Use AF_UNSPEC as the default family in IO::Socket::INET

Now that IO::Socket::INET actually sets the family of a socket given the one passed to .new, the default needs to be changed to AF_UNSPEC rather than AF_INET to maintain compatibility with older code.		 21:47

kiwi_50 hi all, I have what I believe to be a significant DoS attack on Rakudo. I would like to report it in an appropriate private manner. Is there a documented process I can follow? 22:04
22:06 pamplemousse left
timotimo we don't have that kind of thing set up yet, this might be the first security-relevant problem we've had reported 22:06
kiwi_50 That's what I thought. The question is, now what?
timotimo i'm trustworthy! but just telling me what it's all about is not really a "process" at all 22:07
the problem-solving repo we just recently opened would be a good place to have a "how will security issues be handled" ticket with discussions
[Coke] There is a mailing list, IIRC, but we never finalized the documentation. 22:08
Please open the meta-ticket to drive the process?
timotimo oh, can i get on that? :)
lucasb is curious to know whats the problem 22:09
timotimo the most difficult part is, you must keep quiet about the actual problem until a security patch and related mitigation info is available for the public 22:10
[Coke] ah. the list was hosted as part of RT, I think.
So I would totally get whatever the new hotness is setup.
timotimo welp, that's gone now
[Coke] we got it setup near the original xmas release, and it got a test email, and that was it, unfortunately. 22:11
MasterDuke maybe a one-time-use-only workaround would be to cross-reference the CREDITS file with some of the top contributors and send them an email directly? 22:13
timotimo the problem-solving repo's readme has the "labels and responsible devs" section 22:14
rakudo and moarvm both have jnthn listed there
i'll open that ticket in problem-solving 22:15
github.com/perl6/problem-solving/issues/92 22:22
kiwi_50 Someone else that's P6 friendly posted about the problem. They've since removed their post. I will link to a gist that reveals what I think it's safe to reveal showing how the discussion and actions have unfolded so far. 22:23
timotimo sounds good at first glance 22:24

Geth ¦ problem-solving: AlexDaniel self-assigned there is no security process for receiving security critical bug reports github.com/perl6/problem-solving/issues/92
timotimo is it fine to put their email address up publicly like that? 22:29
oh, raiph, is that you? kiwi_50 22:30
kiwi_50 gist deleted
jnthn kiwi_50: In the meantime, you can contact me with the private details (I see Cro is mentioned, and I'm also a lead developer there)
kiwi_50: [email@hidden.address]
AlexDaniel jnthn: do you have a gpg key and can you read encrypted mails? 22:31
jnthn And yes, we should document better what to do, as well as do something that allows for more than one person to be contacted.
AlexDaniel: No; if you can and that is important to the submitter, then it's better that it goes to you.
Oh, and: if gmail does encrypted mail out of the box then I can without knowing it :)
I've just no awareness it does. 22:32
timotimo you'd really want end-to-end encryption without a web interface doing it for you :)
AlexDaniel no it doesn't
that's right
kiwi_50 Fresh gist w/ email redacted. I didn't think it was a problem, but I don't need to rely on what I think. :)
gist.github.com/raiph/7a1e1f81ce2c...d4ae8d3f64
Note that I'm not applying NSA levels of care here and it's too late to do that anyway. 22:34
The original post was online for up to an hour. Someone even posted a comment analyzing. Quite plausibly a hundred folk have read it. 22:35
And we're talking P6 here. I love P6 but it's not especially widely deployed yet. :) 22:36
jnthn Better for us to go through the CVE dance while we're not, so we learn how to handle it. 22:37
kiwi_50 My preference is that we are suitably formal about how we develop this but I also would like to share the bug with jnthn asap.
Right.
AlexDaniel jnthn: like this? github.com/perl6/problem-solving/i...-522780268
timotimo you can also show it to me! :3
jnthn AlexDaniel: That's fine for now. Though really we'll want to set up a way for a few people to be notified, to increase the chance of a fast response 22:39
AlexDaniel what about using hackerone.com/ or something like that? 22:41
I don't know how well it can work for perl6, but that's the thing that github is using (like if you find a security issue on github itself, you submit it there)
I don't know if bounties are required but surely we can throw at least some amount of money into that, no? 22:42
kiwi_50 timotimo: The irony is I was in the middle of typing a comment saying I wanted to share the bug with you first, but then you mentioned the email, and then jnthn turned up. :)
and yes, i'm raiph
timotimo hah 22:43
i should probably get a new pgp key 22:44
i was once dilligent at visiting key signing parties
22:45 BeastieBot left, BeastieBot joined
timotimo anyway, the mail you'll reach me at would be [email@hidden.address] 22:46
kiwi_50 jnthn: I'm of the opinion that any attack, no matter how bad, at this early stage in P6's life isn't something NSA crack worthy. That is, I feel I can just send you a private IRC message or just a plain text email and, even say so in this publicly logged IRC message and it'll be fine. Am I nuts? Would you prefer I'm more cautious about it? The bug 22:47
is dramatic but I'm mostly doing this so we can take the *process* seriously.
leont has not-so-good experiences with hackerone and perl5, TBH 22:48
AlexDaniel leont: more info? 22:49
leont A lot of people don't even read the page well enough to realize it covers the language and not any of the perl.org websites.
jnthn kiwi_50: I'd prefer to get it by email then privmsg, but anything is better than a bug I don't have any information about, so can't fix. :) 22:50
That said, it's about bedtime for me, so maybe including timo or AlexDaniel would get things moving faster. 22:51
leont People who actually do come with issues often want to call every bug a vulnerability.
An overflow in the parser is a bug, but not really a vulnerability because if an attacker can add arbitrary input to that he doesn't need the overflow.
Not saying it's all bad, but it does bring a lot of noise 22:52
AlexDaniel that doesn't sound too bad to me 22:54
better than having no proper place to submit security reports
bug reports* :)
jnthn How easy is it for anobody to submit there? 22:55
AlexDaniel you have to register… :) 22:57
but otherwise it is convenient, I liked the process
jnthn OK, sounds promising 22:58
Though with the caveats leont++ mentions, but I guess if it's a well-known directory for finding how to disclose, it's perhaps better to be there on balance. 22:59
