  <description>
    <p>Multiple heap and stack overflows and double free vulnerabilities have
      been discovered in GnuTLS by the OSS-Fuzz project. Please review the CVE
      identifiers referenced below for details.
    </p>
  </description>
  <impact type="normal">
    <p>A remote attacker could entice a user or automated system to process a
      specially crafted certificate using an application linked against GnuTLS.
      This could possibly result in the execution of arbitrary code with the
      privileges of the process or a Denial of Service condition.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All GnuTLS users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=net-libs/gnutls-3.3.26"
    </code>
