which implement IKEv1 are flawed, since they follow this protocol

Many protocols could be described as "flawed." The IKEv1 protocol amplification concern does not make it flawed in a 
way that would lead to a per-protocol
CVE ID assignment. We are maintaining the CVE-2016-5361 ID assignment for the upstream announcement of "libreswan 
3.16 vulnerable to DDOS attack. Please
upgrade to 3.17" and accompanying upstream patch, as described in the 
http://www.openwall.com/lists/oss-security/2016/06/10/4 post.

<with upstream libreswan hat on>

If you want us to keep honestly reporting security issues, I recommend you
not single out single implementations over RFC compliant protocol flaws.

I'm fine if you list the CVE with the 6 vulnerable implementations, then say
libreswan has fixed it.

I'm not okay with libreswan being listed as vulnerable and the other 5 vulnerable
implementations not being listed.

If you keep the CVE as-is, we will document it at libreswan.org/security/ as a
mis-issued CVE entry.

Related, I would _REALLY_ appreciate it if MITR talks to us before issuing CVE's
for our software. We've been at this long before MITR, we respond within days, we
are known to have coordinated CVE issues for IKE implementation issues across
various implementations. You can contact us at security () libreswan org, PGP key
available at the usual places.
