There are many documented code execution opportunities (some of them still rather subtle), so I find any arguments based on the existence of a hypothetical secure procmailrc file generator not very convincing. :0 |echo code execution >/dev/tty :0 * ?echo code execution >/dev/tty /dev/null … and so on. -- Florian Weimer / Red Hat Product Security
