Hi all,

for all those who haven't been on saag WG at IETF 88...

Amir Herzbert and Haya Shulman has presented a quite interesting attack on UDP fragmentation that allows Kaminsky-style attacks to be real again.

The saag presentation is here: http://www.ietf.org/proceedings/87/slides/slides-87-saag-3.pdf

The paper describing the attack is here:
http://arxiv.org/pdf/1205.4011v1.pdf

More Haya Shulman's publications can be found here:

And some papers are also available from Google Scholar:
http://scholar.google.com/scholar?hl=en&q=Amir+Herzberg%2C+Haya+Shulman+++dnssec&btnG=&as_sdt=1%2C5&as_sdtp=

We gave it some thoughts here at CZ.NIC Labs and we think that the threat is real and we are now trying to write a PoC code to prove the theoretical concept.

So what are the views of other people on this list?
