How to fix?

Upgrade Debian:10 tiff to version 4.1.0+git191117-2~deb10u5 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.

libtiff's tiffcrop utility has a uint32_t underflow that can lead to out of bounds read and write. An attacker who supplies a crafted file to tiffcrop (likely via tricking a user to run tiffcrop on it with certain parameters) could cause a crash or in some cases, further exploitation.
