CVE-2016-8741
Exposure of Sensitive Information to an Unauthorized Actor in Apache Qpid Broker for Java

It was discovered that these AuthenticationProviders in Apache Qpid Broker for Java 6.0.x before 6.0.6 and 6.1.x before 6.1.1 prematurely terminate the SCRAM SASL negotiation if the provided user name does not exist thus allowing remote attacker to determine the existence of user accounts.
