As we know, CAcert Inc. is incorporated in NSW, Australia under the Association Incorporation Act 1984. That Act has now been updated to the Association Incorporation Act 2009, which is expected to come into effect during late 2009. Once in effect, the new Act will apply automatically, which means that any changes required will have to be aligned with our rules.

For CAcert Inc. the most significant change, among other changes is, that three (3) committee members (CAcert Board) will have to reside in Australia. Other relevant changes will come into effect as well. This gives us tasks: to evaluate consequences for CAcert Inc. and for members, and propose any changes required at a General Meeting.

There is much news lately about the Null-Stuffing attack to SSL presented at BlackHat by Dan Kaminsky, Len Sassaman and Moxie Marlinspike. Quick answer: Our current assessment is that we were “probably not” vulnerable to this particular attack.

Bug: there is a theoretical possibility to create a certificate for example:

myspace.comNULLmy.cheapdomain.com

A CA might check the domain, and end up accepting a POSITIVE on the second part only. Meanwhile, a browser might show the first part, because it is written to stop processing when it sees the NULL . This is because NULLs are special characters that might be interpreted as the end of string, or might not be, and a browser might mistake it one way while a CA another way.

Analysis: At one level this is “just” input validation, and both browsers and CAs should reject immediately. At another level, the code that manages this input is very complicated, because of the way certificates are built. Too many standards, layouts, encodings. Hence the comments by many that this bug is actually indicative of systemic weaknesses in SSL. Technically, implementing SSL properly means this isn’t possible, but the system is so complex that it isn’t easy to rule out these sorts of issues. But, we don’t win anything if we pass the blame onto someone else, because we’ve still got the bug. Basic technical conclusion is that we need to check our inputs carefully, and hope that others do the same.

CAcert. So where are we at? Is CAcert vulnerable? This boils down to whether CAcert can issue a certificate with a NULL stuffed into a domain name. Which is in two parts: adding a domain name to your account, and sending in a request for a certificate (CSR). Investigations are on-going, but here is a status update:

• Adding domain names is now covered with a quick fix that was patched in Friday.
• CSRs were already being filtered on NULLs, so someone was alert back in the earlier years!

What is outstanding is checking that the database copy of the domain name is used instead of the CSR, and scanning the database for any NULLs. It’s still not entirely clear if there was a way to sneak a NULL through before that patch in, but it’s covered now. This work is ongoing, and updates will be reported here.

The CAcert Email System went down Friday fornoon 31th of July 2009. This problem caused that no emails could be transferred. The systems team works on it to solve the problem.

update:
After a reboot of the server, the Email system is working again. Multiple non-critical services were affected to a more or less extent. The cause was a problem with NFS.

CAcert Inc, the association within the Community, held an SGM or special general meeting on Saturday 21:00 UTC. Which makes it evening in Europe, afternoon in the Americas, and tomorrow morning in Australia.

Between 38 and 42 members were present. 4 business items were duly filed (21 days in advance) and were dealt with in the meeting.

#1, that pending applications for joining the association be accepted was passed with no vote, because all applications had already been dealt with.

#2 is a comprehensive rule change that (among other things) asked to do this:

• made the status of Assurer the only requirement for membership of the Association,
• increased the size of the board to 10,
• rewrote and fixed up lots of other bugs in the rules.

It was voted and achieved 24 AYES against 14 Nayes. As this is a rule change, it required 75% and therefore failed. But, a good showing.

Item #3 was the controversial one. The first resolution said we association members were “disenheartened at the breakdown of working relationship.” It passed with 35 AYES to 5 Nayes. The second resolution said “the committee no longer enjoys the confidence, of the members, and [they] are removed.” It was duly voted and passed with 20 AYEs to 16 Nayes. With that resolution the board was relieved and opened for the next item.

The final business of the day was to elect a new board of 7 seats for an interim period of 4 months, until the next AGM. This was conducted on a person-by-person basis, and the 7 top-voted candidates were chosen:

Name	Position
Nick Bebout	President
Mark Lipscombe	Vice-President
Ernestine Schwob	Secretary
Philipp Dunkel	Treasurer
Guillaume Romagny	Ordinary Member
Andreas Buerki	Ordinary Member
Ian Grigg	Ordinary Member

This is the new committee of the association, or board. Please note:

• the committee will adjust the positions somewhat, and
• this committee is interim only, in place for 4 months. At the AGM, traditionally in November, they will stand down and face re-election.

Postscript: By means of m20090728.1 the committee agreed that Ernestine Schwob is now Treasurer and that Philipp Dunkel is now Secretary. No other changes are envisaged.
