"An update for gstreamer1-plugins-bad-free 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 gstreamer1-plugins-bad-free package
contains a collection of plug-ins for GStreamer.

Security Fix(es) :

* An integer overflow flaw, leading to a heap-based buffer overflow,
was found in GStreamer's VMware VMnc video file format decoding
plug-in. A remote attacker could use this flaw to cause an application
using GStreamer to crash or, potentially, execute arbitrary code with
the privileges of the user running the application. (CVE-2016-9445)

* Multiple flaws were discovered in GStreamer's H.264 and MPEG-TS
plug-ins. A remote attacker could use these flaws to cause an
application using GStreamer to crash. (CVE-2016-9809, CVE-2016-9812,
CVE-2016-9813)

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.");
