+From db925ae2e65d0d925adef429afc37f75bd1c2017 Mon Sep 17 00:00:00 2001

+Subject: [PATCH] Make DH_check_pub_key() and DH_generate_key() safer yet
+
+We already check for an excessively large P in DH_generate_key(), but not in
+DH_check_pub_key(), and none of them check for an excessively large Q.
+
+This change adds all the missing excessive size checks of P and Q.
+
+It's to be noted that behaviours surrounding excessively sized P and Q
+differ. DH_check() raises an error on the excessively sized P, but only
+sets a flag for the excessively sized Q. This behaviour is mimicked in
+DH_check_pub_key().
