説明

Red Hat JBoss Fuse Service Works is the next-generation ESB and business
process automation infrastructure. Red Hat JBoss Fuse Service Works allows
IT to leverage existing (MoM and EAI), modern (SOA and BPM-Rules), and
future (EDA and CEP) integration methodologies to dramatically improve
business process execution speed and quality.

This roll up patch serves as a cumulative upgrade for Red Hat JBoss Fuse
Service Works 6.0.0. It includes various bug fixes, which are listed in the
README file included with the patch files.

The following security issues are also fixed with this release:

It was found that the Apache Camel XSLT component allowed XSL stylesheets
to call external Java methods. A remote attacker able to submit messages to
a Camel route could use this flaw to perform arbitrary remote code
execution in the context of the Camel server process. (CVE-2014-0003)

It was found that when JBoss Web processed a series of HTTP requests in
which at least one request contained either multiple content-length
headers, or one content-length header with a chunked transfer-encoding
header, JBoss Web would incorrectly handle the request. A remote attacker
could use this flaw to poison a web cache, perform cross-site scripting
(XSS) attacks, or obtain sensitive information from other requests.
(CVE-2013-4286)

It was found that the Apache Camel XSLT component would resolve entities in
XML messages when transforming them using an XSLT route. A remote attacker
able to submit messages to an XSLT Camel route could use this flaw to read
files accessible to the user running the application server and,
potentially, perform other more advanced XML External Entity (XXE) attacks.
(CVE-2014-0002)

A denial of service flaw was found in the way Apache Commons FileUpload,
which is embedded in the JBoss Web component of JBoss EAP, handled
small-sized buffers used by MultipartStream. A remote attacker could use
this flaw to create a malformed Content-Type header for a multipart
request, causing JBoss Web to enter an infinite loop when processing such
an incoming request. (CVE-2014-0050)

The CVE-2014-0002 and CVE-2014-0003 issues were discovered by David Jorm of
the Red Hat Security Response Team.

All users of Red Hat JBoss Fuse Service Works 6.0.0 as provided from the
Red Hat Customer Portal are advised to apply this roll up patch.
