Comment 1 Andrej Nemec 2016-01-25 15:33:16 UTC
Created libtiff tracking bugs for this issue:

Affects: fedora-all [bug 1301650]

Comment 2 Stefan Cornelius 2016-01-26 12:23:43 UTC
On RHEL5, 6, 7, and Fedora, libtiff is compiled with assertions enabled. Thus, the impact of these flaws is limited to triggering an assertion.
