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).
