How to fix?

There is no fixed version for Mosquitto.

Overview

Mosquitto is an open source implementation of a server for version 3.1 and 3.1.1 of the MQTT protocol.

Affected versions of this package are vulnerable to Improper Access Control. Mosquitto is vulnerable to potentially insecure configuration issues. The vulnerability is caused by a SIGHUP signal when no additional file descriptors can be allocated by the broker when opening the configuration file. This causes the default configuration values to be reloaded, which can potentially strip off the intended security options.
