  <synopsis>

  <affected>
    <package name="dev-perl/Net-DNS" auto="yes" arch="*">
      <unaffected range="ge">0.60</unaffected>

  <background>
    <p>
    Net::DNS is a Perl implementation of a DNS resolver.
    </p>
  </background>
  <description>
    <p>
    hjp discovered an error when handling DNS query IDs which make them
    partially predictable. Steffen Ullrich discovered an error in the
    dn_expand() function which could lead to an endless loop.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could send a specially crafted DNS request to the
    server which could result in a Denial of Service with an infinite
    recursion, or perform a cache poisoning attack.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Net::DNS users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=dev-perl/Net-DNS-0.60"</code>
  </resolution>
