2. Description:

JBoss Web Services Native is a web service framework included as part of
JBoss Enterprise Portal 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 Portal Platform 4.3.CP06 as provided from
the Red Hat Customer Portal are advised to install this update.

all applications deployed on JBoss Enterprise Portal Platform, along with
all customized configuration files.

The JBoss server process must be restarted for this update to take effect.
