gstreamer1 security update

CentOS Errata and Security Advisory CESA-2017:0020

GStreamer is a streaming media framework based on graphs of filters which operate on media data. The gstreamer1-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.
