The remote Red Hat host is missing a security update.
An updated jbossws-common package that fixes one security issue is now
available for JBoss Enterprise Application Platform 4.3 for Red Hat
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.
Warning: Before applying this update, please back up your JBoss
Enterprise Application Platform's 'jboss-as/server/[PROFILE]/deploy/'
directory, along with all other customized configuration files.
Users of JBoss Enterprise Application Platform 4.3 for Red Hat
Enterprise Linux 4 and 5 should upgrade to this updated package, which
corrects this issue. The JBoss server process must be restarted for
this update to take effect.
