An updated jbossws-common package that fixes one security issue is now

Enterprise Linux 4 and 5.
The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from the
CVE link in the References section.
The jbossws-common package provides JBoss Web Services Native, a web
service framework included as part of JBoss Enterprise Application
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)
