Description Laura Pardo 2018-02-14 13:17:49 UTC 
A flaw was found in Exiv2 from commit 307faae8304d. When the library is
compiled in Debug mode, there is a reachable assertion in the readHeader
function in bigtiffimage.cpp, which will lead to a crash via a crafted BigTIFF
file.

Comment 1 Laura Pardo 2018-02-14 13:18:27 UTC 
Created exiv2 tracking bugs for this issue:

Affects: fedora-all [bug 1545247]
Comment 4 Riccardo Schirone 2018-02-21 15:44:02 UTC 
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.
