2. Description:

Red Hat JBoss BRMS is a business rules management system for the
management, storage, creation, modification, and deployment of JBoss Rules.

This release of Red Hat JBoss BRMS 6.0.2 serves as a replacement for Red
Hat JBoss BRMS 6.0.1, and includes bug fixes and enhancements. Refer to the
Red Hat JBoss BRMS 6.0.2 Release Notes for information on the most
significant of these changes. The Release Notes will be available shortly
at https://access.redhat.com/site/documentation/en-US/Red_Hat_JBoss_BRMS/

The following security issues are fixed with this release:

It was found that the secure processing feature of Xalan-Java had
insufficient restrictions defined for certain properties and features.
A remote attacker able to provide Extensible Stylesheet Language
Transformations (XSLT) content to be processed by an application using
Xalan-Java could use this flaw to bypass the intended constraints of the
secure processing feature. Depending on the components available in the
classpath, this could lead to arbitrary remote code execution in the
context of the application server running the application that uses
Xalan-Java. (CVE-2014-0107)

It was found that the ServerTrustManager in the Smack XMPP API did not
verify basicConstraints and nameConstraints in X.509 certificate chains.
A man-in-the-middle attacker could use this flaw to spoof servers and
obtain sensitive information. (CVE-2014-0363)

It was found that the ParseRoster component in the Smack XMPP API did not
verify the From attribute of a roster-query IQ stanza. A remote attacker
could use this flaw to spoof IQ responses. (CVE-2014-0364)

A flaw was found in the WebSocket08FrameDecoder implementation that could
allow a remote attacker to trigger an Out Of Memory Exception by issuing a
series of TextWebSocketFrame and ContinuationWebSocketFrames. Depending on
the server configuration, this could lead to a denial of service.
(CVE-2014-0193)

Red Hat would like to thank James Roper of Typesafe for reporting the
CVE-2014-0193 issue.

All users of Red Hat JBoss BRMS 6.0.1 as provided from the Red Hat Customer
Portal are advised to upgrade to Red Hat JBoss BRMS 6.0.2.

3. Solution:

The References section of this erratum contains a download link (you must
log in to download the update). 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, and then after installing the
update, restart the server by starting the JBoss Application Server
process.
