PHP Bug Type: Reproducible crash
Bug description: Apache crashing while someone Upload an Image
Description:
------------
I'm hosting a costumer, who uses an old script written for php 3.x.
If at the same time some visitors uploads an image, apache "crashed".
The load average jumps to 50 > an there is no possible to connect to the
server via ssh anymore.
In the error.log i get i.e. the following messages:
[Sat Jan 29 01:35:30 2005] [warn] child process 24784 still did not exit,
sending a SIGTERM
Reproduce code:
---------------
<form ENCTYPE="multipart/form-data" name=info method=post
ACTION="page.upload.php">
<table>
<tr>
<td>Datei:</td>
<td> <INPUT TYPE="hidden" name="MAX_FILE_SIZE" value="100000"><input
name="userfile" type="file" <? echo $styleform3; ?>>
<INPUT TYPE="hidden" NAME="code" value="1"><br>
<INPUT TYPE="hidden" NAME="user" value="<? echo $user;?>"></td>
</tr>
...
if (is_uploaded_file ($userfile)){
$dir = "/var/kunden/webs/web1/tmp/";
move_uploaded_file($userfile,$dir.$userfile_name) ;
}
Expected result:
----------------
When I upload an image, which is more than 100000 bytes big, cause of the
html-code <INPUT TYPE="hidden" name="MAX_FILE_SIZE" value="100000"> it's
given, i get an php error, that the script gets no data.
Apache breaks the transfer to php, cause the image is bigger then 100000
bytes.
Actual result:
--------------
If you delete the hmtl-tag <INPUT TYPE="hidden" name="MAX_FILE_SIZE"
value="100000"> an add in your script a check, written in php, for the
size and may be the type of the file, you won't get an apache "crash".
