- An error exists related to the implementation of the
    Elliptic Curve Digital Signature Algorithm (ECDSA) that
    could allow nonce disclosure via the 'FLUSH+RELOAD'
    cache side-channel attack. (CVE-2014-0076)

  - An unspecified error exists that could allow an
    attacker to cause usage of weak keying material
    leading to simplified man-in-the-middle attacks.
    (CVE-2014-0224)

  - An unspecified error exists related to anonymous ECDH
    ciphersuites that could allow denial of service
    attacks. Note this issue only affects OpenSSL TLS
    clients. (CVE-2014-3470)");
