Security Fix(es) :

* A deserialization flaw was discovered in jackson-databind which
could allow an unauthenticated user to perform code execution by
sending maliciously crafted input to the readValue method of the
ObjectMapper. (CVE-2017-7525)

* It was found that use of a JMS ObjectMessage does not safely handle
user-supplied data when deserializing objects. A remote attacker could
use this flaw to execute arbitrary code with the permissions of the
application using the JMS ObjectMessage. (CVE-2016-4978)

Red Hat would like to thank Liao Xinxi (NSFOCUS) for reporting
CVE-2017-7525.
