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.

The TIFFReadDirEntryArray function in tif_read.c in LibTIFF 4.0.8 mishandles memory allocation for short files, which allows remote attackers to cause a denial of service (allocation failure and application crash) in the TIFFFetchStripThing function in tif_dirread.c during a tiff2pdf invocation.
