How to fix?

NVD Description

Note: Versions mentioned in the description apply only to the upstream openssl1.0 package and not the openssl1.0 package as distributed by Ubuntu. See How to fix? for Ubuntu:18.04 relevant fixed versions and status.

Libgcrypt before 1.7.10 and 1.8.x before 1.8.3 allows a memory-cache side-channel attack on ECDSA signatures that can be mitigated through the use of blinding during the signing process in the _gcry_ecc_ecdsa_sign function in cipher/ecc-ecdsa.c, aka the Return Of the Hidden Number Problem or ROHNP. To discover an ECDSA key, the attacker needs access to either the local machine or a different virtual machine on the same physical host.
