## Description

Apache Qpid AMQP 0-x JMS client before 6.0.4 and JMS (AMQP 1.0) before
0.10.0 does not restrict the use of classes available on the classpath,
which might allow remote authenticated users with permission to send
messages to deserialize arbitrary objects and execute arbitrary code by
leveraging a crafted serialized object in a JMS ObjectMessage that is
handled by the getObject function.
