Several local/remote vulnerabilities have been discovered in two of the plugins for the Nagios network monitoring and management system. The Common Vulnerabilities and Exposures project identifies the following problems: . - ------------------------------------------------------------------------Debian Security Advisory DSA-1495-2

Background ========= The Nagios Plugins are an official set of plugins for Nagios, an open source host, service and network monitoring program. Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-analyzer/nagios-plugins < 1.4.10-r1 > = 1.4.10-r1 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: # emerge --sync # emerge -av --oneshot "> =net-analyzer/nagios-plugins-1.4.10-r1" References ========= [ 1 ] CVE-2007-5198 https://www.cve.org/CVERecord?id=CVE-2007-5198 [ 2 ] CVE-2007-5623 https://www.cve.org/CVERecord?id=CVE-2007-5623 Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200711-11 Concerns? ======== Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
