There is an invalid free in the Action::TaskFactory::cleanup function of actions.cpp in Exiv2 0.26. A crafted input will lead to a remote denial of service attack.

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.
