SUSE CVE-2018-12550

When Eclipse Mosquitto version 1.0 to 1.5.5 inclusive is configured to use an ACL file, and that ACL file is empty, or contains only comments or blank lines, then Mosquitto will treat this as though no ACL file has been defined and use a default allow policy.

The vulnerability of the MQTT v5 broker implementation in the Eclipse Mosquitto protocol allows a attacker to trigger a service failure.

The vulnerability of the MQTT v5 broker implementation in Eclipse Mosquitto lies in excessive loading of the central processor. Exploiting this vulnerability could allow a malicious actor to cause service failures remotely...

CVE-2017-7653

The Eclipse Mosquitto broker up to version 1.4.15 does not reject strings that are not valid UTF-8.
