Summary
Red Hat Security Advisory: Red Hat JBoss BRMS security update

Notes

Topic
An update is now available for Red Hat JBoss BRMS. 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.
Details
Red Hat JBoss BRMS is a business rules management system for the management, storage, creation, modification, and deployment of JBoss Rules. This release of Red Hat JBoss BRMS 6.4.4 serves as a replacement for Red Hat JBoss BRMS 6.4.3, and includes bug fixes and enhancements, which are documented in the Release Notes document linked to in the References. Security Fix(es): * It was found that GZIPInterceptor is enabled when not necessarily required in RESTEasy. An attacker could use this flaw to launch a Denial of Service attack. (CVE-2016-6346) * It was discovered that under certain conditions RESTEasy could be forced to parse a request with YamlProvider, resulting in unmarshalling of potentially untrusted data. An attacker could possibly use this flaw execute arbitrary code with the permissions of the application using RESTEasy. (CVE-2016-9606) * It was found that logback is vulnerable to a deserialization issue. Logback can be configured to allow remote logging through SocketServer/ServerSocketReceiver interfaces that can accept untrusted serialized data. Authenticated attackers on the adjacent network can leverage this vulnerability to execute arbitrary code through deserialization of custom gadget chains. (CVE-2017-5929) Red Hat would like to thank Mikhail Egorov (Odin) for reporting CVE-2016-6346 and Moritz Bechler (AgNO3 GmbH & Co. KG) for reporting CVE-2016-9606.
