Upgrade Debian:12 tiff to version 4.5.0-6 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:12 relevant fixed versions and status.

A NULL pointer dereference flaw was found in Libtiff's LZWDecode() function in the libtiff/tif_lzw.c file. This flaw allows a local attacker to craft specific input data that can cause the program to dereference a NULL pointer when decompressing a TIFF format file, resulting in a program crash or denial of service.
