Several security vulnerabilities have been discovered in ActiveMQ, a Java
message broker.


 Apache ActiveMQ uses LocateRegistry.createRegistry() to create the JMX RMI
 registry and binds the server to the "jmxrmi" entry. It is possible to connect
 to the registry without authentication and call the rebind method to rebind
 jmxrmi to something else. If an attacker creates another server to proxy the
 original, and bound that, he effectively becomes a man in the middle and is
 able to intercept the credentials when an user connects.


 The optional ActiveMQ LDAP login module can be configured to use anonymous
 access to the LDAP server.


 The Java OpenWire protocol marshaller is vulnerable to Remote Code Execution.
 This vulnerability may allow a remote attacker with network access to either a
 Java-based OpenWire broker or client to run arbitrary shell commands by
 manipulating serialized class types in the OpenWire protocol to cause either
 the client or the broker (respectively) to instantiate any class on the 

For Debian 10 buster, these problems have been fixed in version

We recommend that you upgrade your activemq packages.
