    <p>
    The Nagios Plugins are an official set of plugins for Nagios, an open
    source host, service and network monitoring program.

  <description>
    <p>
    fabiodds reported a boundary checking error in the "check_snmp" plugin
    when processing SNMP "GET" replies that could lead to a stack-based
    buffer overflow (CVE-2007-5623). Nobuhiro Ban reported a boundary
    checking error in the redir() function of the "check_http" plugin when
    processing HTTP "Location:" header information which might lead to a
    buffer overflow (CVE-2007-5198).
    </p>
  </description>
  <impact type="high">
    <p>
    A remote attacker could exploit these vulnerabilities to execute
    arbitrary code with the privileges of the user running Nagios or cause
    a Denial of Service by (1) sending a specially crafted SNMP "GET" reply
    to the Nagios daemon or (2) sending an overly long string in the
    "Location:" header of an HTTP reply. Note that to exploit (2), the
    malicious or compromised web server has to be configured in Nagios and
    the "-f" (follow) option has to be enabled.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All users of the Nagios Plugins should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=net-analyzer/nagios-plugins-1.4.10-r1&quot;</code>
  </resolution>
