Type/Severity

Security Advisory: Moderate

Topic

Updated qpid-cpp packages that fix multiple security issues and one bug are
now available for Red Hat Enterprise MRG Messaging 2.5 for Red Hat
Enterprise Linux 7.

Red Hat Product Security 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.

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.

The Qpid packages provide a message broker daemon that receives, stores and
routes messages using the open AMQP messaging protocol along with run-time
libraries for AMQP client applications developed using Qpid C++. Clients
exchange messages with an AMQP message broker using the AMQP protocol.

It was discovered that the Qpid daemon (qpidd) did not restrict access to
anonymous users when the ANONYMOUS mechanism was disallowed.
(CVE-2015-0223)

Multiple flaws were found in the way the Qpid daemon (qpidd) processed
certain protocol sequences. An unauthenticated attacker able to send a
specially crafted protocol sequence set could use these flaws to crash
qpidd. (CVE-2015-0203, CVE-2015-0224)

Red Hat would like to thank the Apache Software Foundation for reporting
the CVE-2015-0203 issue. Upstream acknowledges G. Geshev from MWR Labs as
the original reporter.

This update also fixes the following bug:

• Prior to this update, because message purging was performed on a timer
  thread, large purge events could have caused all other timer tasks to be
  delayed. Because heartbeats were also driven by a timer on this thread,
  this could have resulted in clients timing out because they were not
  receiving heartbeats. The fix moves expired message purging from the timer
  thread to a worker thread, which allow long-running expired message purges
  to not affect timer tasks such as the heartbeat timer. (BZ#1142833)
  

All users of Red Hat Enterprise MRG Messaging 2.5 for Red Hat Enterprise
Linux 7 are advised to upgrade to these updated packages, which correct
these issues.
