Edit report at https://bugs.php.net/bug.php?id=79687&edit=1 ID: 79687 Patch added by: cmb@php.net Reported by: 7tonin at laposte dot net Summary: Sony picture - PHP Warning - Make, Model, MakerNotes Status: Re-Opened Type: Bug Package: EXIF related Operating System: linux 5.6.14-desktop-2.mga7 x86 PHP Version: 7.3.18 Assigned To: cmb Block user comment: N Private report: N New Comment: The following pull request has been associated: Patch Name: Fix #79687: Sony picture - PHP Warning - Make, Model, MakerNotes On GitHub: https://github.com/php/php-src/pull/5709 Patch: https://github.com/php/php-src/pull/5709.patch Previous Comments: ------------------------------------------------------------------------ [2020-06-12 14:34:41] cmb@php.net > Previous PHP version did succeed in retrieving thumbnailImage > from Exif. Can we call that a regression ? Indeed. I had solely focused on exif_read_data(), but ignored that extracting the thumbnail fails. ------------------------------------------------------------------------ [2020-06-12 12:36:34] 7tonin at laposte dot net I understand PHP is not supposed to solve problems potentially dropped by image editors. This picture seems cropped before I had received it. Previous PHP version did succeed in retrieving thumbnailImage from Exif. Can we call that a regression ? On my webserver, with the warning comes the modification of file rights to apache:apache (owner:group). I suspect httpd more than PHP, or maybe a secure layer behaviour. Anyway, the workaround is easy. ------------------------------------------------------------------------ [2020-06-12 07:32:00] cmb@php.net Thanks for sending the image by mail! I can confirm the reported behavior, but I cannot see why that would be a bug. The PHP warning for the unmodified image correlates to exiftool's: Warning : Bad MakerNotes directory ------------------------------------------------------------------------ [2020-06-11 12:53:23] cmb@php.net Could you please make the image file available somewhere else for download? ------------------------------------------------------------------------ [2020-06-11 09:39:24] 7tonin at laposte dot net exif_read_data function is also impacted ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
