How to fix?

Upgrade Debian:9 libexif to version 0.6.19-1 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.

Heap-based buffer overflow in the exif_entry_fix function (aka the tag fixup routine) in libexif/exif-entry.c in libexif 0.6.18 allows remote attackers to cause a denial of service or possibly execute arbitrary code via an invalid EXIF image. NOTE: some of these details are obtained from third party information.
