      Can we please stop talking about that sudo bug? It only affects systems using an insane configuration (allow $command as anyone *but* root). I can't come up with any situation where that configuration makes any sense (vs e.g. "allow $command as any member of a given group).

      "allow $command as any member of a given group" http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-14287 … i said "given group", not "root group"

      If root is in the given group and you allow sudo to that group then you allow sudo to root, obviously. Not sure what you're trying to get at?

      because the *exclusion* of root user breaks in this case when it oughtn't. i'm saying in the example you provided, if root user is in the group but you explicitly exclude root as a user (!root), it's still able to be switched to.

      No, it won't, because '-1' is not in the group.
