From: camka at email dot ee Operating system: WinXP, Linux PHP version: 5.2.1RC2 PHP Bug Type: EXIF related Bug description: exif_read_data dies on certain images
Description: ------------ PHP dies on certain files format while reading exif data with exif_read_date because of some maximum directory nesting level reached. The function should return FALSE and let the program flow further. Otherwice misformated image processing may kill script and break the program logic. Even if i suppress warnings with @ sign, i still cannot manage to let the program go further after unsuccessfull reading exif data. broken file: http://www.hot.ee/camka/orig.phpJCN9Ir.jpg Tried with 5.1.6, 5.2.0 and latest snapshot of 5.2.1. P.S. All editors successfully show EXIF data for current file, so maybe it's not misformatted exif data but exif extension cannot process some newer exif formats? Reproduce code: --------------- <? $z = exif_read_data('orig.phpJCN9Ir.jpg', 'FILE,COMPUTED,IFD0,EXIF', true, false); var_dump($z); Expected result: ---------------- [...Errors (see below)...] FALSE Actual result: -------------- $ php exif.php PHP Warning: exif_read_data(orig.phpJCN9Ir.jpg): Illegal IFD size: x04F6 + 2 + xFFF1*12 = xC0442 > x16BF in exif.php on line 2 PHP Warning:
