Okay, so how would they do that?  I understand how that would happen if
it was an external extension, but how if it is under /src or /contrib.

FYI, I see a good number of curl CVEs:

	https://curl.se/docs/security.html

Would we have to put out minor releases for curl CVEs?  I don't think we
have to for OpenSSL so would curl be the same?

I am asking these questions now so we can save time in getting this
closed.
