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:
Red Hat JBoss BPM Suite is a business rules and processes management system
for the management, storage, creation, modification, and deployment of
JBoss rules and BPMN2-compliant business processes.
This release of Red Hat JBoss BPM Suite 6.4.1 serves as a replacement for
Red Hat JBoss BPM Suite 6.4.0, and includes bug fixes and enhancements,
which are documented in the Release Notes document linked to in the
References.
Security Fix(es):
* It was found that the parsing of XMP and other XML formats in PDF by
Apache PDFBox 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-2016-2175)
* It was found that the parsing of OOXML, XMP in PDF, and some other file
formats by Apache Tika 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-2016-4434)
* It was discovered that JBoss BRMS 6 and BPM Suite 6 are not setting
HttpOnly flags on sensitive cookies. Remote attackers can access these
cookies by using client-side scripts, usually through XSS. Please note that
on IBM WebSphere the HttpOnly flag cannot be set by deployed applications,
it needs to be configured directly on WAS console. (CVE-2016-6344)
* JBoss BRMS 6 and BPM Suite 6 are vulnerable to a stored XSS via
dashbuilder. Remote, authenticated attackers that have privileges to access
dashbuilder (usually admins) can store scripts in several editable fields,
which are not properly sanitized before showing to other users, including
other admins. (CVE-2016-7033)
The CVE-2016-6344 and CVE-2016-7033 issues were discovered by Jeremy Choi
(Red Hat Product Security Team).
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.
The References section of this erratum contains a download link (you must
