Ubuntu 22.04 & RHEL 9 are the major distros impacted. Docker images built on ubuntu:latest will also be impacted. The latest releases of Alpine/Debian/AL2 are all not impacted, they use 1.1.x lineage.
That was, as it turns out, the only OpenSSL 3 host I'm presently dealing with.
>If you’re using version 1.1.1, this vulnerability doesn’t affect you, but there is a 1.1.1 update coming on Tuesday as well, version 1.1.1s, which you’re still going to need to update to anyway so you might as well schedule some time on Tuesday, too.
