Summary

RESTEasy contains a JBoss project that provides frameworks to help build RESTful Web Services and RESTful Java applications. It is a fully certified and portable implementation of the JAX-RS specification.
It was found that the fix for CVE-2012-0818 was incomplete: external parameter entities were not disabled when the resteasy.document.expand.entity.references parameter was set to false. A remote attacker able to send XML requests to a RESTEasy endpoint could use this flaw to read files accessible to the user running the application server, and potentially perform other more advanced XXE attacks. (CVE-2014-3490)
This issue was discovered by David Jorm of Red Hat Product Security.
All resteasy-base users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.
