Description

Updated Red Hat Enterprise Messaging, Realtime, and Grid (MRG) Realtime packages that fix multiple security issues and add one enhancement are now available for Red Hat Enterprise MRG 2.5.

Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Red Hat Enterprise MRG is a next-generation IT infrastructure for enterprise computing. MRG offers increased performance, reliability, interoperability, and faster computing for enterprise customers.
