    netsnmp_create_subtree_cache() function in agent/snmp_agent.c when
    processing GETBULK requests.

  <impact type="normal">
    <p>
    A remote attacker could send a specially crafted request to crash the
    SNMP server. NOTE: The attacker needs to know the community string to
    exploit this vulnerability.
    </p>
  </impact>
  <workaround>
    <p>
    Restrict access to trusted entities only.
    </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-5.4.2.1&quot;</code>
  </resolution>
