| <p><code>suexec</code> is used by the Apache HTTP Server to switch |
| to another user before executing CGI programs. In order to achieve this, |
| it must run as <code>root</code>. Since the HTTP daemon normally doesn't |
| run as <code>root</code>, the <code>suexec</code> executable needs the |
| setuid bit set and must be owned by <code>root</code>. It should never be |
| writable for any other person than <code>root</code>.</p> |
| |
| <p>For further information about the concepts and and the security model |
| of suexec please refer to the suexec documentation (<a href="http://httpd.apache.org/docs/2.0/suexec.html">http://httpd.apache.org/docs/2.0/suexec.html</a>).</p> |
