Doc Text:
A flaw was found in Apache Qpid Broker-J within the Advanced Message Queuing Protocol (AMQP) 0-10 decoder component. An unauthenticated remote attacker could exploit improper type size and count handling by sending specially crafted network messages. This can trigger excessive memory allocation, resulting in a Denial of Service (DoS) due to resource exhaustion.
