  <affected>
    <package name="net-analyzer/net-snmp" auto="yes" arch="*">
      <unaffected range="ge">5.4.1-r1</unaffected>

  <background>
    <p>
    Net-SNMP is a collection of tools for generating and retrieving SNMP
    data.
    </p>
  </background>
  <description>
    <p>
    The SNMP agent (snmpd) does not properly handle GETBULK requests with
    an overly large "max-repetitions" field.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote unauthenticated attacker could send a specially crafted SNMP
    request to the vulnerable application, possibly resulting in a high CPU
    and memory consumption.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Net-SNMP users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=net-analyzer/net-snmp-5.4.1-r1&quot;</code>
  </resolution>
