gst-ffmpeg: fixes for CVE-2014-8548 and CVE-2014-8541

Issue: LIN7-1755
Issue: LIN7-1739

http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2014-8541

libavcodec/mjpegdec.c in FFmpeg before 2.4.2 considers only dimension
differences, and not bits-per-pixel differences, when determining whether an
image size has changed, which allows remote attackers to cause a denial of
service (out-of-bounds access) or possibly have unspecified other impact via
crafted MJPEG data.

Off-by-one error in libavcodec/smc.c in FFmpeg before 2.4.2 allows remote
attackers to cause a denial of service (out-of-bounds access) or possibly
have unspecified other impact via crafted Quicktime Graphics (aka SMC) video
data.
