      HackersNews (note the plural) has *always* been shoddily researched clickbait

      Sure, it may not be factually wrong, but the title is very misleading. And nowhere in the article do you explain how small the actual security implications really are.

      The article is *more* confusing than the original vuln report, which clearly stated the vulnerable config. By dressing it up in all that superfluous info, you dilute the message of the limited impact. More info is appreciated *only* when you take care to keep the message clear.

      It only affects configurations that restrict access as root *but allow access as -1*, i.e. use ALL. The way you phrase it it sounds like it affects any config that allows access as a user or group that isn't root.

      Replying to @marcan42 @unix_root and

      You also mention "arbitrary commands" while any config that allows "arbitrary commands" as ALL, !root is already almost certainly vulnerable per se and a terrible idea and nobody should be doing that.

      If nobody should be doing that then hopefully nobody is doing that, which makes the impact minimal, which means it's your job to minimize confused panic from those who might misunderstand otherwise.

          I had at least 5 people link me the sudo bug, some directly via your article, because they though it was some huge security hole affecting many Linux systems.
