1. Summary:

An update is now available for Red Hat JBoss BPM Suite.

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:

This release of Red Hat JBoss BPM Suite 6.4.0 serves as a replacement for
Red Hat JBoss BPM Suite 6.3.4, and includes bug fixes and enhancements,
which are documented in the Release Notes of the patch linked to in the
References section.

Security Fix(es):

* It was found that several XML parsers used by XStream had default
settings that would expand entity references. A remote, unauthenticated
attacker could use this flaw to read files accessible to the user running
the application server, and potentially perform other more advanced XXE
attacks. (CVE-2016-3674)

* Drools Workbench contains the path traversal vulnerability. The
vulnerability allows a remote, authenticated attacker to bypass the
directory restrictions and retrieve arbitrary files from the affected host.
(CVE-2016-7041)

* JBoss BRMS 6 and BPM Suite 6 are vulnerable to a stored XSS via business
process editor. The flaw is due to an incomplete fix for CVE-2016-5398.
Remote, authenticated attackers that have privileges to create business
processes can store scripts in them, which are not properly sanitized
before showing to other users, including admins. (CVE-2016-8608)

Red Hat would like to thank Jonas Bauters (NVISO) for reporting
CVE-2016-7041. The CVE-2016-8608 issue was discovered by Kirill Gaevskii
(Red Hat).

3. Solution:

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

It is recommended to halt the server by stopping the JBoss Application
Server process before installing this update; after installing the update,
restart the server by starting the JBoss Application Server process.
