I added a test case for this to php-src: http://git.php.net/?p=php-src.git;a=commit;h=469206c84e502e3e349655b802899d5e4d560f72 Previous Comments: ------------------------------------------------------------------------ [2017-07-08 01:00:44] kalle@php.net Thank you very much Lee, I do some testings with this one! ------------------------------------------------------------------------ [2017-07-07 15:23:54] lee dot traynor at skeptic dot de Try this image: http://www.skeptic.de/blog/kvi/IMG_0001_D.JPG I get: PHP Warning: exif_read_data(IMG_0001_D.JPG): IFD data bad offset: 0xFFFFFCAC length 0x08C8 ------------------------------------------------------------------------ [2017-07-07 10:32:05] kalle@php.net Hi Could you please provide me with a test image? Thanks ------------------------------------------------------------------------ [2016-09-19 15:12:33] lee dot traynor at skeptic dot de Description: ------------ On encountering a binary string in exif data (e.g. makernote) exif_read_data () terminates reading, returns the exif tags successfully read and issues a warning about unreadable data. This does not occur in php <= 5.6.16, where the full set of exif tags is returned without warning. This bug may be related to Bug #72819 EXIF thumbnails not read anymore. Test script: --------------- exif_read_data ("img_0001.jpg"); Expected result: ---------------- All exif tags returned without error. Actual result: -------------- Only exif tags prior to "makernote" (which is a binary string) are returned and a warning issued. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=73115&edit=1
