-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: Red Hat Enterprise MRG Messaging 2.2 update Advisory ID: RHSA-2012:1277-01 Product: Red Hat Enterprise MRG for RHEL-5 Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-1277.html Issue date: 2012-09-19 CVE Names: CVE-2012-2145 CVE-2012-3467 ===================================================================== 1. Summary: Updated Messaging component packages that fix two security issues, multiple bugs, and add various enhancements are now available for Red Hat Enterprise MRG 2.2 for Red Hat Enterprise Linux 5. The Red Hat Security Response Team 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. 2. Relevant releases/architectures: MRG Grid Execute Node for RHEL 5 Server v.2 - noarch MRG Grid for RHEL 5 Server v.2 - noarch MRG Management for RHEL 5 Server v.2 - noarch Red Hat MRG Messaging for RHEL 5 Server v.2 - i386, noarch, x86_64 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 Apache Qpid daemon (qpidd) did not allow the number of connections from clients to be restricted. A malicious client could use this flaw to open an excessive amount of connections, preventing other legitimate clients from establishing a connection to qpidd. (CVE-2012-2145) To address CVE-2012-2145, new qpidd configuration options were introduced: max-negotiate-time defines the time during which initial protocol negotiation must succeed, connection-limit-per-user and connection-limit-per-ip can be used to limit the number of connections per user and client host IP. Refer to the qpidd manual page for additional details. It was discovered that qpidd did not require authentication for "catch-up" shadow connections created when a new broker joins a cluster. A malicious client could use this flaw to bypass client authentication. (CVE-2012-3467) This update also fixes multiple 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 2.2 are advised to upgrade to these updated packages, which resolve the issues and add the enhancements 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/knowledge/articles/11258 5. Bugs fixed (http://bugzilla.redhat.com/): 689408 - ACL denials while replicating exclusive queues to a newly joined node 693444 - Inconsistency in clients on reliability of receiver link from exchange 809357 - "qpid-perftest.exe" and "qpid-latency-test.exe" fail with option "--tcp-nodelay" on Windows 817175 - CVE-2012-2145 qpid-cpp: not closing incomplete connections exhausts file descriptors, leading to DoS 836276 - CVE-2012-3467 qpid-cpp-server-cluster: unauthorized broker access caused by the use of NullAuthenticator catch-up shadow connections 841488 - qpid-stat does not support multi-byte characters (UTF-8) 6.
