This is a security and bugfix release.
|
||
|
|
|
||
|
|
## Security
|
||
|
|
|
||
|
|
If a client connects using MQTT v5, will a Will message that has MQTT v5
|
||
|
|
properties attached, and the very first Will property is one of `content-type`,
|
||
|
|
`correlation-data`, `payload-format-indicator`, or `response-topic`, then at
|
||
|
|
the point the client disconnects, the broker will attempt to read from freed
|
||
|
|
memory, resulting in a possible crash.
|
||
|
|
|
||
|
|
|
||
|
|
## Broker
|
||
|
|
- Fix memory access after free, leading to possible crash, when v5 client with
|
||
|
|
Will message disconnects, where the Will message has as its first property
|
||
|
|
one of `content-type`, `correlation-data`, `payload-format-indicator`, or
|
||
|
|
`response-topic`. Closes [#1244].
|
||
|
|
- Fix build for `WITH_TLS=no`. Closes [#1250].
|
||
|
|
- Fix Will message not allowing `user-property` properties.
|
||
|
|
- Fix broker originated messages (e.g. `$SYS/broker/version`) not being
|
||
|
|
published when `check_retain_source` set to true. Closes [#1245].
|
||
|
|
- Fix `$SYS/broker/version` being incorrectly expired after 60 seconds.
|
||
|
|
Closes [#1245].
|
||
|
|
|
||
|
|
## Library
|
||
|
|
- Fix crash after client has been unable to connect to a broker. This occurs
|
||
|
|
when the client is exiting and is part of the final library cleanup routine.
|
||
|
|
Closes [#1246].
|
||
|
|
|
||
|
|
## Clients
|
||
|
|
- Fix `-L` url parsing. Closes [#1248].
