Thanks fo the answer.
But, another example:
--------------------
#!/usr/local/bin/php-5.2 -q
//set group ID to operator
posix_setgid(5);
posix_setegid(5);
//set user ID to nobody
posix_setuid($_uid);
echo 'getuid: ' . posix_getuid() . "\n";
echo 'getgid: ' . posix_getgid() . "\n";
echo 'getegid: ' . posix_getegid() . "\n";
echo file_get_contents('/etc/sudoers');
--------------------
This script returns contents of /etc/sudoers file.
But it shouldn't becouse perms of /etc/sudoers permissions are:
-----
-r--r----- 1 root wheel 1354 Aug 17 2011 /etc/sudoers
----
I'm I right ?
