1. Summary:

An update is now available for Red Hat Decision Manager.

Red Hat Product Security has rated this update as having a security impact
of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) in the References section.

2. Description:

Red Hat Decision Manager is an open source decision management platform
that combines business rules management, complex event processing, Decision
Model & Notation (DMN) execution, and Business Optimizer for solving
planning problems. It automates business decisions and makes that logic
available to the entire business.

This release of Red Hat Decision Manager 7.12.0 serves as an update to Red
Hat Decision Manager 7.11.1, and includes bug fixes and enhancements, which
are documented in the Release Notes document linked to in the References.

* jackson-dataformat-cbor:  Unchecked allocation of byte buffer can cause a
java.lang.OutOfMemoryError exception (CVE-2020-28491)

* kubernetes-client: fabric8-kubernetes-client: vulnerable to a path
traversal leading to integrity and availability compromise (CVE-2021-20218)
