It merely says:

	All instances across the Amazon EC2 fleet are protected from
	all known threat vectors from the CVEs previously listed.

not spectre in general.

But, as mentioned in:

	https://access.redhat.com/security/cve/cve-2017-5715
	It relies on the presence of a precisely-defined instruction
	sequence in the privileged code

and

	https://access.redhat.com/security/cve/cve-2017-5753
	It relies on the presence of a precisely-defined instruction
	sequence in the privileged code

CVEs previously listed are spectre attacks between privileged and
unprivileged codes, which means spectre attack between
unprivileged codes is still possible with AWS, which is why
we should avoid cloud servers, until CPU hardware is fixed.
