I just finished a blog post detailing how the popular text editor, nano, is unsafe to run as root to edit untrusted users' files, with consequences including full privilege escalation: http://drosenbe.blogspot.com/2010/03/nano-as-root.html This is not a disclosure of vulnerabilities per se; rather, it's just a look at how some security assumptions may not hold when running programs as root in a hostile environment, using nano as an example. Nothing earth-shattering, just thought some of you might be interested. Comments welcome. -Dan
