Created exiv2 tracking bugs for this issue:

Affects: fedora-all [bug 1561214]

Comment 6 Pedro Yóssis Silva Barbosa 2018-04-06 18:38:08 EDT

This issue does not affect the exiv2 version shipped in Red Hat Enterprise Linux 7.4. However, in Red Hat Enterprise Linux 7.5, exiv2 is rebased to the affected version (0.26).
