I thought it is #6741 but the messages in the console are different. The two images in p7 and 8 are big, but not THAT big.

Is there any solution for this yet?

I'm not part of this project, I just hang around and look at problem PDFs. #6741 does not have a solution yet, obviously. And as I wrote, it isn't sure that this is the cause.

Pages 7 and 8 contains corrupt JPEG images, which have SOF (Start of Frame) markers with completely incorrect scanLines parameters, see excerpt below:

ffc0 0011 08ff 0028 0803 0122 0002 1101 0311 01..

As outlined in the JPEG specification, see https://www.w3.org/Graphics/JPEG/itu-t81.pdf#page=40, the scanLines value here is 0xff 0x00 => 65280 whereas the correct value would be 3712.

Trying to fix this will, most likely, require adding a fair bit of heuristics but is probably doable (although it probably won't be fast, since we'll have to parse the image twice in order to recover).
