CWE: CWE-400 \u2014 Uncontrolled Resource Consumption
The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources.

Code:
    private void consumeHeaderFrame(Frame f) throws IOException {
        if (f.type == AMQP.FRAME_HEADER) {
            this.contentHeader = AMQImpl.readContentHeaderFrom(f.getInputStream());
            this.remainingBodyBytes = this.contentHeader.getBodySize();
            updateContentBodyState();
        } else {
            throw new UnexpectedFrameError(f, AMQP.FRAME_HEADER);
        }
    }
