Did you have a test of my file? I've already read bug #37346 , and got the newest version GD from http://snaps.php.net/ ( Stable 5.2.x-dev Built On: May 08, 2006 06:30 GMT ). But, when I test it with the special file, my server was down.

I test it with all GD version (above 2.0.28). Reproduce code: --------------- $file = 'specialimg.gif'; $im = imagecreatefromgif($file); Expected result: ---------------- the memory ran out, and my web server is down. Actual result: -------------- I put the special gif file on my friend's web, you can download it from http://www.freediscuz.net/specialgif.zip. I think some one can use this bug to attack web server. It's so danger. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=37360&edit=1
