"A use-after-free vulnerability was found in the Matroska plugin of the
the GStreamer media framework, which may result in denial of service
or potentially the execution of arbitrary code if a malformed media
file is opened.

For Debian 9 stretch, this problem has been fixed in version
1.10.4-1+deb9u1.

We recommend that you upgrade your gst-plugins-good1.0 packages.
