Description
libswscale/swscale_unscaled.c in FFmpeg before 2.8.6 does not validate certain height values, which allows remote attackers to cause a denial of service (out-of-bounds array read access) or possibly have unspecified other impact via a crafted .cine file, related to the bayer_to_rgb24_wrapper and bayer_to_yv12_wrapper functions.
