We apologize for the inconvenience.

Original advisory details:

 It was discovered that Nagios incorrectly handled certain long strings. A
 remote authenticated attacker could use this issue to cause Nagios to
 crash, resulting in a denial of service, or possibly obtain sensitive
 information. (CVE-2013-7108, CVE-2013-7205)

 It was discovered that Nagios incorrectly handled certain long messages to
 cmd.cgi. A remote attacker could possibly use this issue to cause Nagios to
 crash, resulting in a denial of service. (CVE-2014-1878)

 Dawid Golunski discovered that Nagios incorrectly handled symlinks when
 accessing log files. A local attacker could possibly use this issue to
 elevate privileges. In the default installation of Ubuntu, this should be
 prevented by the Yama link restrictions. (CVE-2016-9566)");
