CVE ID         : CVE-2017-15709 CVE-2018-11775 CVE-2019-0222

Debian Bug     : 890352 908950 982590

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.
