Nginx Security Advisory (mailman.nginx.org)

Interesting, this is just an hour before the core dev quit because of disagreements on how security is managed at F5.

And to be clear, the disagreement appears to be that he did not want the CVE to be assigned.
This has been an issue in the past, where NGINX disagreed with a CVE being assigned, but a CVE is the easiest way to get a vulnerability fixed across the ecosystem and in the distributions that distribute NGINX.

Each time something is silently fixed it takes much longer and is much harder to actually get the fix approved/backported/whatever is necessary to get it fixed.

Except that no one is shipping with QUIC enabled. It's marked as experimental, so if you are deploying on prod you are asking for it.
Asking for what?
source?

MegaZone is part of the F5 Security Incident Response Team.

And just so that he doesn't have to explain it: yes, it's his legal name, and yes, it's a mononym.

Source: we were coworkers before F5.

How does filling in the last name (or first) on forms work when mononyms are involved?
Ah, thank you
Thanks. Guess we are in some interesting times, again.
This seems like mostly a non-issue, since this module isn't compiled by default. I guess it's good to fix it regardless, but it seems unnecessary to issue a security advisory/CVE for this. HTTP/3 is an experimental feature in nginx that isn't built by default and isn't included in most distribution builds.
Still being investigated apparently. From what's known, they haven't been labeled as RCE's at least.
It is not still being investigated. The issues are understood. Patched versions are released.
I'm a novice at nginx and using modules. how do I figure out if the nginx docker images that I use are effected by this? it looks like the default image uses `debian:bookworm-slim`. is it safe to assume that the compiled version in that upstream image isn't using any additional modules?

> The issues affect nginx compiled with the ngx_http_v3_module (not compiled by default) if the "quic" option of the "listen" directive is used in a configuration file.

Hi!

The official nginx docker images ship with HTTP3 module enabled - and we have released the updated ones earlier today - so please update to stay secure.

You can also launch something like: $ docker run -ti --rm nginx:latest nginx -V

to check which modules are compiled in to the binary you're running.

Thanks!

Why are they enabled by default while this page says otherwise?: https://my.f5.com/manage/s/article/K000138444

  Note: The HTTP/3 QUIC module is not enabled by default and is considered experimental.
Because they are not so "official" maybe?
Will this affect http/2 as well?
This is limited to just HTTP/3.
To just the experimental QUIC element of HTTP/3.
