RHSA-2016:0308 - Security Advisory
Moderate: rabbitmq-server security and bugfix update
Security Advisory: Moderate
Updated rabbitmq-server packages that fix two security issues and a bug
are now available for Red Hat Enterprise Linux OpenStack Platform
6.0 (Juno) for RHEL 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.
RabbitMQ is an implementation of AMQP, the emerging standard for high
performance enterprise messaging. The RabbitMQ server is a robust and
scalable implementation of an AMQP broker.
A cross-site scripting vulnerability was discovered in RabbitMQ, which
allowed using api/ path info to inject and receive data. A remote
attacker could use this flaw to create an "/api/..." URL, forcing a
server error that resulted in the server returning an HTML page with
embedded text from the URL (not escaped). (CVE-2014-9649)
A response-splitting vulnerability was discovered in RabbitMQ. An
/api/definitions URL could be specified, which then caused an arbitrary
additional header to be returned. A remote attacker could use this flaw
to inject arbitrary HTTP headers and possibly gain access to secure data.
This update also fixes the following bug:
- Previously, if the rabbit_mirror_queue_master did not return when using
HA and 'auto_delete' queues, the RabbitMQ server blocked channels during
termination. These channels would then have no associated connections and
were displayed as 'unknown'. This issue has been resolved. (BZ#1303747)
All rabbitmq-server users are advised to upgrade to these updated packages,
which contain backported patches to correct these issues.
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
