Título:	RedHat Security Advisory RHSA-2012:0528
Resumen:	NOSUMMARY
Descripción:	Description: The remote host is missing updates announced in advisory RHSA-2012:0528. 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 Qpid accepted any password or SASL mechanism, provided the remote user knew a valid cluster username. This could give a remote attacker unauthorized access to the cluster, exposing cluster messages and internal Qpid/MRG configurations. (CVE-2011-3620) Note: If you are using an ACL, the cluster-username must be allowed to publish to the qpid.cluster-credentials exchange. For example, if your cluster-username is foo, in your ACL file: acl allow foo@QPID publish exchange name=qpid.cluster-credentials The CVE-2011-3620 fix changes the cluster initialization protocol. As such, the cluster with all new version brokers must be restarted for the changes to take effect. Refer below for details. These updated packages provide numerous enhancements and bug fixes for the Messaging component of MRG. Space precludes documenting all of these changes in this advisory. Documentation for these changes will be available shortly in the Technical Notes document linked to in the References section. All users of the Messaging capabilities of Red Hat Enterprise MRG 2.1 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-2012-0528.html http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_MRG/2/html-single/Technical_Notes/index.html#RHSA-2012-0528 Risk factor : Medium
