Cineform decoder distorts lower 8 pixels on 1080 video

Summary of the bug:
The lower 8 pixels of 1080 height video distorts when decoding Cineform video.
This does not occur when tested against 1088 height so may be related to 1080 not being divisible by 16.
This is also visible when replayed in ffplay.
The same source file does not show the same errors when replayed in Windows Media Player, using the installable GoPro Cineform codecs.
I've been able to see this on multiple clips. All generated from Adobe Premier Pro CC.
How to reproduce:
% ffmpeg -i input.mov -vcodec rawvideo -pix_fmt bgr24 output.mov ffmpeg version N-87327-g18821e3 Copyright (c) 2000-2017 the FFmpeg developers built with gcc 7.2.0 (GCC)
