Description

This digiKam crash happens in exiv2:

http://bugs.kde.org/show_bug.cgi?id=144574

At first glance it seems to be caused by the Makernote of the SONY MVC-CD500 images. It's not clear from the digiKam bug report whether the images come straight from the camera or were processed with other software.

History

Updated by Aaron D Campbell 1051 days ago

I uploaded the three images I have that cause the problem. I have other pictures from that camera that work fine. Would it be helpful to have a couple of those? Also, I do not believe the images were processed with any other software, but I can't guarantee that (May 2004 seems like so long ago).

Thanks. The images which cause the problem should be sufficient. I'll try to find some time to look into this over the weekend.

r1106 fixes the problem in the JPEG parser.
A similar fix for the new TIFF parser is required as well.
