Bug #75275 [NEW]: imagecreatefrom Functions Not Failing On Corrupt Images

From: coryldean at gmail dot com Operating system: Linux PHP version: 7.1.9 Package: GD related Bug Type: Bug Bug description:imagecreatefrom Functions Not Failing On Corrupt Images Description: ------------ --- From manual page: http://www.php.net/function.imagecreatefromjpeg --- When running the Test Script on PHP 5.2.17 it return false - as it should - when trying to load a corrupt image. However, on PHP 7.1.9 the Test Script returns a resource as if the image is fine. Test script: --------------- if(!imagecreatefromjpeg($FileSplFileInfo->getRealPath())) { echo 'ERROR - Corrupt Image'; } else { echo 'SHOULD NOT GET HERE!'; } Expected result: ---------------- When passing in a valid path to a corrupt .JPEG file, it should echo the error message. Below is what I get when running the script in PHP 5.2.17 Warning: imagecreatefromjpeg(): gd-jpeg, libjpeg: recoverable error: Premature end of JPEG file in PATH_TO_PHP_FILE_THAT_EXECUTED_CODE on line 491 Warning: imagecreatefromjpeg(): 'PATH_TO_FILE.JPEG' is not a valid JPEG file in PATH_TO_PHP_FILE_THAT_EXECUTED_CODE on line 491 ERROR - Corrupt Image Actual result: -------------- Below is what I get when running the script in PHP 7.1.9 SHOULD NOT GET HERE! -- Edit bug report at https://bugs.php.net/bug.php?id=75275&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=75275&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=75275&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=75275&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=75275&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=75275&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=75275&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=75275&r=needscript Try newer version: https://bugs.php.net/fix.php?id=75275&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=75275&r=support Expected behavior: https://bugs.php.net/fix.php?id=75275&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=75275&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=75275&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=75275&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=75275&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=75275&r=dst IIS Stability: https://bugs.php.net/fix.php?id=75275&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=75275&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=75275&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=75275&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=75275&r=mysqlcfg
