client. This will cause the client to spend an unreasonably long period of time generating a key for this prime resulting in a hang until the client has finished. This...
