> We had a PDF that had a strange page with 200Mb+ of text to extract and the
> deflate function did not work correctly.
> This created a fatal in PDFBox and I did some debugging and noticed that we
> handle SetNonStrokingColorSpace and SetStrokingColorSpace in different ways.
> One of them had a check if the in data was incorrect and returned and the
> other one did not have this check.
> I made this small patch that I will include in this issue to rectify this
> inconsistency.
>
> Added the crashing pdf on my google drive if you want it to test with
