Gentoo Linux Security Advisory

Title: Nagios Plugins: Two buffer overflows (GLSA 200711-11)
Severity: high
Exploitable: remote
Date: November 08, 2007
Bug(s): #196308, #194178
ID: 200711-11

Synopsis

Two buffer overflow vulnerabilities in the Nagios Plugins might allow for remote execution of arbitrary code.

Background

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

Affected Packages

Package: net-analyzer/nagios-plugins
Vulnerable: < 1.4.10-r1
Unaffected: >= 1.4.10-r1
Architectures: All supported architectures


Description

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

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

There is no known workaround at this time.

Resolution

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