                   Red Hat Security Advisory

Synopsis:          Moderate: Red Hat JBoss BPM Suite security update
Advisory ID:       RHSA-2017:1675-01
Product:           Red Hat JBoss BPM Suite
Advisory URL:      https://access.redhat.com/errata/RHSA-2017:1675
Issue date:        2017-07-04
CVE Names:         CVE-2016-6346 CVE-2016-9606 CVE-2017-5929 
=====================================================================

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 6.4.4 serves as a replacement for
Red Hat JBoss BPM Suite 6.4.3, 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 GZIPInterceptor is enabled when not necessarily
required in RESTEasy. An attacker could use this flaw to launch a Denial of
Service attack. (CVE-2016-6346)

* It was discovered that under certain conditions RESTEasy could be forced
to parse a request with YamlProvider, resulting in unmarshalling of
potentially untrusted data. An attacker could possibly use this flaw
execute arbitrary code with the permissions of the application using
RESTEasy. (CVE-2016-9606)

* It was found that logback is vulnerable to a deserialization issue.
Logback can be configured to allow remote logging through
SocketServer/ServerSocketReceiver interfaces that can accept untrusted
serialized data. Authenticated attackers on the adjacent network can
leverage this vulnerability to execute arbitrary code through
deserialization of custom gadget chains. (CVE-2017-5929)

Red Hat would like to thank Mikhail Egorov (Odin) for reporting
CVE-2016-6346 and Moritz Bechler (AgNO3 GmbH & Co. KG) for reporting
CVE-2016-9606.

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
log in to download the update).

4. Bugs fixed (https://bugzilla.redhat.com/):

1372120 - CVE-2016-6346 RESTEasy: Abuse of GZIPInterceptor in RESTEasy can lead to denial of service attack
1400644 - CVE-2016-9606 Resteasy: Yaml unmarshalling vulnerable to RCE
1432858 - CVE-2017-5929 logback: Serialization vulnerability in SocketServer and ServerSocketReceiver
