"From Red Hat Security Advisory 2017:0019 :

An update for gstreamer-plugins-good 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.

GStreamer is a streaming media framework based on graphs of filters
which operate on media data. The gstreamer-plugins-good packages
contain a collection of well-supported plug-ins of good quality and
under the LGPL license.

Security Fix(es) :

* Multiple flaws were discovered in GStreamer's FLC/FLI/FLX media file
format decoding plug-in. A remote attacker could use these flaws to
cause an application using GStreamer to crash or, potentially, execute
arbitrary code with the privileges of the user running the
application. (CVE-2016-9634, CVE-2016-9635, CVE-2016-9636,
CVE-2016-9808)

* An invalid memory read access flaw was found in GStreamer's
FLC/FLI/FLX media file format decoding plug-in. A remote attacker
could use this flaw to cause an application using GStreamer to crash.
(CVE-2016-9807)

Note: This update removes the vulnerable FLC/FLI/FLX plug-in."
