+Subject: [PATCH] DH_check(): Do not try checking q properties if it is
+ obviously invalid
+
+If  |q| >= |p| then the q value is obviously wrong as q
+is supposed to be a prime divisor of p-1.
+
+We check if p is overly large so this added test implies that
+q is not large either when performing subsequent tests using that
+q value.
+
+Otherwise if it is too large these additional checks of the q value
+such as the primality test can then trigger DoS by doing overly long
+computations.
