Bug #931496 has been fixed in simple-scan 3.3.92 Hopefully that version fixes the problems described here as well. Please report back whether or not you can reproduce the problem with simple-scan 3.3.92 or later.

Normally also affected by this very same bug, I just got the following abort in glibc while saving a larger (several pages) scanned document.

Added the attached printfs.

Aborted (core dumped) This is a buffer overrun by one byte. You can see clearly that all the other color depths (besides DeviceGray) add an extra byte to account for this overflow. Only the DeviceGray one does not, adding one to the data_length calculations for DeviceGray fixes the problem.

[Bug 664608] Re: simple-scan crashes when saving to PDF
I think the crashes are related to the scan size format. I only got these crashes when the scan size is set to Automatically instead of A4. When using A4 this does not happen. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/664608 Title: simple-scan crashes when saving to PDF To manage notifications about this bug go to: https://bugs.launchpad.net/simple-scan/+bug/664608/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 664608] Re: simple-scan crashes when saving to PDF
Hi everyone, I brought this bug to Robert Ancell's attention. Good thing: he looked into it. Bad thing: he could not reproduce/debug the issue. Robert believes this happens due to a corrupted adress space, caused by a bad scanner driver running in the same adress space as Simple Scan. I do not think Robert is right, and that maybe some size control information (image size or the like) returned by the scanner is incorrect, but the adress space itself is intact, because a) the pixel data is good enough to be displayed, so it should be good enough to be saved b) there are not random crashes, but it happens deterministically when saving a PDF So, to see who is right we need the following: - A description in your own words what exacly you do to recreate (not: me too) and if it happens in 100% of the cases or just sometimes/most of the times/rarely/... - Make, Model and ID (as listed by lsusb) of the scanner - An apport report might be useful. Enable apport: https://wiki.ubuntu.com/Apport then make the problem happen and report the issue via apport. Include make, model and id in the description and CLEARLY STATE that is a reproduction of this bug, #664608 You might need to change the issue from private to public visibility so we can see it. - If someone who can recreate -- and has the necessary skills -- could poke around a bit with gdb that might help...
