Affects: fedora-all [bug 1691725]

Comment 3 Scott Gayou 2019-03-22 17:44:22 UTC
Red Hat Enterprise Linux 7 poppler (0.26.5) does not appear to be impacted by this stack overflow and completes without segfaulting. Versions before 0.26.5 do not appear impacted as well -- the code is quite different.
