A specifically malformed MQTT Subscribe packet crashes MQTT Brokers using the mqtt-packet module versions < 3.5.1, 4.0.0 - 4.1.3, 5.0.0 - 5.6.1, 6.0.0 - 6.1.2 for decoding.

Affected

Our own answer: ranges merged, affected separated from platform-only, with confidence and review flags.

v < 3.5.14.0.0 ≤ v ≤ 4.1.35.0.0 ≤ v ≤ 5.6.16.0.0 ≤ v ≤ 6.1.2
Affected range stops below 3.5.1, so it looks safe — our inference, not a vendor statement
