3. Description:

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 discovered that the Qpid Python client library for AMQP did not properly perform TLS/SSL certificate validation of the remote server's certificate, even when the 'ssl_trustfile' connection option was specified. A rogue server could use this flaw to conduct man-in-the-middle attacks, possibly leading to the disclosure of sensitive information. (CVE-2013-1909)

With this update, Python programs can instruct the library to validate server certificates by specifying a path to a file containing trusted CA certificates.

This issue was discovered by Petr Matousek of the Red Hat MRG Messaging team.

This update also fixes multiple bugs. 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 2.3 are advised to upgrade to these updated packages, which resolve the issues noted in the Red Hat Enterprise MRG 2 Technical Notes. 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.

4. Solution:

Before applying this update, make sure all previously released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/site/articles/11258

5. Bugs fixed (http://bugzilla.redhat.com/):

928530 - CVE-2013-1909 python-qpid: client does not validate qpid server TLS/SSL certificate
