Hi,

the following vulnerability was published for activemq. I'm not very
familiar with activemq itself, so I'm reporting this with initial
severity grave, but let me know if you disagree.

CVE-2015-5254[0]:
Unsafe deserialization

Upstream advisory is at [1]:
| Description:
|
| JMS Object messages depends on Java Serialization for marshaling/unmashaling
| of the message payload. There are a couple of places inside the broker where
| deserialization can occur, like web console or stomp object message
| transformation. As deserialization of untrusted data can leaed to security
| flaws as demonstrated in various reports, this leaves the broker vunerable to
| this attack vector. Additionally, applications that consume ObjectMessage type
| of messages can be vunerable as they deserlize objects on
| ObjectMessage.getObject() calls.
|
| Mitigation:
|
| Upgrade to Apache ActiveMQ 5.13.0. Additionally if you're using ObjectMessage
| message type, you need to explicitly list trusted packages. To see how to do
| that, please take a look at: http://activemq.apache.org/objectmessage.html

If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
