1. Summary:

Updated jbossws-client.jar, jbossws-common.jar, jbossws-core.jar, and
jbossws-native-core.jar files for JBoss Enterprise SOA Platform 4.2.CP05,
4.3.CP05, and 5.1.0 that fix one security issue are now available from

CVE link in the References section.

2. Description:

JBoss Web Services Native is a web service framework included as part of
JBoss Enterprise SOA Platform. It implements the JAX-WS specification.

It was found that JBoss Web Services Native did not properly protect
against recursive entity resolution when processing Document Type
Definitions (DTD). A remote attacker could exploit this flaw by sending a
specially-crafted HTTP POST request to a deployed web service, causing
excessive CPU and memory consumption on the system hosting that service. If
the attack is repeated to consume all available network sockets, the server
will become unavailable. (CVE-2011-1483)

All users of JBoss Enterprise SOA Platform 4.2.CP05, 4.3.CP05, and 5.1.0 as
provided from the Red Hat Customer Portal are advised to install this
update.

3. Solution:

The References section of this erratum contains download links (you must
log in to download the updated files). Before applying the update, back up
your existing JBoss Enterprise SOA Platform installation (including its
databases, applications, configuration files, and so on).

The updates for JBoss Enterprise SOA Platform 4.2.CP05 and 4.3.CP05 contain
updated jbossws-client.jar, jbossws-common.jar, and jbossws-core.jar files.
The update for JBoss Enterprise SOA Platform 5.1.0 contains updated
jbossws-common.jar and jbossws-native-core.jar files. Refer to the
"README.text" file in each download for installation instructions.

Note that it is recommended to halt the JBoss Enterprise SOA Platform
server by stopping the JBoss Application Server process before installing
this update, and then after installing the update, restart the JBoss
Enterprise SOA Platform server by starting the JBoss Application Server
process.
