Hey folks, I remember when I was still barely out of my teenagehood, people were mostly using ssh/scp while rtools (rsh, rlogin, ... for the youngsters) were left in place as a courtesy for legacy production systems still relying it on them. Fast forward to 2017 (so yes, 15 years later), stack-clash [1] sorely reminds us that suid binaries are an attack surface. I don't even need to mention that it's a healthy engineering practice to remove unused code, both from a maintenance and security perspective. Therefore, I hereby propose to remove rtools from the base system. I acknowledge this will likely cause troubles for a handful of people who are still relying on it for good or bad reasons. But the flipside is that the attack surface of millions of FreeBSD installed out there will be reduced. The proposed roadmap is: - disable from the build on head and let it soak for one month - remove rtools from the base. What do you guys think? Any preferred color for the bikeshed? :) [1] https://www.qualys.com/2017/06/19/stack-clash/stack-clash.txt -- Jeremie Le Hen jlh@FreeBSD.org
