   Does POSIX_setuid have access to files owned by root?

   • When you do a posix_setuid from root to some other users you will not have access to files owned by root according to their permissions. For instance if you change owner of the process and still need to open a file for read or write with 600 permission owned by root you will receive a permission denied.

   How do I run a PHP script setuid?

   • Here's some Perl code to run a PHP script setuid. Just put it into a CGI, make that CGI setuid and executable, then call the CGI where you would usually call the PHP script. For simple operations, you can easily create a privilege-separation mechanism to perform commands that require elevated privileges.

   Should I use execl() instead of system() in a setuid program?

   • In response to a note above that advocated the user of system () in a setuid program written in C, this is generally a bad idea for security.
