Why not? History shows that this assumption will almost always be
correct for WebKit.

Besides, this doesn't seem to be what's
happening in practice. For example, WSA-2021-0006 was released on
October 26, 2021 with vulnerabilities addressed in 2.34.0, released on
September 22, but RedHat's bugs for it were only opened in the days
after the *security advisory's* release, not the software release. It
doesn't help that most most distribution security tooling seems to be
oriented around CVEs, which aren't released for WebKit until after the
associated advisory.

I'm sure that Red Hat's package maintainers know what a WebKit update
means. Presumably they are busy and their KPIs prioritize fixing CVEs,
so they don't act as proactively as one might prefer.

In general, it seems that WebKit is handling these issues like Linux.
Observers know that important bugs are fixed constantly in software of
this size and complexity. Relying only on CVEs is too reactive and
limited in scope to provide a meaningful security stance, increasingly
so since the CVE assignment system stopped working in the last few
years.

This isn't an argument against WebKit Doing The Right Thing (TM).

There's no need for us to rehash the standard arguments for/against
bothering with CVEs at all.

The point is that CVE notifications are useful for some of us and
it _seems_ (obviously I can't know) that they're intentionally not
published at the same time as release notes, often a week or more later.

I, and John, are just saying that if possible, it'd be a big help for
them to do so.

Best,
sam
