<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).

</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>
