Summary
Red Hat Security Advisory: Red Hat Decision Manager 7.5.0 Security Update

Notes

Topic
An update is now available for Red Hat Decision Manager. Red Hat Product Security has rated this update as having a security impact of Important. 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.
Details
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 7.5.0 serves as an update to Red Hat Decision Manager 7.4.1, and includes bug fixes and enhancements, which are documented in the Release Notes document linked to in the References. Security Fix(es): * jackson-databind: default typing mishandling leading to remote code execution (CVE-2019-14379) * jackson-databind: failure to block the logback-core class from polymorphic deserialization leading to remote code execution (CVE-2019-12384) * jackson-databind: polymorphic typing issue allows attacker to read arbitrary local files on the server via crafted JSON message (CVE-2019-12814) For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.

We may update the jackson-databind dependency in a future release.\n\nRed Hat OpenStack Platform ships OpenDaylight, which contains the vulnerable jackson-databind. However, OpenDaylight does not expose jackson-databind in a way that would make it vulnerable, lowering the impact of the vulnerability for OpenDaylight.
