gstreamer security update

CentOS Errata and Security Advisory CESA-2017:0018

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

• A memory corruption flaw was found in GStreamer’s Nintendo NSF music 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-2016-9447)

• An out-of-bounds heap read flaw was found in GStreamer’s H.264 parser. A remote attacker could use this flaw to cause an application using GStreamer to crash. (CVE-2016-9809)

Note: This update removes the vulnerable Nintendo NSF plug-in.
