Description GLSAMaker/CVETool Bot gentoo-dev 2018-04-17 20:22:32 UTC
CVE-2018-0737 (
  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).
