Description

Red Hat JBoss Fuse Service Works is the next-generation ESB and business
process automation infrastructure.

This release of Red Hat JBoss Fuse Service Works 6.2.1 serves as a
replacement 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 fixed with this release:

A flaw was discovered that when an application uses Groovy (has it on the
classpath) and uses the standard Java serialization mechanism, an attacker
can bake a special serialized object that executes code directly when
deserialized. All applications which rely on serialization and do not
isolate the code which deserializes objects are subject to this
vulnerability. (CVE-2015-3253)

It was found that Apache Camel's XML converter performed XML External
Entity (XXE) expansion. A remote attacker able to submit an SAXSource
containing an XXE declaration could use this flaw to read files accessible
to the user running the application server, and potentially perform other
more advanced XXE attacks. (CVE-2015-0263)

It was found that Apache Camel performed XML External Entity (XXE)
expansion when evaluating invalid XML Strings or invalid XML GenericFile
objects. A remote attacker able to submit a crafted XML message could use
this flaw to read files accessible to the user running the application
server, and potentially perform other more advanced XXE attacks.
(CVE-2015-0264)

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 security update.

Solution

process.
