------------------------------------------------------------------------------- - Fedora Update Notification FEDORA-2019-8b83c261dd 2019-10-04 21:23:34.757643 ------------------------------------------------------------------------------- -
Name : mosquitto Product : Fedora 30 Version : 1.6.7 Release : 1.fc30 URL : http://mosquitto.org/ Summary : An Open Source MQTT v3.1/v3.1.1 Broker Description : Mosquitto is an open source message broker that implements the MQ Telemetry Transport protocol version 3.1 and 3.1.1 MQTT provides a lightweight method of carrying out messaging using a publish/subscribe model. This makes it suitable for "machine to machine" messaging such as with low power sensors or mobile devices such as phones, embedded computers or micro-controllers like the Arduino.
------------------------------------------------------------------------------- - Update Information:
1.6.7 ===== Broker: * Add workaround for working with libwebsockets 3.2.0. * Fix potential crash when reloading config. Client library: * Don't use / in autogenerated client ids, to avoid confusing with topics. * Fix mosquitto_max_inflight_messages_set() and mosquitto_int_option(..., MOSQ_OPT_*_MAX, ...) behaviour. * Fix regression on use of mosquitto_connect_async() not working. Clients: * mosquitto_sub: Fix -E incorrectly not working unless -d was also specified. * Updated documentation around automatic client ids. 1.6.6 ===== Security: * CVE-2019-11779 * Restrict topic hierarchy to 200 levels to prevent possible stack overflow. Broker: * Restrict topic hierarchy to 200 levels to prevent possible stack overflow. * mosquitto_passwd now returns 1 when attempting to update a user that does not exist. 1.6.5 ===== Broker: * Fix v5 DISCONNECT packets with remaining length == 2 being treated as a protocol error. * Fix support for libwebsockets 3.x. * Fix slow websockets performance when sending large messages. * Fix bridges potentially not connecting on Windows. * Fix clients authorised using `use_identity_as_username` or `use_subject_as_username` being disconnected on SIGHUP. * Improve error messages in some situations when clients disconnect. Reduces the number of "Socket error on client X, disconnecting" messages. * Fix Will for v5 clients not being sent if will delay interval was greater than the session expiry interval. * Fix CRL file not being reloaded on HUP. * Fix repeated "Error in poll" messages on Windows when only websockets listeners are defined. Client library: * Fix reconnect backoff for the situation where connections are dropped rather than refused. * Fix missing locks on `mosq->state`. Documentation: * Improve details on global/per listener options in the mosquitto.conf man page. * Clarify behaviour when clients exceed the `message_size_limit`. * Improve documentation for `max_inflight_bytes`, `max_inflight_messages`, and `max_queued_messages`. ------------------------------------------------------------------------------- - ChangeLog:
