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.

Integer underflow in the exif_entry_get_value function in exif-entry.c in the EXIF Tag Parsing Library (aka libexif) 0.6.20 might allow remote attackers to execute arbitrary code via vectors involving a crafted buffer-size parameter during the formatting of an EXIF tag, leading to a heap-based buffer overflow.
