Description

Red Hat JBoss Enterprise Application Platform 6 is a platform for Java applications based on JBoss Application Server 7.

It was found that the ParserPool and Decrypter classes in the OpenSAML Java implementation resolved external entities, permitting XML External Entity (XXE) attacks. A remote attacker could use this flaw to read files accessible to the user running the application server, and potentially perform other more advanced XXE attacks. (CVE-2013-6440)

It was discovered that the Apache Santuario XML Security for Java project allowed Document Type Definitions (DTDs) to be processed when applying Transforms even when secure validation was enabled. A remote attacker could use this flaw to exhaust all available memory on the system, causing a denial of service. (CVE-2013-4517)

In Red Hat JBoss Enterprise Application Platform, when running under a security manager, it was possible for deployed code to get access to the Modular Service Container (MSC) service registry without any permission checks. This could allow malicious deployments to modify the internal state of the server in various ways. (CVE-2014-0018)

The CVE-2013-6440 was discovered by David Illsley, Ron Gutierrez of Gotham Digital Science, and David Jorm of the Red Hat Security Response Team, and the CVE-2014-0018 issue was discovered by Stuart Douglas of Red Hat.

This release serves as a replacement for JBoss Enterprise Application Platform 6.2.0, and includes bug fixes and enhancements. Documentation for these changes will be available shortly from the JBoss Enterprise Application Platform 6.2.1 Release Notes, linked to in the References.

All users of Red Hat JBoss Enterprise Application Platform 6.2.0 as provided from the Red Hat Customer Portal are advised to apply this update. The JBoss server process must be restarted for the update to take effect.
