Raw Blame History

Versions 2.0.11 of Mosquitto has been released. This is a security and bugfix release.

Security

  • If an authenticated client connected with MQTT v5 sent a crafted CONNECT message to the broker a memory leak would occur. Affects versions 1.6 to 2.0.10 inclusive.

Broker

  • Fix possible crash having just upgraded from 1.6 if per_listener_settings true is set, and a SIGHUP is sent to the broker before a client has reconnected to the broker. Closes #2167.
  • Fix bridge not reconnectng if the first reconnection attempt fails. Closes #2207.
  • Improve QoS 0 outgoing packet queueing.
  • Fix non-reachable bridge blocking the broker on Windows. Closes #2172.
  • Fix possible corruption of pollfd array on Windows when bridges were reconnecting. Closes #2173.

Clients

  • If sending mosquitto_sub output to a pipe, mosquitto_sub will now detect that the pipe has closed and disconnect. Closes #2164.
  • Fix mosquitto_pub -l quitting if a message publication is attempted when the broker is temporarily unavailable. Closes #2187.
