-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: resteasy security update Advisory ID: RHSA-2012:1058-01 Product: JBoss Enterprise Web Platform Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-1058.html Issue date: 2012-07-05 CVE Names: CVE-2012-0818 ===================================================================== 1. Summary: Updated resteasy packages that fix one security issue are now available for JBoss Enterprise Web Platform 5.1.2 for Red Hat Enterprise Linux 4, 5, and 6. The Red Hat Security Response Team has rated this update as having moderate 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. 2. Relevant releases/architectures: JBoss Enterprise Web Platform 5 for RHEL 4 AS - noarch JBoss Enterprise Web Platform 5 for RHEL 4 ES - noarch JBoss Enterprise Web Platform 5 for RHEL 5 Server - noarch JBoss Enterprise Web Platform 5 for RHEL 6 Server - noarch 3. Description: RESTEasy provides various frameworks to help you build RESTful web services and RESTful Java applications. It was found that RESTEasy was vulnerable to XML External Entity (XXE) attacks. If a remote attacker submitted a request containing an external XML entity to a RESTEasy endpoint, the entity would be resolved, allowing the attacker to read files accessible to the user running the application server. This flaw affected DOM (Document Object Model) Document and JAXB (Java Architecture for XML Binding) input. (CVE-2012-0818) Note: The fix for CVE-2012-0818 is not enabled by default. This update adds a new configuration option to disable entity expansion in RESTEasy. If applications on your server expose RESTEasy XML endpoints, a resteasy.document.expand.entity.references configuration snippet must be added to their web.xml file to disable entity expansion in RESTEasy. Refer to Red Hat Bugzilla bug 785631 for details. Warning: Before applying this update, back up your JBoss Enterprise Web Platform's "jboss-as-web/server/[PROFILE]/deploy/" directory and any other customized configuration files. Users of JBoss Enterprise Web Platform 5.1.2 on Red Hat Enterprise Linux 4, 5, and 6 should upgrade to these updated packages, which correct this issue. The JBoss server process must be restarted for this update to take effect. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258 5.
