**Summary** A flaw in the `recvContent` function allows a malicious AMQP server to trigger an Out-of-Memory (OOM) error, forcing the host operating system or container runtime to immediately terminate the client process. **Vulnerability Details** When receiving message content payloads, the client processes the expected size from the content header framework.
