Thanks for the zip! I will try take a look if there is something obviously wrong in ext/exif.

Ps. I think the reason its fixed in newer versions is due to stas@ security fixes that could have
flipped the coin and actually make them work.

Sorry, they are no longer there. Try https://betatest.opajaap.nl/wp-content/wppa-depot/opajaap/phpbug.zip
this zip contains 5 of them.

FYI: Seems to be fixed in php 7.2.7

Hi, whenever I try to access the linked .jpg's, I get a WP login page, any chance you can share
them in a non protected space or zip them all?

Thanks

Description:
------------
In version 7.2.0 i get very many errors from exif_read_data().

To me it looks very unlikely that so many (but not all) of those .jpg files have corrupt exif data.
A few examples:

Test script:
---------------
// Get exif data
$exif = exif_read_data( $file, 'EXIF' );

// $file contains the full path to a .jpg file.
