More information:

Multiple security issues were discovered in activemq, a message broker built around Java Message Service.

  • CVE-2017-15709

    When using the OpenWire protocol in activemq, it was found that certain system details (such as the OS and kernel version) are exposed as plain text.

  • CVE-2018-11775

    TLS hostname verification when using the Apache ActiveMQ Client was missing which could make the client vulnerable to a MITM attack between a Java application using the ActiveMQ client and the ActiveMQ server. This is now enabled by default.

  • CVE-2019-0222

    Unmarshalling corrupt MQTT frame can lead to broker Out of Memory exception making it unresponsive

  • CVE-2021-26117

    The optional ActiveMQ LDAP login module can be configured to use anonymous access to the LDAP server. The anonymous context is used to verify a valid users password in error, resulting in no check on the password.

For Debian 9 stretch, these problems have been fixed in version 5.14.3-3+deb9u2.

We recommend that you upgrade your activemq packages.
