From Red Hat Security Advisory 2016:2597 :

An update for firewalld is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Moderate. 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.

firewalld is a firewall service daemon that provides a dynamic customizable firewall with a D-Bus interface.

The following packages have been upgraded to a newer upstream version:
firewalld (0.4.3.2). (BZ#1302802)

Security Fix(es) :

* A flaw was found in the way firewalld allowed certain firewall configurations to be modified by unauthenticated users. Any locally logged in user could use this flaw to tamper or change firewall settings. (CVE-2016-5410)

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.

The remote host is affected by the vulnerability described in GLSA-201701-70 (Firewalld: Improper authentication methods)

    A flaw in Firewalld allows any locally logged in user to tamper with or       change firewall settings.  This is due to how Firewalld handles       authentication via polkit which is not properly applied to 5 particular       functions to include: addPassthrough, removePassthrough, addEntry,       removeEntry, and setEntries.
  Impact :

    A local attacker could tamper or change firewall settings leading to the       additional exposure of systems to include unauthorized remote access.
  Workaround :

    There is no known workaround at this time.
