#48104 [NEW]: PHP FD-Leak - FastCGI + auto_prepend
From: james at jamesreno dot com
Operating system: Debian 5.0.1 (lenny); 2.6.26-2-a
PHP version: 5.2.9
PHP Bug Type: Unknown/Other Function
Bug description: PHP FD-Leak - FastCGI + auto_prepend
Description:
------------
PHP leaks file descriptors by not closing the requested file at the end of
request.
See: http://pastebin.com/m3edccacf
*** REGARDLESS of suhosin being enabled/compiled or disable and NOT
patched, the same problem appears. I have removed suhosin from php and yet
the issue still appears. Please dont just "blame suhosin" and ignore this
fact.
No third-party modules are enabled - apc has been disabled & uninstalled
as well.
This seems like an off-by-one somewhere in relation to the auto_prepend.
removing the auto_prepend statement from the php.ini fixes the problem.
Reproduce code:
---------------
Request http://127.0.0.1/somescript.php
auto_prepend_file = "/tmp/test.php";
#/tmp/test.php
<? include("/tmp/test2.php"); ?>
#/tmp/test2.php
<? echo "hello"; ?>
#/var/www/html/somescript.php
echo " world";
Expected result:
----------------
Output of "hello World";
and PHP should close all of its files it opened.
Actual result:
--------------
Output is proper.
PHP opens:
1) /tmp/test.php
2) /tmp/test2.php
3) /var/www/html/somescript.php
however, php only closes:
1) /tmp/test.php
2) /tmp/test2.php
it does NOT close 3) /var/www/html/somescript.php
