DESCRIPTIONThis collection of modules started out as modules which perform things (debatably) in a safer and taint-safe manner. Since then it's also grown to include functionality that fit into the same framework and conventions of the original modules, including keeping the debug hooks for command-line debugging.
All the modules below are intended to be used directly in your programs if you need the functionality they provide.
This module does provide one function meant to secure your environment enough to satisfy taint-enabled programs, and as a container which holds the last reported error from any code in the Paranoid framework.
This function deletes some of the dangerous environment variables that can be used to subvert perl when being run in setuid applications. It also sets the path, either to the passed argument (if passed) or a default of ``/bin:/usr/bin''.
$errMsg = Paranoid::ERROR; Paranoid::ERROR = $errMsg;
This lvalue function is not exported and must be referenced via the Paranoid namespace.
TAINT NOTESTaint-mode programming can be somewhat of an adventure until you know all the places considered dangerous under perl's taint mode. The following functions should generally have their arguments detainted before using:
exec system open glob unlink mkdir chdir rmdir chown chmod umask utime link symlink kill eval truncate ioctl fcntl chroot setpgrp setpriority syscall socket socketpair bind connect
