Description

Roger Light reports:

If an authenticated client connected with MQTT v5 sent

a malformed CONNACK message to the broker a NULL pointer

dereference occurred, most likely resulting in a

segfault.

(Note: a CVE is referenced in the github commit but it

appears to be for a python-bleach vulnerability so it is

not included here.)
