Hi, I came across myself with a problem... Using phpsuexec disabled, know problems is visible, as users reading other owned php files, etc. But, you can disabled resource as not allow users to change safe_mode even using php_admin_value or php_flag. With phpsuexec enable, many this permissions problems is solved, but others appear! :/ With phpsuexec and a php.ini on directory of php file you can disable safe_mode again and read /etc/passwd files for example. I want to you how I can enable permanently safe_mode and how I can use SUEXEC and PHPSUEXEC with CHROOT, using jailshell for example. So I will do not have hack issues on machine.
