Debian Bug     : 911265 911266 

It was discovered that mosquitto, an MQTT broker, was vulnerable to
remote denial-of-service attacks that could be mounted using various
vectors.

For the stable distribution (stretch), these problems have been fixed in
version 1.4.10-3+deb9u2.

We recommend that you upgrade your mosquitto packages.
