This was assigned CVE-2017-14857. Can you please report this upstream. Is there a reason why you are fuzzing the trunk/version of exiv2 and you are reporting it to redhat instead of the upstream project? The upstream issue is https://github.com/Exiv2/exiv2/issues/76 (has been fixed). Fixed with exiv2-0.27.0-1.el7_6. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory, and where to find the updated files, follow the link below. If the solution does not work for you, open a new bug report. https://access.redhat.com/errata/RHSA-2019:2101 |
