Summary: Updated Red Hat Enterprise MRG Messaging packages that fix two security issues and several bugs are now available 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: Red Hat MRG Messaging Base for RHEL 5 Server - i386, x86_64 Red Hat MRG Messaging for RHEL 5 Server - i386, x86_64 3. Description: Red Hat Enterprise MRG (Messaging, Realtime and Grid) is a real-time IT infrastructure for enterprise computing. MRG Messaging implements the Advanced Message Queuing Protocol (AMQP) standard, adding persistence options, kernel optimizations, and operating system services. A flaw was found in the way SSL connections to the MRG Messaging broker were handled. A connection (from a user or client application) to the broker's SSL port would prevent the broker from responding to any other connections on that port, until the first connection's SSL handshake completed or failed. A remote user could use this flaw to block connections from legitimate clients. Note that this issue only affected connections to the SSL port. The broker does not listen for SSL connections by default. (CVE-2010-3083) A flaw was found in the way the MRG Messaging broker handled the receipt of large persistent messages. If a remote, authenticated user sent a very large persistent message, the broker could exhaust stack memory, causing the broker to crash. (CVE-2010-3701) This update also includes a number of MRG Messaging bug fixes, including updated qpidc and rhm packages: * The Messaging broker failed when first a new durable exchange was supplied by a plug-in, and then the broker was restarted. The startup sequence has been reordered so that the plug-in modules are loaded before the store is recovered. With this update, the new exchange is now recognized and recovered successfully and the broker starts up. (BZ#550151) * qpid-route could not delete an existing route due to a problem with the management object for the bridge. With this update, qpid-route follows the normal path. (BZ#560696) * Previously, clients connecting over SSL needed to use some other username to authenticate themselves to have permission granted via ACLs. This update adds the option to use the client identity as authenticated by SSL. (BZ#601222) * New brokers did not see a durable exchange even though it existed in a cluster. This update checks for any durable exchanges to be replicated when a new broker is added to the cluster. Now, the exchange is visible on the new broker. (BZ#601230) * Cluster members occasionally failed when a new member was added to a cluster with active consumers, because some of the consumer information was not being replicated to new members joining a cluster. With this update, the missing information is replicated to new members when joining a cluster. (BZ#601236) * Performance decreased when reading messages from a queue sequentially without taking them off the queue. With this update, the algorithm for traversing through messages has been changed, and the next message is found more quickly, even for large queues. (BZ#611907) * Wire level protocol violation or segmentation faults occurred when adding tags due to possible modification of the message concurrent with its encoding. This update clones messages before adding tags to prevent concurrent modification as they are being delivered and encoded. (BZ#619919) All Red Hat Enterprise MRG users are advised to upgrade to these updated packages, which correct these issues. After installing the updated packages, the qpidd service must be restarted ("service qpidd restart") for this 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 http://kbase.redhat.com/faq/docs/DOC-11259 5.
