1. Summary:

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

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 6.4.6 serves as a replacement for
Red Hat JBoss BPM Suite 6.4.5, 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 when using remote logging with log4j socket server the
log4j server would deserialize any log event received via TCP or UDP. An
attacker could use this flaw to send a specially crafted log event that,
during deserialization, would execute arbitrary code in the context of the
logger application. (CVE-2017-5645)

* It was found that XStream contains a vulnerability that allows a
maliciously crafted file to be parsed successfully which could cause an
application crash. The crash occurs if the file that is being fed into
XStream input stream contains an instances of the primitive type ‘void’. An
attacker could use this flaw to create a denial of service on the target
system. (CVE-2017-7957)

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.
