sbox is a CGI wrapper script that allows Web site hosting services to safely grant CGI authoring privileges to untrusted clients. In addition to changing the process privileges of client scripts to match their owners, it goes beyond other wrappers by placing configurable ceilings on script resource usage, avoiding unintentional (as well as intentional) denial of service attacks. It also optionally allows the Webmaster to place client's CGI scripts in a chroot'ed shell restricted to the author's home directories. sbox is compatible with all Web servers running under BSD-derived flavors of Unix. You can use and redistribute it freely. WWW: http://www.gplhost.com/software-sboxdtc.html
