Mosquitto 1.5.3 has been released to address a security vulnerability. It also
includes other bug fixes.
# CVE-2018-12543
A vulnerability exists in Mosquitto versions 1.5 to 1.5.2 inclusive, known as
[CVE-2018-12543].
If a message received by the broker has a topic that begins with `$`, but that
does not begin `$SYS`, an assert is triggered that should otherwise not be
accessible, causing Mosquitto to exit.
The issue is fixed in Mosquitto 1.5.3. Patches for older versions are
available at <https://mosquitto.org/files/cve/2018-12543>
The fix addresses the problem by reverting a commit that intended to remove
some unused checks, but also stopped part of the topic hierarchy being created.
# Version 1.5.3 Changes
The complete list of fixes addressed in version 1.5.3 is:
## Security
* Fix [CVE-2018-12543]. If a message is sent to Mosquitto with a topic that
begins with `$`, but is not `$SYS`, then an assert that should be unreachable
is triggered and Mosquitto will exit.
## Broker
* Elevate log level to warning for situation when socket limit is hit.
* Remove requirement to use `user root` in snap package config files.
* Fix retained messages not sent by bridges on outgoing topics at the first
connection. Closes [#701].
* Documentation fixes. Closes [#520], [#600].
* Fix duplicate clients being added to by_id hash before the old client was
removed. Closes [#645].
* Fix Windows version not starting if `include_dir` did not contain any files.
Closes [#566].
## Build
* Various fixes to ease building.
