How to fix?

Upgrade Debian:10 tiff to version 4.1.0+git191117-2~deb10u4 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.

Null source pointer passed as an argument to memcpy() function within TIFFReadDirectory() in tif_dirread.c in libtiff versions from 4.0 to 4.3.0 could lead to Denial of Service via crafted TIFF file. For users that compile libtiff from sources, a fix is available with commit 561599c.
