- Update to version 1.4.15
Security:
* Fix CVE-2017-7652. If a SIGHUP is sent to the broker when there are no more
file descriptors, then opening the configuration file will fail and security
settings will be set back to their default values.
* Fix CVE-2017-7651. Unauthenticated clients can cause excessive memory use by
setting "remaining length" to be a large value. This is now mitigated by
limiting the size of remaining length to valid values. A "memory_limit"
configuration option has also been added to allow the overall memory used by
the broker to be limited.
Broker:
* Use constant time memcmp for password comparisons.
* Fix incorrect PSK key being used if it had leading zeroes.
* Fix memory leak if a client provided a username/password for a listener with
use_identity_as_username configured.
* Fix use_identity_as_username not working on websockets clients.
* Don't crash if an auth plugin returns MOSQ_ERR_AUTH for a username check on
a websockets client. Closes#490.
* Fix 08-ssl-bridge.py test when using async dns lookups. Closes#507.
* Lines in the config file are no longer limited to 1024 characters long.
Closes#652.
* Fix $SYS counters of messages and bytes sent when message is sent over
a Websockets. Closes#250.
* Fix upgrade_outgoing_qos for retained message. Closes#534.
* Fix CONNACK message not being sent for unauthorised connect on websockets.
Closes#8.
Client library:
* Fix incorrect PSK key being used if it had leading zeroes.

- Update to 1.4.13
* Security:
- Fix CVE-2017-9868. The persistence file was readable
by all local users, potentially allowing sensitive
information to be leaked.
This can also be fixed administratively, by restricting
access to the directory in which the persistence file
is stored.
* Broker:
- Fix for poor websockets performance.
- Fix lazy bridges not timing out for idle_timeout.
- Fix problems with large retained messages over websockets.
- Set persistence file to only be readable by owner,
except on Windows.
- Fix CONNECT check for reserved=0, as per MQTT v3.1.1
check MQTT-3.1.2-3.
- When the broker stop, wills for any connected clients
are now "sent".
- Auth plugins can be configured to disable the check for +# in
usernames/client ids with the auth_plugin_deny_special_chars
option. Partially closes#462.
- Restrictions for CVE-2017-7650 have been relaxed - '/' is
allowed in usernames/client ids. Remainder of fix for #462.
Clients:
- Don't use / in auto-generated client ids.
