CVS.

I'm a chinese user, and I give thousands of students websites with PHP-enabled within 
ONE machine. I found that:

There ARE some security holes in multiuser environment for PHP concerning file system 
functions and directory funtions:

1.file-system functions such as 'fopen' are restricted by 'safe mode' and 
'open_basedir', but 'copy' only checks the 'source' argument, not the 'destination', 
so one can copy his own scripts to someone else' directory and bypass the 
'open_basedir' restriction.

2.'dir' class is not restricted by 'safe mode' or 'open_basedir'!!!

3.'chdir' is dangerous. one user can 'chdir' to another user's directory and access 
the files.
