WHAT IS IT ?

noexec - package for preventing process(es) from executing exec system call


WHERE IT CAN BE USEFULL ?

1) You provide user with some kind of menu to allow him to run only
   specific program, and you want to disable possible escape to shell
   from these programs.

2) sudo configuration.
   It was my first goal, but really sudo configuration 
   is a kind of menu

3) I think it can be usefull in preventing some kinds of exploiting
   CGI scripts. 


HOW IT WORKS ?

It's a trivial - my exec* functions simple set errno to EACCES and return -1;


USAGE.

Just set following environment variables:

LD_PRELOAD - to the libnoexec.so location


Or you can write in the /etc/sudoers somethin like this:
user ALL = /usr/bin/noexec /usr/bin/less /etc/shadow 

It will allow to user 'user' look to the /etc/shadow with less and
without option escape to the shell.
