 Ehem, is it your idea of security to make it secret (like Microsoft do
 often)?

Well done; a straw man combined with an implication of an ad hominem.
That always really impresses me.

 It is never ever a good idea to make security issues secret or
 protracting it.
 
 And in this special case it was easy to fix the problem very fast when
 the advisory cames out.

Let's say you'd been asleep at the time, and the advisory had laid out
everything necessary to make it trivial to produce an exploit (it could
easily have been much more explicit than it was, and even with limited
information it only took a day and a half to produce an exploit; a
couple of hours would not at all have been out of the question). Would
you still feel the same way if your accounts had been compromised?

If we had released any sooner, the OpenSSH blacklisting support would
not have been available, and every system administrator would have had
to figure out what was going on by hand rather than have the upgrade
automatically deny attempts to exploit this vulnerability. If we had
released later, a number of flaws in the blacklisting support could have
been fixed, alleviating a great deal of confusion among system
administrators (I spent considerable time that week supporting people
confused by the new tools), and I doubt it would have made much if any
difference to exploit production.

  but I think an extra day or two on the embargo period would very
  likely have produced a better result.
 
 It is never a good idea to set a embargo period for a security issue.
 This is more valid for the scope of this big security problem!

If it had been released without an embargo, many more systems would have
been compromised, and (given the severity) it's entirely possible that
somebody would have managed to write a worm that took advantage of this
to seriously damage Internet infrastructure. It's as simple as that. We
used the embargo period to develop tools to help system administrators
defend themselves, not to sit in a smoke-filled room gloating that we
knew a secret and you didn't.

I believe wholeheartedly in full disclosure of all security problems.
Nothing else ultimately makes sense, particularly in the free software
world. That doesn't mean I think we have to actively help the black
hats; a few days of advance notice is just about all the advantage we
have, and we desperately need to make good use of it.

 All together I must say it was very professional and fast how the debian
 security team and other had done the treatment of the problem. Don't
 lower them by arguing with snakeoil about that the reaction was to fast!
 It can never be fast enough.

Note that I was myself heavily involved in producing some of the fixes
that went out in Debian security advisories. If the people directly
involved are not entitled to make comments on the process, who exactly
do you think is?

I think everyone involved did a wonderful job, especially given the
appalling constraints they were under. There is a difference, though,
between acknowledging the excellent work that was done and burying one's
head in the sand claiming that nothing could possibly have been
improved.

A wonderful job indeed. *Thanks* from this corner of the world to the
Debian + Ubuntu team involved. The efforts in getting it all done
while balancing the maturity of the SSH blacklist patches  scripts vs
risk have been excellent.

It was a hard day for everyone else too, but it is clear that it would
have been much worse without such careful handling of the situation.

Open source development does work well only if splitting up the
development in different branches or even forks is strongly
avoided and done only if it is strictly necessary. IMHO the
Debian way of doing things makes it far too easy for package
maintainers to diverge from the upstream source. I can't really
comment on the examples you have provided, but in general, I feel
that Debian has not found the right balance here.

I personally often discuss the patches with my upstream (but then,  
they're really responsive). Most of the time they apply it to their  
CVS, and I backport their patch (generally improved over my  
approach). If a patch fixes a real bug and looks simple enough that's  
its unlikely to break anything, I think it's useful. Other patches  
are not supposed to go to upstream, because they are just meant to  
implement the Debian policy (also I generally tell upstream anyway,  
to have their opinion).


Of course you need to define simple enough, and unlikely (for  
openssl, you want it to be _very_ unlikely). I agree with you that  
patching should be kept to a minimum : back-porting bug fixes and  
implementing Debian policy (even there, I would try to not overdo it,  
but a must in policy is a must).


By the way, Debian policy is not completely silly, so even those  
patches can often go to upstream and be shared with the other  
distributions, of be configurable at build time. For instance, my  
main package, yorick, traditionally expects user files to be in ~/ 
Yorick/. Those files can be considered configuration or data, that  
really depends on the user. I've triggered a discussion on the matter  
that configuration files in a user's home directory should be stored  
in hidden files or directories (that's from the FHS). Yorick now  
looks at both ~/.yorick/ and ~/Yorick/, so the user can choose. I was  
motivated by abiding by Debian policy, but the change was made  
upstream, to avoid a fork. If upstream had rejected the idea, I'm not  
sure what I would have chosen. I tend to believe the right thing to  
do here was to avoid a fork at all cost, but others may disagree.


Let's hope this discussion will, in the end, bring good ideas and  
trigger actual work to improve Debian, and perhaps the free software  
community at large.


Best regards, Thibaut.

2008-05-16 Thread Miriam Ruiz
2008/5/16 Thibaut Paumard [EMAIL PROTECTED]:

 the topic has already been changed to ssl security desaster, and in my
 opinion this is precisely what my post is about: what can we learn from this
 disaster. (More precisely, I'm giving my 2c on what level of patching is
 acceptable in a Debian package. Since the disaster allegedly originates in
 abusive patching, this is relevant).

I disagree. The cause of the disaster was not that Debian does its own
patching, but the fact that that patch was buggy. On the whole I think
that Debian benefits a lot from custom patches, and in fact many
packages would be severely buggy and/or wouldn't integrate properly
with the rest of the system without them. It's not a secret that many
projects benefit from Debian patches, so there might be something good
with them. Also, I don't think we should always wait for upstream's
new releases for adding them if we have them available. It might
depend on every case.

Maybe there's a problem with the fact that some of those patches are
just reviewed by just one person, but then again, I seriously think
that it would have been quite difficult to discover that there was a
problem with this one. The proof that it wasn't evident is not only
that upstream didn't see the problem either, nor any other developer
or derivative distribution or independent reviewers in 2 years.

I think that defending the position of using pristine upstream source
code are just a conservative position to guarantee that we can blame
upstream or someone else if something like this happens again, not
that bugs won't happen. Only those who don't do anything don't make
mistakes. The point is to try to avoid mistakes, not to be able to
blame upstream. Of course, the development and checking of the patches
should be done as cooperatively with upstream as possible, as upstream
might see something we're not seeing, but the way to the solution, in
my opinion, is not to avoid patching but to develop a way to check
them as extensively as possible. Maybe there should also be a
clasification of packages according to how bad would a bug be in them
for the whole system, so that patches in those could be more carefully
reviewed.

Greetings,
Miry

If I understand this correctly, this means that not only should keys

keys which were potentially used to create DSA signatures by those
broken libs.

In this case, the security advisory should clearly be updated. And
all advise about searching for weak keys should be removed as well,
because it leads to false sense of security. In fact, *all* keys used

I also wonder, what will the Debian community change in their

Something as bad as this might be rare, still, if something can be
improved, it should.

Upstream complained about the extensive Debian patching. I think this
is a valid criticism.

For security sensitive packages, requiring changes to be signed-off
by a second person might be a good idea too.

Another problem I have argued about before, not directly related to this
incident, but IMHO another desaster waiting to happen: There is no
way to independetly validate that a debian binary package was
created from the corresponding source.

What bothers me too is the fact that the installer scripts of 
all packages have root permissions during installation. While
this might be hard to do, in principle I see no good reason
why installer scripts could not be limited to certain tasks.

Leaving millions of systems open to crackers for 2 years out of 15
is not a joke.  I don't blame the DD - we have all made mistakes
and most of us are lucky they weren't this serious - but we should
blame the process.  And fix it.

The notification process, with the fix in the archive long before
users were notified, failed to live up to Debian's usually high
standards.  The delay in getting some of the fixes into Testing
may also be an issue.

The rollout of information and updates was appalling - even adding in
the material from Ubuntu the information was piecemeal and inadequate
to properly secure systems within the limited time before crackers
might be expected to have exploits.

The vulnerability scanner didn't handle keys in many forms (e.g.
Apache keys) and gave false negatives because it doesn't use
~/.ssh/config to check the correct port in the common case where
ssh is running on a port other than 22.  In the wonderful light
of hindsight, it would probably have been better to devote less
effort to the scanner and more effort to documenting all the
kinds of key replacements that are needed, and to simply assume
that all keys are potentially compromised.

Serious efforts are needed on two fronts.  Second, we must ensure
that nothing like this ever happens again.  This calls for a thorough 
investigation and carefully updated policies and procedures.  It will
take a while to do properly.  It must be apparent to both the Debian
community and the world that the effort is authoritative, sincere,
and open.

But first we must carefully avoid any communication, however intended,
which might be construed as a flippant attitude to this disaster.

It only takes one incident as bad as this to compromise millions of
systems and to seriously harm Debian's reputation.  You can't average
out over all packages and say Debian is 99% secure.

99% secure is 100% insecure.

This incident needs to be reviewed carefully but the time is not yet.  
Information is not as accessible to Debian users as it should be and
some packages don't seem to have reached Testing.  Focus at this time
must still be on disaster response and recovery.

Next come the most important phases - learning from this disaster,
ensuring that a repetition is impossible (or several orders of magnitude
less likely), and preparing Debian's response for the next disaster.

Why not? A plane crash is a very rare incident. Still every single

Maybe that wasn't clear from my first mail, but I don't think that nothing can

that the conclusion that Debian patches too much is at all justified when 
looking solely at this bug.

I can understand that this doesn't seem necessary from the outside. However, 
I've been working on Debian for a few years now, and I've come to see that 
large numbers of patches are very justified. For example, because upstream 
isn't quite as cooperative, or even responds at all. Or because upstream is 
not interested in problems that affect Debian users specifically. There are 
many more examples, and probably also quite some counterexamples. There's a 
net win there, however.

Let me state it again, surely things can be learned from this incident, but 
the general conclusion that Debian patches too much is in my opinion far from 
justified. And I think it would be a good idea to get more overview of the 
reasons that these patches are applied before drawing the conclusion that 
it's a bad idea.

If you see packages for which a Debian-specific patch seems unnecessary,
please by all means file a bug (severity wishlist) requesting that the
patch be either reverted or submitted upstream.  The worst that can
happen is that the bug will be ignored or closed with no reason given by
the maintainer.  More likely (at least I hope so), you'll either get an
explanation of why the patch is needed, or have your request to remove
the patch actually implemented.

even before they gave up the ghost, they were very conservative,

The Debian-specific patches (which have also been incorporated into
Fedora's packages) incorporate things that upstream was unwilling to
include, such as:

- building shared libraries instead of only static ones
- support for architectures other than x86 and powerpc on Linux
- minimal 64-bit support
- support for newer compilers (gfortran instead of g77)
- fixes for bugs when programs were built against lesstif instead of
  the non-free OpenMotif (upstream did not see any reason to support
  lesstif)
- removal of non-free code, and fixing the build system to work
  around this removal

Believe me, there are lots of upstreams for which extensive patching
really is necessary.  (I have no idea whether OpenSSL is one of those,
as I have no familiarity with its code nor the Debian packaging of it.)

best regards,

 but we should blame the process.  And fix it.

 it would probably have been better to devote less effort to the
 scanner and more effort to documenting all the kinds of key
 replacements

 Serious efforts are needed

 Second, we must ensure

 This calls for a thorough investigation

 we must carefully avoid

Who is this we?  Whose serious efforts?  Who is investigating?  Most
importantly, should we assume that, as in the past, you, Mike Bird,
intend to do nothing but talk?

Debian is still one of the world's best distros and I hope it
continues as such.  I use Debian on more systems than any other
distro.

Yet Debian makes it hard for people to help.  Like most software
engineers I simply don't have the time to waste on Debian's NM
process.  Debian's processes are indisputably Debian's decision
alone, but Debian has to live with the consequences ... falling
mindshare, orphaned packages, and slow releases.

Nevertheless, non-DD's can and do help by filing bug reports and
patches (upstream is best), helping people on d-u, and offering
constructive advice to DDs.  And one should not forget that most
of the software in Debian is developed and maintained by non-DD's.

Very well.  I propose that anyone who wishes to give constructive
advice to developers, but who doesn't actually do any of our
development work, should use the pronoun you rather than we.

This might make your posts sound like you're trying to boss us around
... but that's exactly what you're doing, so it's basically more
honest.  I prefer honest bossiness to implicit bossiness.

Hi,

And maintaining packages! It can be long to find a sponsor for your  
first package (especially if it's a very specialized software no DD  
uses), but you don't need to go through NM to become a (co-) 
maintainer. If you feel the itch, please step forward of adopt an  
orphaned package, as you noted there's a large pool to choose from.  
If you look a package with a request for help, you're sponsor is  
found already: your prospective comaintainer.


Besides, many packages are orphaned because they are obsolete. If  
nobody adopts them and they get too buggy, they'll be terminated  
eventually. The only alternative would be to remove them right away  
when the maintainer feels he doesn't care anymore, but this would be  
worse (unless the package was so obsolete that only the maintainer  
still used it).


Cheers, Thibaut (DM, not DD).

While we all thank you for the great amount of work you put into Debian
[1] [2], I personally prefer to be told what to do and think in a slightly
less agressive tone, and by someone who knows slightly more about the
subject at hand.  I understand that those 6 bug reports probably took
quite a lot of your valuable time, and I don't mean to denigrate that.

If you feel that the NM process may be too rigorous for you, there are
plenty of other ways to contribute to Debian.  Perhaps you could tell
us what obstacles we have put in your way (I'm assuming that all these
efforts like DM, alioth packaging teams, QA efforts and so on don't
present a low enough barrier to entry for you, so we won't sully this
conversation by mentioning them).

Again, really, thank you.

I think this is a common stylistic choice.  I consider myself part of
the Debian community, though I don't contribute very much directly.
When I post to Debian lists, I frequently use we as both a means of
building on an existing community feeling and occasionally to soften
criticism.  I don't use it to claim credit.  I assume Mike uses it the
same way.  In the future, I'll keep in mind not to lump myself with
Debian developers, to avoid this sort of misunderstanding.

In that spirit, maybe YOU should all be more careful about YOUR
pronouns, too.  After all, one of YOU, namely Thijs Kinkhorst,
followed up to Martin Uecker (one of US) with:

 You mean less likely than once in 15 years? We're open to your
 suggestions.

Some of US (not YOU, just US) may have interpreted this not as
pointless sarcasm but as a genuine call for constructive criticism
from US.  If YOU had meant to solicit just Martin's suggestions and
not to hear any suggestions from any of the rest of US, then YOU could
have been more clear in YOUR wording.

Thank YOU for YOUR continued work on Debian.  Despite the occasional
misstep, WE appreciate YOUR efforts.  If YOU ever *do* want to hear
any of OUR suggestions, WE'd be happy to share them, but please be
explicit when YOU ask, so WE don't embarrass OURselves again.
