This exploit was in the linux code for a long time and was never discovered.  It was revealed only by the developer himself, and only because he was retiring.  Point is: Code is often complex, especially that written in C (or C++ and others), so much so that an exploit can be written into it and not discovered for a long time, or ever. This is yet another argument against systemd: it would be much easier to hide an exploit in it than in a handful of bash scripts.

When you say “one of the linux developers”, you mean Ken Thompson?

This story predates Linux, and describes a problem with any potential software.  

You realize ‘bash’ could be just as malicious as systemd in this scenario?  Are you meticulously going through *it’s* source code in your version of the world?  Note:  bash is not written in bash.
