Security Fix(es):
* openssl: timing side channel attack in the DSA signature algorithm
(CVE-2018-0734)
* openssl: timing side channel attack in the ECDSA signature generation
(CVE-2018-0735)
* openssl: ChaCha20-Poly1305 with long nonces (CVE-2019-1543)
For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE
page(s) listed in the References section.
Additional Changes:

1644364 - CVE-2018-0734 openssl: timing side channel attack in the DSA signature algorithm
1668880 - ec man page lists -modulus but the tool doesn't support it
1686058 - specifying digest for signing time-stamping responses is mandatory
1686548 - Incorrect handling of fragmented KeyUpdate messages
1695954 - CVE-2019-1543 openssl: ChaCha20-Poly1305 with long nonces
1697915 - Race/segmentation fault on process shutdown in OpenSSL
1706104 - openssl asn1parse crashes with double free or corruption (!prev)
1706915 - OpenSSL should implement continuous random test or use the kernel AF_ALG interface for random
