Resumen:	NOSUMMARY
Descripción:	Description: The remote host is missing updates announced in advisory RHSA-2012:1277. 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. Solution: Please note that this update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date http://rhn.redhat.com/errata/RHSA-2012-1277.html Risk factor : Medium
