"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.

Note that Tenable Network Security has attempted to extract the
preceding description block directly from the corresponding Red Hat
security advisory. Virtuozzo provides no description for VZLSA
advisories. Tenable has attempted to automatically clean and format
it as much as possible without introducing additional issues.");
