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.
