Subject: Question regardin deleting a file in /tmp directory
Date: Fri, 28 Mar 2008 15:23:37 +0000	[thread overview]
Message-ID: <91df29a20803280823i3f259b7emb6504bd08d6461ac@mail.gmail.com> (raw)

Hi,

I have this PHP script (simplificated here), called delete_tmp.php
that basically calls external commands:

<?php

$session_file = '/tmp/sess_89765'

system(''rm -f' . ' ' . $session_file);

?>

delete_tmp.php file is owned by gamito.users

/tmp/sess_89765 file has permissions -rw------ and is owned by gamito.users

My /tmp permissions are rwxrwxrwt and is owned by root.root

I know that the the sticky bit only allows files to be deleted by
their owners, the owner of the directory or by root.

Never the less, i can switch to /tmp directory and delete sess_89765
file as user gamito.

If I run:
$ php delete_tmp.php

as root, it deletes sess_89765 file.

But if I do the same has user gamito, it doesn't delete the file !!!

Ideas ?

Any help would be appreciated.

Warm Regards,
Mário Gamito
