The OpenSSL RSA Key generation algorithm has been shown to be vulnerable to
a cache timing side channel attack. An attacker with sufficient access to
mount cache timing attacks during the RSA key generation process could
recover the private key. Fixed in OpenSSL 1.1.0i-dev (Affected
1.1.0-1.1.0h). Fixed in OpenSSL 1.0.2p-dev (Affected 1.0.2b-1.0.2o).
