has the ability to send email or page alerts when a problem arises or is
resolved.

Security Fix(es):

could be used to gain access to the remote system and in some scenarios
control over the system. (CVE-2016-9565)

* A privilege escalation flaw was found in the way Nagios handled log
files. An attacker able to control the Nagios logging configuration (the
