-Subject: [PATCH] Timing vulnerability in DSA signature generation
- (CVE-2018-0734).
-
-Avoid a timing attack that leaks information via a side channel that
-triggers when a BN is resized.  Increasing the size of the BNs
-prior to doing anything with them suppresses the attack.
-
-Thanks due to Samuel Weiser for finding and locating this.

-(cherry picked from commit a9cfb8c2aa7254a4aa6a1716909e3f8cb78049b6)
