How to fix?

Upgrade Debian:10 tiff to version 4.0.10-4 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:10 relevant fixed versions and status.

In LibTIFF 4.0.9, there is a NULL pointer dereference in the TIFFWriteDirectorySec function in tif_dirwrite.c that will lead to a denial of service attack, as demonstrated by tiffset.
