Updated pnp4nagios package fixes security vulnerabilities:
Cross-site scripting (XSS) vulnerability in share/pnp/application/views/kohana_error_page.php in PNP4Nagios before 0.6.22 allows remote attackers to inject arbitrary web script or HTML via a parameter that is not properly handled in an error message (CVE-2014-4907).
Multiple cross-site scripting (XSS) vulnerabilities in PNP4Nagios through 0.6.22 allow remote attackers to inject arbitrary web script or HTML via the URI used for reaching share/pnp/application/views/kohana_error_page.php or share/pnp/application/views/template.php, leading to improper handling within an http-equiv="refresh" META element (CVE-2014-4908).
