Name of the Vulnerable Software and Affected Versions Icinga 2 versions 2.10.0 through 2.15.0 Icinga 2 version 2.13.12 and earlier Icinga 2 version 2.14.6 and earlier

Description Icinga 2, an open source monitoring system, is susceptible to a denial-of-service condition. Creating an invalid reference, such as a reference to null, can lead to a segmentation fault. This can be triggered by any API user with access to an API endpoint that allows specifying a filter expression, causing the Icinga 2 daemon to crash. The issue occurs when dereferencing the invalid reference.

Recommendations Update to Icinga 2 version 2.15.1 or later. Update to Icinga 2 version 2.14.7 or later. Update to Icinga 2 version 2.13.13 or later.
