Comment 1 Laura Pardo 2018-04-12 17:42:15 EDT 
Created exiv2 tracking bugs for this issue:

Affects: fedora-all [bug 1566727]
Comment 3 Riccardo Schirone 2018-04-18 07:55:39 EDT 
Statement:

This issue did not affect the versions of Exiv2 as shipped with Red Hat Enterprise Linux 6 and 7 as they did not include support for BigTIFF images.
