gst-ffmpeg: fix CVE-2013-3674

The cdg_decode_frame function in cdgraphics.c in libavcodec in FFmpeg before
1.2.1 does not validate the presence of non-header data in a buffer, which
allows remote attackers to cause a denial of service (out-of-bounds array
access and application crash) via crafted CD Graphics Video data.
