Multiple cross-site scripting (XSS) vulnerabilities in CGI programs in Nagios before 2.12 might allow remote attackers to inject arbitrary web script or HTML via unspecified vectors, a different issue than CVE-2007-5624 and CVE-2008-1360.

Cross-site scripting (XSS) vulnerability in Nagios before 2.11 allows remote attackers to inject arbitrary web script or HTML via unknown vectors to unspecified CGI scripts, a different issue than CVE-2007-5624.

Buffer overflow in the check_snmp function in Nagios Plugins (nagios-plugins) 1.4.10 allows remote attackers to cause a denial of service (crash) via crafted snmpget replies.

Cross-site scripting (XSS) vulnerability in Nagios 2.x before 2.10 allows remote attackers to inject arbitrary web script or HTML via unknown vectors to unspecified CGI scripts.

Buffer overflow in the redir function in check_http.c in Nagios Plugins before 1.4.10, when running with the -f (follow) option, allows remote web servers to execute arbitrary code via Location header responses (redirects) with a large number of leading "L" characters.

Integer overflow in CGI scripts in Nagios 1.x before 1.4.1 and 2.x before 2.3.1 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a content length (Content-Length) HTTP header. NOTE: this is a different vulnerability than CVE-2006-2162.

Buffer overflow in CGI scripts in Nagios 1.x before 1.4 and 2.x before 2.3 allows remote attackers to execute arbitrary code via a negative content length (Content-Length) HTTP header.

Nagios 1.0b1 through 1.0b3 allows remote attackers to execute arbitrary commands via shell metacharacters in plugin output.
