  <background>
    <p>BIND is the Berkeley Internet Name Domain Server.</p>
  </background>
  <description>
    <p>Multiple vulnerabilities have been discovered in BIND:</p>
    
    <ul>
      <li>Domain names are not properly revoked due to an error in the cache
        update policy (CVE-2012-1033).
      </li>
      <li>BIND accepts records with zero-length RDATA fields (CVE-2012-1667).</li>
      <li>An assertion failure from the failing-query cache could occur when
        DNSSEC validation is enabled (CVE-2012-3817).
      </li>
      <li>A memory leak may occur under high TCP query loads (CVE-2012-3868).</li>
      <li>An assertion error can occur when a query is performed for a record
        with RDATA greater than 65535 bytes (CVE-2012-4244).
      </li>
    </ul>
  </description>
  <impact type="normal">
    <p>A remote attacker may be able to cause a Denial of Service condition or
      keep domain names resolvable after it has been deleted from registration.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All BIND users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=net-dns/bind-9.9.1_p3"
    </code>
