lib/libssl : tls13_client.c
Log message:
Ensure that a TLSv1.3 server has provided a certificate.
The RFC requires that a server always provide a certificate for
authentication. Ensure that this is the case, rather than proceeding and
attempting validation. In the case where validation was disabled and the
server returned an empty certificate list, this would have previously
resulted in a NULL pointer deference.
