How to fix?

Upgrade Debian:9 tiff to version 4.0.8-2+deb9u2 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.

There is a heap based buffer overflow in tools/tiff2pdf.c of LibTIFF 4.0.8 via a PlanarConfig=Contig image, which causes a more than one hundred bytes out-of-bounds write (related to the ZIPDecode function in tif_zip.c). A crafted input may lead to a remote denial of service attack or an arbitrary code execution attack.
