wsf/common/DOMUtils.java in JBossWS Native in Red Hat JBoss Enterprise Application Platform 4.2.0.CP09, 4.3, and 5.1.1; JBoss Enterprise Portal Platform 4.3.CP06 and 5.1.1; JBoss Enterprise SOA Platform 4.2.CP05, 4.3.CP05, and 5.1.0; JBoss Communications Platform 1.2.11 and 5.1.1; JBoss Enterprise BRMS Platform 5.1.0; and JBoss Enterprise Web Platform 5.1.1 does not properly handle recursion during entity expansion, which allows remote attackers to cause a denial of service (memory and CPU consumption) via a crafted request containing an XML document with a DOCTYPE declaration and a large number of nested entity references, a similar issue to CVE-2003-1564.

The remote Redhat Enterprise Linux 5 / 6 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2011:1303 advisory.

    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.
