EvolvisForge blog: PSA: #shellshock still unfixed except in Debian unstable

Planet Debian - Wed, 08/10/2014 - 15:57

I just installed, for work, Hanno Böck’s bashcheck utility on our monitoring system, and watched all¹ systems go blue.

① All but two. One is not executing remote scripts from the monitoring for security reasons, the other is my desktop which runs Debian “sid” (unstable).

This means that all those distributions still have unfixed #shellshock bugs.

I don’t know if/when all distributions will have patched their packages ☹ but thought you’d want to know the hysteria isn’t over yet…

… however, I hope you were not stupid enough to follow the advice of this site which suggests you to download some random file over the ’net and execute it with superuser permissions, unchecked. (I think the Ruby people were the first to spread this extremely insecure, stupid and reprehensible technique.)

Thanks to ↳ tarent for letting me do this work during $dayjob time!
