  <background>
    <p>OpenSSL is an Open Source toolkit implementing the Secure Sockets Layer
      (SSL v2/v3) and Transport Layer Security (TLS v1) as well as a general
      purpose cryptography library.
    </p>
  </background>
  <description>
    <p>Multiple vulnerabilities have been discovered in OpenSSL. Please review
      the upstream advisory and CVE identifiers referenced below for details.
      Note that the list includes CVE identifiers for an older OpenSSL Security
      Advisory (3 Dec 2015) for which we have not issued a GLSA before.
    </p>
  </description>
  <impact type="normal">
    <p>A remote attacker could disclose a server’s private DH exponent, or
      complete SSLv2 handshakes using ciphers that have been disabled on the
      server.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All OpenSSL users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=dev-libs/openssl-1.0.2f"
    </code>
