Hi,

Thanks for posting this, Marc.

Just to clarify: this "half a year" delay occurred before Marc notified
the distros list, which he did on September 20.  (I was not aware of
Marc's work on this before that date either.)  Thus, as far as the
distros list is concerned, the issues were reported to distro vendors and
embargoed for 20 days, which is a slight violation of the list's policy
(14 to 19 days max, depending on day of week).  I apologize for this.
I did not insist on Marc disclosing the issues publicly sooner than he
wanted to for reasons similar to what we had with hashDoS last year
(just a DoS, which the researchers wanted to disclose at a certain con),
although I did remind him and recommend posting to oss-security sooner,
so that I wouldn't have to apologize. ;-)

It appears that vendors did not care to patch mere IPv6 DoSes promptly
enough anyway, so the embargo did not help.

Notifying the distros list closer to the intended public disclosure date
would be more appropriate - it would reduce the window of partial
exposure.  Not providing any advance notification would be even better
in this specific case (since apparently no action was taken anyway), but
this was impossible to know reliably in advance.

Thanks again,

Alexander
