Description:
------------
Call ImageCreateFromJPEG crashes web server when provided with invalid image.
In this test scenario http://dl.dropbox.com/u/2807353/phpbugreport.zip image provided is in PNG format. Image size is 300x300x24. My memory_limit = 256M ImageCreateFromJPEG should return FALSE when called with invalid data, instead it crashes web server.

Unhandled exception at 0x7c90108d in httpd.exe: 0xC0000005: Access violation writing location 0x01547104.

Test script:
---------------
<?php

// you can download actual image and script from here: 
// http://dl.dropbox.com/u/2807353/phpbugreport.zip

$moo = ImageCreateFromJPEG('img.jpg');

?>

Expected result:
----------------
ImageCreateFromJPEG() should return FALSE not crash webserver

Actual result:
--------------
Web server crashes

Unhandled exception at 0x7c90108d in httpd.exe: 0xC0000005: Access violation writing location 0x01547104.

Sounds like it happens only with the 5.3 VC6 versions of our builds. Which webserver and SAPI do you use?

For an immediate fix you can use the VC9 version of apache and php. Fetch Apache at http://apachelounge.com.

Applies to PHP 5.3.4 & Apache 2.2.17
Appears critical, especially on virtual hosts.

Use VC9 builds.

PHP: 5.3.3, 5.3.2
Apache: 2.2

imagecreatefromjpeg() crashes apache always, not only with invalid JPEG file.

please provide one image file you use to crash apache then.
