  - CVE-2018-0732: A flaw in the bundled third-party component OpenSSL library's key handling during
  a TLS handshake that causes a denial of service vulnerability.

  - CVE-2018-0734: A flaw in the bundled third-party component OpenSSL library's DSA signature
  algorithm that renders it vulnerable to a timing side channel attack. An attacker could leverage
  this vulnerability to recover the private key.

  - CVE-2018-0737: A flaw in the bundled third-party component OpenSSL library's RSA Key generation
  algorithm that allows a cache timing side channel attack to recover the private key.

  - CVE-2018-5407: A flaw in the bundled third-party component OpenSSL library's Simultaneous
  Multithreading (SMT) architectures which render it vulnerable to side-channel leakage. This issue
  is known as 'PortSmash'. An attacker could possibly use this issue to perform a timing side-channel
  attack and recover private keys.");
