+From c394a488942387246653833359a5c94b5832674e Mon Sep 17 00:00:00 2001
+From: "Dr. Stephen Henson" <steve@openssl.org>
+Date: Fri, 2 Oct 2015 12:35:19 +0100
+Subject: [PATCH] Add PSS parameter check.
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+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.
