Re: [Bug 551901] Re: likewise-open fails to join Windows 2000 SP4 domain
OK, here's where this stands. We've been discussing on #krbdev, the upstream krb5 IRC channel. We agree that ignoring a MIC token that is an exact copy of the response token is security neutral and it looks like both upstream and I are comfortable making a change to do that even though it seems to go against text in RFC 4178. (I think RFC 4178 is overly conservative here). My argument for why it is security neutral is that an attacker could modify the token in transit and cause the same effect. So, either the protocol is already broken, or this does no harm. What needs to happen now is someone familiar with the MIT SPNEGO code needs to look at the patch and confirm it actually ignores MIC tokens only when MIC tokens are optional. In particular, we want to confirm that if the mechanism supports integrity and a MIC token would be required either through request-mic state or because the acceptor didn't choose tho optimistic mechanism,that a MIC token is still required. It may be relatively easy to argue that's the case--in particular if this patch affects the logic before the code evaluates whether MIC is required, then it's probably fine. I know I'm relatively busy today and I believe the others involved in the discussion so far have been similarly busy. --Sam -- likewise-open fails to join Windows 2000 SP4 domain https://bugs.launchpad.net/bugs/551901 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to krb5 in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
Re: [Bug 551901] Re: likewise-open fails to join Windows 2000 SP4 domain
As best I can tell, the behavior of the patch is explicitly forbidden by RFC 4178 section 5; see II under clause B and C. However, I'll admit that the behavior described in Appendix C does not seem consistent with what I remember for Windows 2000... Perhaps that's only the Windows behavior for krb5 but not NTLM? -- likewise-open fails to join Windows 2000 SP4 domain https://bugs.launchpad.net/bugs/551901 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to krb5 in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
Re: [Bug 551901] Re: likewise-open fails to join Windows 2000 SP4 domain
I don't see a upstream krb5 bug for this issue. I would recommend against applying this patch until someone familiar with the SPNEGO security model and the code has evaluated it. Basically, certain versions of Windows produce bad SPNEGO tokens. It's appropriate to ignore these in some situations spelled out in the RFC, but creates a significant security issue in others. I suspect that this may be OK, but I don't have the spnego state machine in my head now, nor do I have the MIT SPNEGO code in my head now. The easiest way to get comfortable with this patch would be for upstream krb5 to evaluate it: they have been working on the SPNEGO code a lot lately so it would probably require less effort for them. -- likewise-open fails to join Windows 2000 SP4 domain https://bugs.launchpad.net/bugs/551901 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to krb5 in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
