OpenSSL -- Multiple vulnerabilities in 1.1 branch

The OpenSSL project reports:

Timing vulnerability in ECDSA signature generation
(CVE-2018-0735): The OpenSSL ECDSA signature algorithm has been
shown to be vulnerable to a timing side channel attack. An
attacker could use variations in the signing algorithm to
recover the private key (Low).
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 (Low).
