Synopsis

Important: jbossws-common security update

Type/Severity

Security Advisory: Important

Topic

An updated jbossws-common package that fixes one security issue is now
available for JBoss Enterprise Web Platform 5.1.1 for Red Hat Enterprise
Linux 4, 5, and 6.

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.

Description

The jbossws-common package provides JBoss Web Services Native, a web
service framework included as part of JBoss Enterprise Web 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. This flaw did not affect systems using JBoss Web
Services CXF (provided by jbossas-ws-cxf-ewp). (CVE-2011-1483)

Warning: Before applying this update, please back up your JBoss Enterprise
Web Platform's "jboss-as-web/server/[PROFILE]/deploy/" directory, along
with all other customized configuration files.

Users of JBoss Web Services Native should upgrade to this updated package,
which corrects this issue. The JBoss server process must be restarted for
this update to take effect.

Solution

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
