+Subject:Add PSS parameter check.
+
+Avoid seg fault by checking mgf1 parameter is not NULL. This can be
+triggered during certificate verification so could be a DoS attack
+against a client or a server enabling client authentication.
+
+Thanks to Loïc Jonas Etienne (Qnective AG) for discovering this bug.
