Synopsis |
| 19 |
======== |
| 20 |
|
| 21 |
Two buffer overflow vulnerabilities in the Nagios Plugins might allow |
| 22 |
for remote execution of arbitrary code. |
| 23 |
|
| 24 |
Background |
| 25 |
========== |
| 26 |
|
| 27 |
The Nagios Plugins are an official set of plugins for Nagios, an open |
| 28 |
source host, service and network monitoring program. |
| 29 |
|
| 30 |
Affected packages |
| 31 |
================= |
| 32 |
|

------------------------------------------------------------------- |
| 34 |
Package / Vulnerable / Unaffected |
| 35 |

| 36 |

|

Description |
| 39 |
=========== |
| 40 |
|
| 41 |
fabiodds reported a boundary checking error in the "check_snmp" plugin |
| 42 |
when processing SNMP "GET" replies that could lead to a stack-based |
| 43 |
buffer overflow (CVE-2007-5623). Nobuhiro Ban reported a boundary |
| 44 |
checking error in the redir() function of the "check_http" plugin when |
| 45 |
processing HTTP "Location:" header information which might lead to a |
| 46 |
buffer overflow (CVE-2007-5198). |
| 47 |
|
| 48 |
Impact |
| 49 |
====== |
| 50 |
|
| 51 |
A remote attacker could exploit these vulnerabilities to execute |
| 52 |
arbitrary code with the privileges of the user running Nagios or cause |
| 53 |
a Denial of Service by (1) sending a specially crafted SNMP "GET" reply |
| 54 |
to the Nagios daemon or (2) sending an overly long string in the |
| 55 |
"Location:" header of an HTTP reply. Note that to exploit (2), the |
| 56 |
malicious or compromised web server has to be configured in Nagios and |
| 57 |
the "-f" (follow) option has to be enabled. |
| 58 |
|
| 59 |
Workaround |
| 60 |
========== |
| 61 |
|
| 62 |
There is no known workaround at this time. |
| 63 |
|
| 64 |
Resolution |
| 65 |
========== |
| 66 |
|
| 67 |
All users of the Nagios Plugins should upgrade to the latest version: |
| 68 |
|
| 69 |
# emerge --sync |
| 70 |
# emerge -av --oneshot ">=net-analyzer/nagios-plugins-1.4.10-r1" |
| 71 |
|
