PHP version: 5.2.4
PHP Bug Type: Reproducible crash
Bug description: crash imagecreatefromjpeg specific php 5.2.4
Description:
------------
Imagecreatefromjpeg crash with large-sized pictures (ex 2 Megapixel 500KB)
since php version 5.2.1. The probleme exists width php 5.2.3, 5.2.4 there,
but did not exist php 5.2.0 there.
The increase of memory allowed for php scripts do not solve the problem.
If 8M memory is enough for a picture of 6 Megapixel width php 5.2.0, even
32M of memory is not enough for PHP 5.2.4 , because memory occupation of
the server becomes then very very important(my server has only 2 GB DDR)
The problem declared itself during the upgrade 5.2.1. It is thus necessary
to see what took place during the programming of 5.2.1
Reproduce code:
---------------
$conf = $_GET["conf"];
$fichier = $_GET["fichier"] ;
include("sys/".$conf.".php");
$image = ImageCreateFromJPEG($fichier) ;
$width = imagesx($image) ;
$height = imagesy($image) ;
$ratio = $width / $height ;
$new_width = $widthThumb ;
$new_height = $widthThumb / $ratio ;
if ($new_height > $heightThumb)
{
$new_height = $heightThumb ;
$new_width = $heightThumb * $ratio ;
}
$thumb = imagecreatetruecolor($new_width,$new_height) ;
imagecopyresampled($thumb,$image,0,0,0,0,$new_width,$new_height,$width,$height)
;
header("Content-type:image/jpeg") ;
imagejpeg($thumb) ;
imagedestroy($image) ;
imagedestroy($thumb) ;
Expected result:
----------------
This script work normally with the large-sized pictures of several
megapixels from the new digital cameras
Actual result:
--------------
crash with large-sized pictures
