"moderate" makes sense here; those are issues that needed fixing, but they wouldn't give someone privileged access they shouldn't have, and they occur in non-default configurations.

I stand corrected, you're right. I misread the description of the vulnerability.

I'm surprised how little attention this is getting on HN.

Not sure what's news-worthy here? Safe Rust eliminates certain classes of bugs, not all bugs. The editorializing of the title seems like strawmanning.

A bug in Ubuntu's standard sudo executable is newsworthy.
Updates are probably required for a large number of servers.

This never affected any servers, because non-LTS ubuntu versions are never used in productions. They are essentially treated as betas.

There were two very serious issues in original sudo this year. I can't find much info about them on HN.

The drive to rewrite existing, tried and tested code in the new trendy language is crazy. Hopefully problems like this will be a bit of a reality check for those cheerleading it.

What kind of reality check would it be when the original sudo got two even more serious security issues this year, even though it's "tried and tested"?

It does, quotes from https://github.com/trifectatechfoundation/sudo-rs/security/a... below:
