Overview
Affected versions of this package are vulnerable to Improper Check for Unusual or Exceptional Conditions through the consumeBodyFrame path in CommandAssembler. An attacker can crash frame processing and tear down the AMQP connection by sending a content header that declares a small body size followed by a larger body frame on an open channel. The client processes the malformed frame sequence as a raw UnsupportedOperationException, so applications depending on that connection lose the broker session and stop consuming or publishing over it.
