Description:
------------
When accessing foreign URLs with getimagesize(), apache server crashes with:

szAppName : Apache.exe     szAppVer : 2.0.55.0     szModName : php4ts.dll     
szModVer : 4.4.2.2     offset : 000c5fca

---------------------
The only changes made to the PHP.ini file were the enabling/removing the comment in front of the GD2 and the ZIP, DLL extensions.

Server is running as a test environment on localhost.

Reproduce code:
---------------
<?php
getimagesize('images/example.gif');  //Works Fine (Local)
getimagesize('example.jpg'); //Works Fine
//The following crash the Entire Apache server, no matter where they're used
getimagesize('http://example.com/example/example.jpg');//Crashes 
getimagesize('http://example.com/example.jpg'); //Crashes 
getimagesize('http://example.com/example.gif'); //Crashes
@getimagesize('http://example.com/example.gif'); //Crashes
?>

Expected result:
----------------
Apache 2 Servers lags for a slight moment, then crashes 100% of the time that a page using a foreign URL call to getimagesize() is run.

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php for *NIX and
http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32

Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.

Works fine here.

I would love to help, however those instructions aren't detailed enough for me to do anything.  I need to know the exact files I need and where to put them.  I'm sorry, I'm not that smart. :(

Please try using this CVS snapshot:

  http://snaps.php.net/php5.1-latest.tar.gz
 
For Windows:

I have had a similar problem with IIS and php.exe:

With external urls getimagesize causes an indefinite loop in that function.

Using the isapi module php4isapi.dll solves the problem.

This also happens with Apache 1.3.33 and 2.0.54 consistently with 4.4.2 on Windows 2000.  Will try to get a backtrack but given where and when it's crashing it may not work.

I can confirm that this problem is fixed with 5.1.2.  I didn't see a backtrace version for 4.4.2 so was unable to get one.  But something is certainly broken in 4.4.2.

I am getting the same error without Apache environment when using function file_get_contents() and file() with http protocol... I think it is connected
 [2006-03-16 15:07 UTC] jaroslav dot povolny at gmail dot com 
I have just installed back 4.4.1 version and the bug disappeared. It is definetelly 4.4.2 bug, it is somewhere in file() or file_get_contents(). Platform: Windows XP
 [2006-04-05 02:57 UTC] nospam at fidk dot com 
Get the same problem (PHP crashes) with fopen as well as file and file_get_contents.  Under 4.2.2.  Try this code:

<?php
    $host = 'weather.aero';
    $location =   "/dataserver0_9/httpparam?dataSource=airsigmets&requestType=retrieve&format=xml&minLat=25&minLon=-130&maxLat=65&maxLon=-40&hoursBeforeNow=3";


   $pirepUrl = "http://".$host.$location;
   $fd = fopen($pirepUrl, "rb");

   echo("Done");


?>

This bug has been fixed in CVS 3 months ago.

I have the same problem! even though there is sentence at the bottom of this page which claims the problem has been solved! I PHP 5.2.8 and Apache 2! as soon as I deactivate the part of code which uses the get_image_size function everything's ok! but if I let it run, Apaches crash and MySQL returns hundreds of Null Sleep State queries because it can not connect to Apache!
I wanna know what PHP & Apache version support the function with out problem?

P.S: unfortunately due to Apache crash, the log file doesn't return any error..
 [2010-07-07 08:18 UTC] nooshin dot ha at gmail dot com 
well, I think I solved the problem by myself! we defined a sub domain for our images (e.g images.example.com) and we address the images to the function with this url-base method! I changed it to directory-base like this "/images/"and it works fine!!! however I used linux server ...

Open a new bug using the image crashing imagegetsize (provide a link to it). Also please try using the latest PHP or RC before.
