OpenBSD 6.3 errata 022 MFC: Avoid a timing side-channel leak when generating DSA and ECDSA 2018-06-13T15:08:08+00:00 jsing 2018-06-13T15:08:08+00:00 urn:sha1:752cb6f550d07071e7ee95a9266cb5f555f57ee6 signatures. This is caused by an attempt to do fast modular arithmetic, which introduces branches that leak information regarding secret values.
