RabbitMQ -- Denial of Service via improper input validation

Jonathon Knudsen of Synopsys Cybersecurity Research Center reports:

All versions prior to 3.8.16 are prone to a denial of service
vulnerability due to improper input validation in AMQP 1.0 client
connection endpoint. A malicious client can exploit the vulnerability
by sending malicious AMQP messages to the target RabbitMQ instance
having the AMQP 1.0 plugin enabled.
