Doc Text:
A flaw was found in Spring AMQP. An attacker who can publish to a queue consumed by an application that has enabled message decompression can crash the consumer Java Virtual Machine (JVM) with a single approximately 1 MB message. This unbounded decompression of attacker-supplied compressed message bodies leads to a Denial of Service (DoS).
