How to fix?

Upgrade Debian:11 tiff to version 4.2.0-1+deb11u3 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:11. See How to fix? for Debian:11 relevant fixed versions and status.

libtiff's tiffcrop tool has a uint32_t underflow which leads to out of bounds read and write in the extractContigSamples8bits routine. An attacker who supplies a crafted file to tiffcrop could trigger this flaw, most likely by tricking a user into opening the crafted file with tiffcrop. Triggering this flaw could cause a crash or potentially further exploitation.
