    <p>OpenSSL is an Open Source toolkit implementing the Secure Sockets Layer
      (SSL v2/v3) and Transport Layer Security (TLS v1/v1.1/v1.2/v1.3) 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 could perform a malicious crafted TLS 1.3 handshake
      against an application using OpenSSL, possibly resulting in a Denial of
      Service condition.
    </p>
    
    <p>In addition, it’s feasible that an attacker might attack DH512.</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-1.1.1g"
    </code>
