Bug #71093 [NEW]: GD: Very high memory consumption with bundled library 2.1.0

From: jeep dot gaudreau at gmail dot com Operating system: Fedora 23 PHP version: 5.6.16 Package: GD related Bug Type: Bug Bug description:GD: Very high memory consumption with bundled library 2.1.0 Description: ------------ I found out that the GD library bundled with PHP 5.6.16 (version 2.1.0) is using a lot of memory when calling functions "imagecreatefromjpeg" or "imagecreatefromstring" on JPEG files. A JPEG file of about 4MB can generate up to 300MB of memory while it take not more than a few KB when using the OS package of GD version 2.1.1. I can also reproduce the bug on RHEL6.5 Maybe the solution would only be to upgrade the bundled PHP GD library to 2.1.1. Here's the GD info when memory consumption is very high : GD Support enabled GD Version bundled (2.1.0 compatible) FreeType Support enabled FreeType Linkage with freetype FreeType Version 2.6.0 T1Lib Support enabled GIF Read Support enabled GIF Create Support enabled JPEG Support enabled libJPEG Version 6b PNG Support enabled libPNG Version 1.6.19 WBMP Support enabled XPM Support enabled libXpm Version 30411 XBM Support enabled WebP Support enabled GD Support enabled Here's the GD info when memory consumption is low : GD headers Version 2.1.1 GD library Version 2.1.1 FreeType Support enabled FreeType Linkage with freetype FreeType Version 2.6.0 T1Lib Support enabled GIF Read Support enabled GIF Create Support enabled JPEG Support enabled libJPEG Version 6b PNG Support enabled libPNG Version 1.6.19 WBMP Support enabled XPM Support enabled libXpm Version 30411 XBM Support enabled WebP Support enabled Test script: --------------- Very easy to reproduce: * Create the following PHP script: <?php $path = 'img.jpg'; //$image = imagecreatefromjpeg($path); $image = imagecreatefromstring(file_get_contents($path)); var_dump(memory_get_usage()); * Execute with the following JPEG image: https://drive.google.com/open?id=0B0H8CbGn160eMHg3cGZrSmtzRTA You should have very high memory usage with bundled library 2.1.0 You should have very low memory usage with OS package GD version 2.1.1 -- Edit bug report at https://bugs.php.net/bug.php?id=71093&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=71093&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=71093&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=71093&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=71093&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=71093&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=71093&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=71093&r=needscript Try newer version: https://bugs.php.net/fix.php?id=71093&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=71093&r=support Expected behavior: https://bugs.php.net/fix.php?id=71093&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=71093&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=71093&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=71093&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=71093&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=71093&r=dst IIS Stability: https://bugs.php.net/fix.php?id=71093&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=71093&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=71093&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=71093&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=71093&r=mysqlcfg
