Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated Messaging component packages that fix one security issue, several bugs, and add various enhancements are now available for Red Hat Enterprise MRG 2.5 for Red Hat Enterprise Linux 5.

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

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

MRG Messaging is a high-speed reliable messaging distribution for Linux based on AMQP (Advanced Message Queuing Protocol), an open protocol standard for enterprise messaging that is designed to make mission critical messaging widely available as a standard service, and to make enterprise messaging interoperable across platforms, programming languages, and vendors. MRG Messaging includes an AMQP 0-10 messaging broker; AMQP 0-10 client libraries for C++, Java JMS, and Python; as well as persistence libraries and management tools.

It was found that MRG Management Console (cumin) used the crypt(3) DES-based hash function to hash passwords. DES-based hashing has known weaknesses that allow an attacker to more easily recover plain text passwords from hashes via brute-force guessing. An attacker able to compromise a cumin user database could potentially use this flaw to recover plain text passwords from the password hashes stored in that database. (CVE-2013-6445)

Note: In deployments where user account information is stored in a database managed by cumin, it is recommended that users change their passwords after this update is applied.

This issue was discovered by Tomas Novacik of the Red Hat MRG Quality Engineering team.

This update also fixes several bugs and adds enhancements.
Documentation for these changes will be available shortly from the Technical Notes document linked to in the References section.

All users of the Messaging capabilities of Red Hat Enterprise MRG are advised to upgrade to these updated packages, which resolve these issues and add these enhancements. After installing the updated packages, stop the cluster by either running 'service qpidd stop' on all nodes, or 'qpid-cluster --all-stop' on any one of the cluster nodes. Once stopped, restart the cluster with 'service qpidd start' on all nodes for the update to take effect.

Solution

Update the affected cumin and / or mrg-release packages.
