Hello,

My apologies if this is not the right place to discus this.

I would like to ensure that I stay informed of any potential future security issues in python (specifically at least the cpython runtime and standard library, although select very-popular 3rd party libraries wouldn't hurt). I cannot find a single place where such announcements are guaranteed to land.

Good examples of the type of thing I am looking for are the openssl-announce list [1][2] and the golang-announce list [3], where the projects pre-announce "Hey, we're going to have a release on <date> which addresses a <rough severity> security issue in <vague area of impact>." and then announces again when patches are available such that responsible maintainers (such as I am trying to be) can ensure that updates are available to our users ASAP.

The python-announce-list [4] does not serve this purpose because it has lots of noise from initial release announcements about random 3rd party stuff, and the "security news" page [5] is really just a "how to disclose vulns" page.

Note that I'm *not* advocating for the creation of a pre-disclosure list! Python is such a ubiquitous piece of software that I don't think it's reasonable to expect that such a list could contain all affected parties without also leaking details to those who would cause harm. I'm only asking for something public that I can subscribe to in order to be sure I'll have a heads up of when patching is imminently required.

Regards,
Jean-Philippe

There is Security SIG mailing list, please check it out:

Ah, I now see there actually *is* a security-announce list [1]!

Unless one happens to already know that Python has two concurrent mailman instances hosting different lists [2][3], it's easy to miss.

Thanks, and sorry for the noise!
