Matt-

The outside XML can be tampered with since there's no ability to = verify
it's integrity (HMAC's obviously difficult to apply to the work on = the
container stanza). Putting the version in the encrypted payload = gives
you an extra level of security to validate that what's on the = container
matches what's in the payload. Further, if you have some known = "phrase"
that the encrypted payload always begins with, you have a quick way = to
check and ensure that your decryption was successful before spinning = up
your XML parser.

You could always just put a plain text version of the namespace as = the
first N characters of the encrypted payload, but I think something
that's more deterministic (a known length) would be desirable.

Ben

Internet-Drafts directories. This draft is a work item of the Extensible Messaging and Presence Protocol Working Group of the IETF. Title : Extensible Messaging and Presence Protocol (XMPP): Core Author(s) : P. Saint-Andre Filename : draft-ietf-xmpp-3920bis-07.txt Pages : 169 Date : 2010-04-07 This document defines the core features of the Extensible Messaging and Presence Protocol (XMPP), a technology for streaming Extensible Markup Language (XML) elements for the purpose of exchanging structured information in close to real time between any two or more network-aware entities. XMPP provides a generalized, extensible framework for incrementally exchanging XML data, upon which a variety of applications can be built. The framework includes methods for stream setup and teardown, channel encryption, authentication of a client to a server and of one server to another server, and primitives for push-style messages, publication of network availability information ("presence"), and request-response interactions. This document obsoletes RFC 3920.

That's a matter for discussion. The security folks I've talked with suggest that it's easier all around to forbid renegotiation, but we can chat about that on this list. > A far more important security issue is SSLv2.

What exact concern do you have, and what text would you suggest? Do you propose that we (try to) prohibit or strongly discourage XMPP clients and servers from offering or using SSLv2? That's already covered by Appendix E.2 of RFC 5246 as far as I can see.

The SSL 2.0 protocol is broken [1] and several TLS implementations doesn't implement it at all or disable it by default. I don't believe there is any justification left to be permissive about SSL 2.0 today. Especially in a "modern" protocol like XMPP. RFC 5246 appendix E.2 may lead implementers down the wrong path: it is mostly about SSL 2.0 interoperability. We don't want anyone to be implementing that today. /Simon [1] http://www.gnu.org/software/gnutls/manual/html_node/On-SSL-2-and-older-protocols.html From stpeter@stpeter.im Wed Apr 21 14:38:11 2010 Return-Path: X-Original-To: xmpp@core3.amsl.com Delivered-To: xmpp@core3.amsl.com Received: from localhost (localhost [127.0.0.1]) by core3.amsl.com (Postfix) with ESMTP id 08EA03A683E for ; Wed, 21 Apr 2010 14:38:11 -0700 (PDT) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -1.136 X-Spam-Level: X-Spam-Status: No, score=-1.136 tagged_above=-999 required=5 tests=[AWL=-0.951, BAYES_40=-0.185] Received: from mail.ietf.org ([64.170.98.32]) by localhost (core3.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id C-qZVxsdLT0y for ; Wed, 21 Apr 2010 14:38:10 -0700 (PDT) Received: from stpeter.im (stpeter.im [207.210.219.233]) by core3.amsl.com (Postfix) with ESMTP id AE4F73A6943 for ; Wed, 21 Apr 2010 14:38:08 -0700 (PDT) Received: from dhcp-64-101-72-158.cisco.com (dhcp-64-101-72-158.cisco.com [64.101.72.158]) (Authenticated sender: stpeter) by stpeter.im (Postfix) with ESMTPSA id CDC5640E16 for ; Wed, 21 Apr 2010 15:37:58 -0600 (MDT) Message-ID: <4BCF7035.5010402@stpeter.im> Date: Wed, 21 Apr 2010 15:37:57 -0600 From: Peter Saint-Andre User-Agent: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.1.9) Gecko/20100317 Thunderbird/3.0.4 MIME-Version: 1.0 To: xmpp@ietf.org References: <4BC69B28.8030205@darkrain42.org> <4BC72E01.3060909@stpeter.im> In-Reply-To: <4BC72E01.3060909@stpeter.im> X-Enigmail-Version: 1.0.1 OpenPGP: url=http://www.saint-andre.com/me/stpeter.asc Content-Type: multipart/signed; protocol="application/pkcs7-signature"; micalg=sha1; boundary="------------ms000406010707000908000701" Subject: Re: [xmpp] Special-casing of roster set routing X-BeenThere: xmpp@ietf.org X-Mailman-Version: 2.1.9 Precedence: list List-Id: XMPP Working Group List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 21 Apr 2010 21:38:11 -0000 This is a cryptographically signed message in MIME format. --------------ms000406010707000908000701 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable On 4/15/10 9:17 AM, Peter Saint-Andre wrote: > On 4/14/10 10:50 PM, Paul Aurich wrote: >> As discussed several (wow, actually many) months ago [1], the section = on >> Roster Sets (2.1.4 now) includes the text "The server MUST ignore any >> 'to' address specified on the IQ...". >> >> There seemed to be consensus at the time that the special-casing there= >> was undesirable and that it should be replaced with a note about >> verifying that the sender is authorized to perform the set, but I just= >> noticed that the text is still there in -06. >> >> Have I forgotten some intervening discussion? >=20 > I think the spec editor neglected to fix this. Will do in the next vers= ion. We never settled on text. I suggest the following... ### Note: Traditionally, the IQ stanza of the roster set has included no 'to' address (and special-case checking of such IQ stanzas was encouraged by the predecessor to this specification), with the result all roster sets were sent from an authenticated resource of the account whose roster was being updated. However, the special- casing is no longer encouraged; therefore, if the roster set includes a 'to' address then the server MUST verify that the sender of the roster set is authorized to update the roster, and if not return a error. ### And naturally we'll need to provide examples of that error flow.

In addition, the predecessor to this specification required a server to perform special-case checking of roster set stanzas to ignore the 'to' address; however, this specification has removed that special-casing, which means that a roster set stanza might include a 'to' address other than that of the sender. Therefore, the server MUST verify that the sender of the roster set stanza is authorized to update the roster, and if not return a error. /psa --------------ms050701000302040706020200 Content-Type:

However I'm not convinced we even need to mention the historical part at all (and therefore increase clarity further). Any server MUST verify the sender is authorized to access/modify the roster and that's that, it seems pretty clear and is unrelated to whether the previous spec required servers to ignore 'to' addresses. Thoughts?

Yes, that's that, but it's a change from RFC 3921 so I think it's helpful to call out the change so that client and server developers know that they need to pay special attention to something with such significant security implications. Or would you rather that this go in the security considerations section of rfc3291bis?

3920bis and 3921bis to the IESG by August 2010, I've been working to prepare these specs for working group last call (WGLC). As document editor, here is my current thinking... 1. We need to separate the last calls in time because these specs are so large. 2. Given that 3921bis depends on 3920bis, it makes sense to do 3920bis first, followed by 3921bis. 3. I think that both documents are nearly ready for WGLC. 4. I'm planning to publish version -08 of 3920bis by May 7, which is the version that I expect will be ready for WGLC. To prepare this version I shall thoroughly review the entire spec (including text, examples, schemas, alignment with various RFCs and XEPs referenced in the spec, etc.). Feel free do the same if you're so inclined. :) 5. After WGLC has started on 3920bis, I shall similarly prepare a WGLC-ready version of 3921bis. 6. If all goes well, we can complete WGLC on 3920bis by the end of May and complete WGLC on 3921bis by the end of June, thus leaving July and perhaps part of August for IETF Last Call (yes, I realize that IETF 78 happens in late July, so we'll need to plan around that, too). Feedback is welcome as always.

My only question is: can applications that use a TLS > library easily disable SSL 2.0 support, or are they dependent on the > library? GnuTLS doesn't implement SSL 2.0 at all. I believe SSLv2 has been disabled by default in NSS for some time already. It is easy to disable SSLv2 in OpenSSL (just replace any calls to SSLv2_client_method with a call to TLSv1_client_method). I'd be surprised if it is not easy to disable SSLv2 in Windows too, maybe someone can confirm that? /Simon From stpeter@stpeter.im Wed Apr 28 16:27:02 2010 Return-Path: X-Original-To: xmpp@core3.amsl.com Delivered-To: xmpp@core3.amsl.com Received: from localhost (localhost [127.0.0.1]) by core3.amsl.com (Postfix) with ESMTP id D39AD3A6812 for ; Wed, 28 Apr 2010 16:27:02 -0700 (PDT) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -2.493 X-Spam-Level: X-Spam-Status: No, score=-2.493 tagged_above=-999 required=5 tests=[AWL=0.106, BAYES_00=-2.599] Received: from mail.ietf.org ([64.170.98.32]) by localhost (core3.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id EpLLZhKOhZkl for ; Wed, 28 Apr 2010 16:27:01 -0700 (PDT) Received: from stpeter.im (stpeter.im [207.210.219.233]) by core3.amsl.com (Postfix) with ESMTP id 47FCD3A6358 for ; Wed, 28 Apr 2010 16:27:01 -0700 (PDT) Received: from squire.local (dsl-228-154.dynamic-dsl.frii.net [216.17.228.154]) (Authenticated sender: stpeter) by stpeter.im (Postfix) with ESMTPSA id 6FBAF40E39; Wed, 28 Apr 2010 17:26:47 -0600 (MDT) Message-ID: <4BD8C435.1040600@stpeter.im> Date: Wed, 28 Apr 2010 17:26:45 -0600 From: Peter Saint-Andre User-Agent: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.1.9) Gecko/20100317 Thunderbird/3.0.4 MIME-Version: 1.0 To: Simon Josefsson References: <4BBD0CCF.2040007@stpeter.im> <4BBDF948.3020700@stpeter.im> <4BC6363A.2030404@stpeter.im> <4BCE7C01.4020307@stpeter.im> <87k4s1cnil.fsf@mocca.josefsson.org> <4BD7323F.2080807@stpeter.im> <878w8814h9.fsf@mocca.josefsson.org> In-Reply-To: <878w8814h9.fsf@mocca.josefsson.org> X-Enigmail-Version: 1.0.1 OpenPGP: url=http://www.saint-andre.com/me/stpeter.asc Content-Type: multipart/signed; protocol="application/pkcs7-signature"; micalg=sha1; boundary="------------ms050308050103060302030702" Cc: xmpp@ietf.org Subject: Re: [xmpp] 3920bis-07 X-BeenThere: xmpp@ietf.org X-Mailman-Version: 2.1.9 Precedence: list List-Id: XMPP Working Group List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 28 Apr 2010 23:27:03 -0000 This is a cryptographically signed message in MIME format. --------------ms050308050103060302030702 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable On 4/28/10 12:22 AM, Simon Josefsson wrote: > Peter Saint-Andre writes: >=20 >>>> How is this text? >>>> >>>> Implementations of TLS typically support multiple versions of the= >>>> Transport Layer Security protocol as well as the older Secure Soc= kets >>>> Layer (SSL) protocol.

I don't think that follows. Clients and servers should, however, reject any negotiation of SSLv2 because that is an insecure protocol. I don't believe there are any significant security problems in offering a SSLv2 client hello that ends up negotiating TLSv1? FWIW, GnuTLS supports SSLv2 client hellos in server mode. On the other hand, I don't see the point of sending a SSLv2 client hello if neither client and server will accept SSLv2. But I also don't see a strong reason to forbid that in the specification. One reason to forbid it may be to reduce complexity. /Simon From dave@cridland.net Thu Apr 29 03:22:54 2010 Return-Path: X-Original-To: xmpp@core3.amsl.com Delivered-To: xmpp@core3.amsl.com Received: from localhost (localhost [127.0.0.1]) by core3.amsl.com (Postfix) with ESMTP id 7DDED3A6949 for ; Thu, 29 Apr 2010 03:22:54 -0700 (PDT) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -2.599 X-Spam-Level: X-Spam-Status: No, score=-2.599 tagged_above=-999 required=5 tests=[BAYES_00=-2.599] Received: from mail.ietf.org ([64.170.98.32]) by localhost (core3.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id 7EQBaenjRoP9 for ; Thu, 29 Apr 2010 03:22:52 -0700 (PDT) Received: from peirce.dave.cridland.net (peirce.dave.cridland.net [IPv6:2001:470:1f09:882:2e0:81ff:fe29:d16a]) by core3.amsl.com (Postfix) with ESMTP id BFFB13A684C for ; Thu, 29 Apr 2010 03:22:06 -0700 (PDT) Received: from localhost (localhost.localdomain [127.0.0.1]) by peirce.dave.cridland.net (Postfix) with ESMTP id E506E11680C3; Thu, 29 Apr 2010 11:21:51 +0100 (BST) X-Virus-Scanned: Debian amavisd-new at peirce.dave.cridland.net Received: from peirce.dave.cridland.net ([127.0.0.1]) by localhost (peirce.dave.cridland.net [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id HHJp4p5A2uXL; Thu, 29 Apr 2010 11:21:42 +0100 (BST) Received: from puncture (unknown [IPv6:2001:470:1f09:882:221:85ff:fe3f:1696]) by peirce.dave.cridland.net (Postfix) with ESMTPA id 67A3B11680C2; Thu, 29 Apr 2010 11:21:42 +0100 (BST) References: <4BBD0CCF.2040007@stpeter.im> <4BBDF948.3020700@stpeter.im> <4BC6363A.2030404@stpeter.im> <4BCE7C01.4020307@stpeter.im> <87k4s1cnil.fsf@mocca.josefsson.org> <4BD930FE.2060605@mail.symlynx.com> <87eihypuda.fsf@mocca.josefsson.org> In-Reply-To: <87eihypuda.fsf@mocca.josefsson.org> MIME-Version: 1.0 Message-Id: <19992.1272536502.414283@puncture> Date: Thu, 29 Apr 2010 11:21:42 +0100 From: Dave Cridland To: Simon Josefsson , XMPP Working Group , Philipp Hancke Content-Type: text/plain; delsp="yes"; charset="us-ascii"; format="flowed" Subject: Re: [xmpp] 3920bis-07 X-BeenThere: xmpp@ietf.org X-Mailman-Version: 2.1.9 Precedence: list List-Id: XMPP Working Group List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 29 Apr 2010 10:22:55 -0000 On Thu Apr 29 08:53:37 2010, Simon Josefsson wrote: > On the other hand, I don't see the point of sending a SSLv2 client > hello > if neither client and server will accept SSLv2.

The meat of the document is only 14 pages, so I hope that some XMPP folks will have time to read it -- especially because it is a normative reference from draft-ietf-xmpp-3920bis so we need this to advance before 3920bis can be approved! Please send feedback to the certid@ietf.org list: https://www.ietf.org/mailman/listinfo/certid Thanks!

Another reason might be that if we make a strong statement in the spec about prohibiting SSLv2 then we'll convince more implementations to drop support for it -- and that seems to be the right direction to go in. FYI, in my working copy I currently have the following text: *** 13.8. TLS Versions Implementations of TLS typically support multiple versions of the Transport Layer Security protocol as well as the older Secure Sockets Layer (SSL) protocol. Because of known security vulnerabilities, XMPP servers and clients MUST NOT request or offer SSL 2.0, and MUST close the TCP connection if the other party to an XML stream requests or offers SSL 2.0. See Appendix E.2 of [TLS] for further details. *** --------------ms060202080901070901080306 Content-Type: application/pkcs7-signature; name="smime.p7s" Content-Transfer-Encoding: base64
