    Domain Name System (DNS) protocol.

  <description>
    <p>
    Multiple cache poisoning vulnerabilities were discovered in BIND. For
    further information please consult the CVE entries and the ISC Security
    Bulletin referenced below.
    </p>
    <p>
    Note: CVE-2010-0290 and CVE-2010-0382 exist because of an incomplete
    fix and a regression for CVE-2009-4022.
    </p>
  </description>
  <impact type="normal">
    <p>
    An attacker could exploit this weakness to poison the cache of a
    recursive resolver and thus spoof DNS traffic, which could e.g. lead to
    the redirection of web or mail traffic to malicious sites.
    </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-9.4.3_p5"</code>
  </resolution>
