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).

<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.
|
|

|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.

</workaround>

|
<resolution>
|
|
<p>
|
|
All users of the Nagios Plugins should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-analyzer/nagios-plugins-1.4.10-r1"</code>
