How to fix?

Upgrade Debian:9 libexif to version 0.6.20-3 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libexif package and not the libexif package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

The mnote_olympus_entry_get_value function in olympus/mnote-olympus-entry.c in the EXIF Tag Parsing Library (aka libexif) before 0.6.21 allows remote attackers to cause a denial of service (divide-by-zero error) via an image with crafted EXIF tags that are not properly handled during the formatting of EXIF maker note tags.
