Description

The Eclipse Mosquitto broker up to version 1.4.15 does not reject strings that are not valid UTF-8. A malicious client could cause other clients that do reject invalid UTF-8 strings to disconnect themselves from the broker by sending a topic string which is not valid UTF-8, and so cause a denial of service for the clients.

Solution(s)

  • ubuntu-upgrade-libmosquitto1
  • ubuntu-upgrade-libmosquittopp1
  • ubuntu-upgrade-mosquitto
  • ubuntu-upgrade-mosquitto-clients
