=====================================================================

1. Summary:

An update is now available for Red Hat JBoss Fuse and Red Hat JBoss A-MQ.

Red Hat Product Security has rated this update as having a security impact
of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) in the References section.

2. Description:

Red Hat JBoss Fuse, based on Apache ServiceMix, provides a small-footprint,
flexible, open source enterprise service bus and integration platform. Red
Hat JBoss A-MQ, based on Apache ActiveMQ, is a standards compliant
messaging system that is tailored for use in mission critical applications.

This patch is an update to Red Hat JBoss Fuse 6.3 and Red Hat JBoss A-MQ
6.3. It includes bug fixes and enhancements, which are documented in the
readme.txt file included with the patch files.

Security Fix(es):

* It was found that ResourceServlet in Spring Framework does not sanitize
the paths that have been provided properly. An attacker can utilize this
flaw to conduct directory traversal attacks. (CVE-2016-9878)

* A vulnerability was discovered in Apache Thrift client libraries that
allows remote, authenticated attackers to cause an infinite recursion via
vectors involving the skip function, resulting in a denial of service (DoS)
condition. (CVE-2015-3254)

* A vulnerability was discovered in JSch that allows a malicious sftp
server to force a client-side relative path traversal in jsch's
implementation for recursive sftp-get. An attacker could leverage this to
write files outside the client's download basedir with effective
permissions of the jsch sftp client process. (CVE-2016-5725)

3. Solution:

Before applying the update, back up your existing installation, including
all applications, configuration files, databases and database settings, and
so on.
