  <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>

  <description>
    <p>Multiple vulnerabilities have been discovered in OpenSSL. Please review
      the CVE identifiers referenced below for details.
    </p>
  </description>
  <impact type="normal">
    <p>A remote attacker to obtain sensitive information, caused by the failure
      to immediately close the TCP connection after the hosts encounter a
      zero-length record with valid padding.
    </p>
    
    <p>A local attacker could run a malicious process next to legitimate
      processes using the architecture’s parallel thread running capabilities
      to leak encrypted data from the CPU’s internal processes.
    </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-1.0.2r"
    </code>
