-From 193c16a3648b8670a762e925b6ac6e074f468a20 Mon Sep 17 00:00:00 2001
-From: Filippo Valsorda <filippo@golang.org>

-Subject: [PATCH] crypto/elliptic: reduce subtraction term to prevent long busy loop
-
-If beta8 is unusually large, the addition loop might take a very long
-time to bring x3-beta8 back positive.
-
-This would lead to a DoS vulnerability in the implementation of the
-P-521 and P-384 elliptic curves that may let an attacker craft inputs
-to ScalarMult that consume excessive amounts of CPU.
-
-This fixes CVE-2019-6486.
-
-Fixes #29903
