Upgrade Debian:9 tiff to version 4.0.8-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream tiff package and not the tiff package as distributed by Debian.
See How to fix? for Debian:9 relevant fixed versions and status.
In LibTIFF 4.0.7, the TIFFReadDirEntryLong8Array function in libtiff/tif_dirread.c mishandles a malloc operation, which allows attackers to cause a denial of service (memory leak within the function _TIFFmalloc in tif_unix.c) via a crafted file.
