PHP Bug Type: Unknown/Other Function
Bug description: header('Location...') crash
Description:
------------
Due to a mistake, we passed an unusual long String to header(), and the
webserver.
>From /var/log/messages:
Sep 15 15:17:27 www5 kernel: pid 92266 (httpd), uid 80: exited on signal
4
My String contains an urlencode() "SQL error", which I wanted to pass on
to the next page via GET.
The "SQL error" includes the query I issued (including the binary data
that was supposed to be saved to the database) and the error message from
MySQL.
We run Apache2, with PHP as a module.
Reproduce code:
---------------
Unfortunately, I cannot copy and paste it here. It's just too long. The
entire string passed to header() was 79600 characters long.
If needed I can upload it on a URL and add it later on as a comment.
The simple code is:
<?php
$str = 'Location:--really--really--long--string--';
header($str);
exit;
?>
Expected result:
----------------
I know that you are only supposed to send only 256 (?) characters over
GET, but for example I would expect the string to be cut off instead, or
header() to return false.
Actual result:
--------------
Webserver crashed.
