openssl: OpenSSL TLS 1.3 server may choose unexpected key agreement group

A key group selection preference flaw has been discovered in OpenSSL. An OpenSSL TLS 1.3 server may fail to negotiate the expected preferred key exchange group when its key exchange group configuration includes the default by using the "DEFAULT" keyword. A less preferred key exchange may be used...
