Notice: RedHat RHSA-2016-2604-02 notification concerning resteasy-base vulnerabilities and resolutions regarding possible exploitations.
An update for resteasy-base is now available for Red Hat Enterprise Linux 7

Solution

For details on how to apply this update, which includes the changes described in this advisory, refer to:

https://access.redhat.com/articles/11258

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.
Security Fix(es):
* It was discovered that under certain conditions RESTEasy could be forced to parse a request with SerializableProvider, resulting in deserialization of potentially untrusted data. An attacker could possibly use this flaw to execute arbitrary code with the permissions of the application using RESTEasy. (CVE-2016-7050)
Red Hat would like to thank Mikhail Egorov (Odin) for reporting this issue.
Additional Changes:
