Specific Thumbnail generation for TIF file not working anymore
Open, Needs TriagePublic

Description

Since an unknown date, the thumbnail generation for an .tif file on Commons is no longer working. The file:
https://commons.wikimedia.org/wiki/File:Tessie_Reynolds_02.tif
It was working at least 1.5 years ago when I was editing the file description. The file is still in use in the german article. Currently the usage in enWP has been replaced with its JPG equivalent:
https://commons.wikimedia.org/wiki/File:Tessie_Reynolds_02.jpg

It should be checked if only the file is broken (works with an image viewer under Windows) or if there could be other files affected.

Downloading https://upload.wikimedia.org/wikipedia/commons/7/7e/Tessie_Reynolds_02.tif and using libtiff-4.0.10 to run tiffinfo -D Tessie_Reynolds_02.tif, I get:

TIFFFetchDirectory: Can not read TIFF directory count.
TIFFReadCustomDirectory: Failed to read custom directory at offset 4048276.

Successfully opening the file with gimp-2.10.8 I get a warning:

** (file-tiff:10145): CRITICAL **: 18:06:03.085: Directory Image, entry 0x8769 Sub-IFD pointer 0 is out of bounds; ignoring it.

Is it same issue?
