"From Red Hat Security Advisory 2016:2604 :

An update for resteasy-base is now available for Red Hat Enterprise
Linux 7.

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

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 :

For detailed information on changes in this release, see the Red Hat
Enterprise Linux 7.3 Release Notes linked from the References section."
