<define-tag description>LTS security update</define-tag>
<define-tag moreinfo>
<p>Several security vulnerabilities have been discovered in ActiveMQ, a Java
message broker.</p>
<ul>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2020-13920">CVE-2020-13920</a>
<p>Apache ActiveMQ uses LocateRegistry.createRegistry() to create the JMX RMI
registry and binds the server to the <q>jmxrmi</q> 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.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2021-26117">CVE-2021-26117</a>
<p>The optional ActiveMQ LDAP login module can be configured to use anonymous
access to the LDAP server.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2023-46604">CVE-2023-46604</a>
<p>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
classpath.</p></li>
</ul>
<p>For Debian 10 buster, these problems have been fixed in version
5.15.16-0+deb10u1.</p>
<p>We recommend that you upgrade your activemq packages.</p>
