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.

Off-by-one error in the exif_convert_utf16_to_utf8 function in exif-entry.c in the EXIF Tag Parsing Library (aka libexif) before 0.6.21 allows remote attackers to cause a denial of service or possibly execute arbitrary code via crafted EXIF tags in an image.
