Doc Text:
A flaw was found in Apache Qpid Broker-J. An unauthenticated remote attacker could exploit this vulnerability by sending specially crafted messages with manipulated type size or count parameters to the AMQP (Advanced Message Queuing Protocol) decoder. This causes excessive memory allocation, leading to a Denial of Service (DoS) by exhausting available system resources.
