Ok, understand CVE-2017-14733.

Images can declare ncolor channels==1 (greyscale only) or ==2 (makes no

Trouble is, when alpha channel present and we are processing this, we
assume we have at least 3 bytes per pixel: RGB, which just isn't going
to work.

At least that is my understanding reading the code.

Will make fix for this also.
