So on that note I'll be more direct. Has anyone actually preemptively

know, attempted to understand the vulnerability in detail instead of
relying on these intentionally vague advisories (dan)?

my money is currently on ICMP port unreachable combined with the
predictable ports to trick vulnerable resolvers into thinking the
configured nameservers are offline:


you could fix this via the method described, and not imply that the
ICMP was part of the vector.
