"From Red Hat Security Advisory 2017:2486 :

An update for groovy 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.

Groovy is an agile and dynamic language for the Java Virtual Machine,
built upon Java with features inspired by languages like Python, Ruby,
and Smalltalk. It seamlessly integrates with all existing Java objects
and libraries and compiles straight to Java bytecode so you can use it
anywhere you can use Java.

Security Fix(es) :

* It was found that a flaw in Apache groovy library allows remote code
execution wherever deserialization occurs in the application. It is
possible for an attacker to craft a special serialized object that
will execute code directly when deserialized. All applications which
rely on serialization and do not isolate the code which deserializes
objects are subject to this vulnerability. (CVE-2016-6814)"
