Hat Decision Manager 7.3.1, and includes bug fixes and enhancements, which
are documented in the Release Notes document linked to in the References.

Security Fix(es):

* jackson-databind: Potential information exfiltration with default typing,
serialization gadget from MyBatis (CVE-2018-11307)

* jackson-databind: improper polymorphic deserialization of types from
Jodd-db library (CVE-2018-12022)

* jackson-databind: improper polymorphic deserialization of types from
Oracle JDBC driver (CVE-2018-12023)

* jackson-databind: arbitrary code execution in slf4j-ext class
(CVE-2018-14718)

* jackson-databind: arbitrary code execution in blaze-ds-opt and

* jackson-databind: improper polymorphic deserialization in openjpa class
(CVE-2018-19361)

* jackson-databind: improper polymorphic deserialization in
jboss-common-core class (CVE-2018-19362)

* jackson-databind: exfiltration/XXE in some JDK classes (CVE-2018-14720)

* jackson-databind: server-side request forgery (SSRF) in axis2-jaxws class
(CVE-2018-14721)

* xstream: remote code execution due to insecure XML deserialization
(CVE-2019-10173, regression of CVE-2013-7285)
