Bug #75785 [NEW]: Many errors from exif_read_data

From: opajaap at opajaap dot nl Operating system: unknown PHP version: 7.2.1 Package: EXIF related Bug Type: Bug Bug description:Many errors from exif_read_data 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: 09.01.2018 11:37:06 2013.opajaap.nl [client 213.10.98.0] PHP Warning: exif_read_data(42996.jpg): corrupt EXIF header: maximum directory nesting level reached in /mnt/web208/b3/15/51893315/htdocs/opajaap/2013/wp-content/plugins/wp-photo-album-plus/wppa-maintenance.php on line 1479, referer: https://2013.opajaap.nl/wp-admin/admin.php?page=wppa_options 09.01.2018 11:37:28 2013.opajaap.nl [client 213.10.98.0] PHP Warning: exif_read_data(43168.jpg): Illegal IFD size: 2 + 0x2000*12 = 0x18002 > 0xA650 in /mnt/web208/b3/15/51893315/htdocs/opajaap/2013/wp-content/plugins/wp-photo-album-plus/wppa-maintenance.php on line 1479, referer: https://2013.opajaap.nl/wp-admin/admin.php?page=wppa_options 09.01.2018 11:37:35 2013.opajaap.nl [client 213.10.98.0] PHP Warning: exif_read_data(43186.jpg): Illegal IFD size: 2 + 0x0A00*12 = 0x7802 > 0x0C00 in /mnt/web208/b3/15/51893315/htdocs/opajaap/2013/wp-content/plugins/wp-photo-album-plus/wppa-maintenance.php on line 1479, referer: https://2013.opajaap.nl/wp-admin/admin.php?page=wppa_options 09.01.2018 11:37:42 2013.opajaap.nl [client 213.10.98.0] PHP Warning: exif_read_data(43279.jpg): Process tag(x0000=UndefinedTa): Illegal format code 0x0000, suppose BYTE in /mnt/web208/b3/15/51893315/htdocs/opajaap/2013/wp-content/plugins/wp-photo-album-plus/wppa-maintenance.php on line 1479, referer: https://2013.opajaap.nl/wp-admin/admin.php?page=wppa_options 09.01.2018 11:37:42 2013.opajaap.nl [client 213.10.98.0] PHP Warning: exif_read_data(43279.jpg): Process tag(x0000=UndefinedTa): Illegal components(0) in /mnt/web208/b3/15/51893315/htdocs/opajaap/2013/wp-content/plugins/wp-photo-album-plus/wppa-maintenance.php on line 1479, referer: https://2013.opajaap.nl/wp-admin/admin.php?page=wppa_options 09.01.2018 11:37:49 2013.opajaap.nl [client 213.10.98.0] PHP Warning: exif_read_data(43303.jpg): Process tag(x0211=YCbCrCoeffi): Illegal components(0) in /mnt/web208/b3/15/51893315/htdocs/opajaap/2013/wp-content/plugins/wp-photo-album-plus/wppa-maintenance.php on line 1479, referer: https://2013.opajaap.nl/wp-admin/admin.php?page=wppa_options 09.01.2018 11:37:56 2013.opajaap.nl [client 213.10.98.0] PHP Warning: exif_read_data(43355.jpg): Illegal IFD size: 2 + 0x4F00*12 = 0x3B402 > 0x1C7C in /mnt/web208/b3/15/51893315/htdocs/opajaap/2013/wp-content/plugins/wp-photo-album-plus/wppa-maintenance.php on line 1479, referer: https://2013.opajaap.nl/wp-admin/admin.php?page=wppa_options 09.01.2018 11:37:56 2013.opajaap.nl [client 213.10.98.0] PHP Warning: exif_read_data(43356.jpg): Illegal IFD size: 2 + 0x4F00*12 = 0x3B402 > 0x1C7C in /mnt/web208/b3/15/51893315/htdocs/opajaap/2013/wp-content/plugins/wp-photo-album-plus/wppa-maintenance.php on line 1479, referer: https://2013.opajaap.nl/wp-admin/admin.php?page=wppa_options 09.01.2018 11:37:56 2013.opajaap.nl [client 213.10.98.0] PHP Warning: exif_read_data(43357.jpg): Illegal IFD size: 2 + 0x4F00*12 = 0x3B402 > 0x1C7C in /mnt/web208/b3/15/51893315/htdocs/opajaap/2013/wp-content/plugins/wp-photo-album-plus/wppa-maintenance.php on line 1479, referer: https://2013.opajaap.nl/wp-admin/admin.php?page=wppa_options 09.01.2018 11:37:56 2013.opajaap.nl [client 213.10.98.0] PHP Warning: exif_read_data(43358.jpg): Illegal IFD size: 2 + 0x4F00*12 = 0x3B402 > 0x1C7C in /mnt/web208/b3/15/51893315/htdocs/opajaap/2013/wp-content/plugins/wp-photo-album-plus/wppa-maintenance.php on line 1479, referer: https://2013.opajaap.nl/wp-admin/admin.php?page=wppa_options Test script: --------------- // Get exif data $exif = exif_read_data( $file, 'EXIF' );
