New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionUpdated jbossas packages that fix one security issue are now available for JBoss Enterprise Application Platform 4.2.0.CP09 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.
JBoss Enterprise Application Platform is the market-leading platform for innovative and scalable Java applications. JBoss Enterprise Application Platform integrates the JBoss Application Server with JBoss Hibernate and JBoss Seam into a complete and simple enterprise solution. JBoss Web Services Native is 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 'server/[configuration]/deploy/' directory, along with all other customized configuration files.
Users of JBoss Enterprise Application Platform 4.2.0.CP09 on Red Hat Enterprise Linux 4 and 5 should upgrade to these updated packages, which correct this issue. The JBoss server process must be restarted for this update to take effect.
SolutionUpdate the affected jbossas, jbossas-4.2.0.GA_CP09-bin and / or jbossas-client packages.
