GHSA-5XWG-CFVJ-GFF5 RabbitMQ Java client accepts broker frames larger than the negotiated AMQP frame_max

Summary The max body size was enforced to patch CVE-2023-46120, but even though that limit still works, the frame size itself still exceeds the given max size. Root cause The Java client records the AMQP 0-9-1 framemax negotiated during connection tuning, but the socket inbound frame reader...

RabbitMQ Java client malformed body frame triggers raw command assembler exception

Summary RabbitMQ Java Client's inbound AMQP command assembly accepts a content header declaring a small body and then processes a larger body frame by throwing a raw UnsupportedOperationException from CommandAssembler. A broker peer that the client has connected to can use this malformed frame...
