Notes
- exiv2 <not-affected> (Vulnerable code introduced after 0.25; only affected experimental; bug #868578)
https://github.com/Exiv2/exiv2/issues/50
https://bugzilla.redhat.com/show_bug.cgi?id=1470737
Not reproducible in wheezy/jessie/stretch (even with valgrind), I get "No Exif data found in the file".
Reproducible with 0.26-1 (experimental).
Action::TaskFactory::cleanup function is the same in all versions, so the problem is likely an earlier memory corruption.
