To the explanation given in bug 352555 comment 15 I would add that, beginning in NSS 3.12.4, there is one additional shared library that has a .chk file produced by shlibsign. The additional chk file is nssdbm3.chk .
Comment 3•15 years ago

(In reply to comment #2) Thanks for that information Nelson. RelEng: Firefox 3.5b4 is using NSS 3.12.3 so we're OK there; mozilla-central has 3.12.4 Beta.

nssdbm3.chk is required for FIPS using NSS 3.12.4, which is Firefox 3.5 and later (mozilla-1.9.2 repo), so that's another file we no longer Authenticode sign (bug 521878).

Comment 7•15 years ago

Let me say some things to assuage your reservations. 1. shlibsign exists for one reason only: to produce "signatures" required to make NSS binaries pass the FIPS 140 tests. 2. The FIPS 140 evaluations are done about every 2 years, on average, and between evaluations, the code is frozen. NSS just went into a code freeze, having just been evaluated. This means that shlibsign won't change until the next time NSS goes into FIPS evaluation, probably 1-2 years from now. 3. Even then, shlibsign doesn't necessarily change for each evaluation. It only changes if/when the FIPS 140 signature requirements change. They haven't changed in a LONG time. They've been the same for several evaluations now. 4. If and when it changes, even if we forget to tell you, you'll find out real quick, because the signatures produced by your (then) old shlibsign will no longer work, and the (then) new NSS will fail to come up in FIPS mode. But the solution will be to simply replace the (then) old shlibsign with the (then) new one. But I think there will be lots of "heads up" about impending FIPS evaluations, so I wouldn't worry about it.

(In reply to comment #6) > shlibsign changing on us is the only reservation I have to this plan. Are there > any ways we could get notified if there are changes in the future ? Sorry for eavesdropping. Sounds like: - you can use any recent-enough shlibsign - shlibsign is built every build - you're worried about whether the shlibsign used is, in fact, recent enough. Why not upload shlibsign with the build, and download it with the build at signing time, and use that?

Comment 10•15 years ago

Guys: i have a changeset which I'm just about ready to add to a bug and try to land (obviously it'll need reviews, etc.). What it will do is cause Firefox (or equivalent) to refuse to load libraries which are not authenticode signed if Firefox is signed. As such, this means that nightlies would have https support until this bug is fixed, but releases would not. Since this seems to be "simply" a matter of copying over shlibsign from a known good release, or from the release we're making. I'd like to see about pushing this eagerly. Nelson's comments seem to indicate we shouldn't be very worried about updates to shlibsign, and I think that we could probably come to an agreement that *if* shlibsign changes interestingly, the NSS team could inform the build team so that they could deal with it. Can we start by trying aki/luser's approach from comment 9.

You can search for shlibsign in the Mozilla source tree for the command line: http://mxr.mozilla.org/mozilla-central/search?string=shlibsign The existing makefile code to look at is here: http://mxr.mozilla.org/mozilla-central/source/toolkit/mozapps/installer/packager.mk#213 The SIGN_NSS command is what you want.

Chris: shlibsign doesn't have a command-line option to verify the generated chk files. I believe the only way to verify the generated chk files are correct is to actually run an NSS-based program (such as Firefox) and see if you can put it in FIPS mode. You can consider doing some sanity checks, such as expected file sizes and the first few bytes (which specify the version of the file format and the type of the public key). Here are the first 12 bytes of a chk file: http://bonsai.mozilla.org/cvsblame.cgi?file=mozilla/security/nss/cmd/shlibsign/shlibsign.c&rev=1.18&mark=1029-1035#1021 Since we don't verify the generated chk files elsewhere, you don't need to verify them.

Check the command's output. signcode sometimes fails even though it returns 0, so I wanted to grab some string that shlibsign outputs and test for that. Also fixed.

You do NOT need to run LiveUpdate to get the fix - this was a back-end change that you should see reflected automatically in the next few hours. Thanks to everyone for alerting us to the problem and for being patient as we worked to fix it. There were some technical irregularities with this Firefox release that caused Norton to make the detection, and we are following up with Mozilla to ensure this doesn't happen again.
Comment 37•14 years ago

LOL. FF 3.6.6 was identical to all previous FF 3.x releases in this regard. I look forward to seeing *ANY* signs that they're "following up" with Mozilla.
Comment 38•14 years ago
|
||
If this particular bug is a longstanding dup, the core issue has popped up before, suggesting the error/cause is recurrent. While we're grateful that Mozilla folks contacted Symantec to expediently resolve the issue (again), this problem speaks of the lack of professional communication and testing between Symantec and Mozilla before update/revision release of browser AND security programs. The impetus to prevent recurrence of similar bugs will probably require Mozilla volunteer bug-stampers to take the initiative, to forge and maintain a strong working liaison with Norton. Nelson's comment rings true: my own experience with the Norton technical support staff was bleak. Three-for-3, I had to figure out and find fixes for OS-NIS conflicts in order to resolve them.
Comment 39•14 years ago
|

FWIW, now that this issue has been brought to my attention I am working directly with Symantec to resolve it so the same issue doesn't happen for the next release. I already work with the AV vendors, notifying them of new releases, etc.
Comment 40•14 years ago
|
||
Nelson, Please take a look at incident 575116 filed by me (and attached to this thread 6 post up), as proof that Symantec is "following up" on the issue. Also we have had a longstanding and highly frustrating discussion with Kevin Needham at Mozilla on this topic, who frequently fails to respond to emails and phone calls. Perhaps we have been speaking to the wrong person, but Symantec is HIGHLY motivated to resolve this problem ASAP.

Jeff, I can be a more responsive contact if needed. I manage Firefox branch releases, so I should probably be in the know in any case. Ping me via email and we'll talk specifics.

Nelson: you're not really helping here, and just putting well intentioned people like Jeff on-tilt. Please stop. Jeff: we know that Adobe's interested, and I'm pretty sure that Kev and Christian have both been and will continue to be responsive. Christian is our branch release manager, and should be included in discussions about upcoming releases. Kev is, as you know, a dedicated friend to all companies that Mozilla interacts with, and can help us figure out how to smooth this process out in the future and how we can try to develop our products in harmony. I'm glad to see that the connections have been made, and this issue will race towards resolution!

Comment 44•14 years ago

Thanks Christian and Mike, I will follow up via email to discuss the details. Also, I'd like to specifically apologize to Kevin for my earlier comments. My characterization was out of line and very unfair to him. We have spoken via email and I hope we have cleared things up.
Comment 45•14 years ago
|
||
Totally wasn't clear, but I meant that I could be a second point of contact if Kev is not available (as people can be at times). I wasn't trying to take the place of Kev, merely provide a clear second communication channel when it comes to releases :-)

Comment 48•14 years ago

AFAICT, it seems very unlikely that we will ever again ship a FIPS-140-validated Mozilla-Authenticode-signed set of NSS libraries with Firefox that requires these *.chk files. My understanding is that the goal is to Authenticode-sign the NSS libraries for FF4.0 release. The *.chk files we will ship with the release will be completely worthless since we're not (and can't) ship a FIPS-validated version of these libraries with the release. We probably need to make some different changes to handle this gracefully, but AFAICT no matter what we do, these *.chk files will not be an issue for FF4.0 release. Please let me know how I can assist you. FWIW, I am in 650 Castro every day.
Comment 49•14 years ago
|
||
Brian, can't? Is this because softoken will be rolled into the same shared lib as PSM in FF 4 (I thought it was too late to do that for FF 4 now) or for some other reason, and if some other, what reason is that?
Comment 50•14 years ago
|
||
I'm also confused by the 'can't'. It clearly doesn't reflect what we where talking about last week. > The *.chk files we will ship with the release will be completely > worthless since we're not (and can't) ship a FIPS-validated version of these > libraries with the release. The *.chk files are not worthless. At this point 4.0 still uses shared libraries, and there has been no changes to softoken and freebl and nssdbm that prevents them from checking their .chk files. Whether or not the libraries are actually validated, the still do their integrity checks when in FIPS mode. Try breaking them in a beta an see how many bug reports you get.:) Even if you remove the FIPS button in FF 4.0 (which would likely cause a support issue), Users who upgrade and already have FIPS on will wind up with a non-functioning browser. > AFAICT no matter what we do, these *.chk files will not be an issue for FF4.0 > release. They actually will be. I don't know why one things it's a problem for authenticode. If authenticode modifies the binaries, just create the .chk files after the authenticode signing. If you need the .chk to replace the authenticode, then it's relatively easy to turn them on always (one simple change to softoken will cause all three to check themselves). bob

Even if we don't ship a FIPS validated version of Softoken with the release, the .chk files aren't worthless because we might later validate the version we ship after we ship it. (Thank you Kai for pointing this out to me.)
Nelson and Robert: my understanding is/was that it won't be acceptable to ship with the currently-validated version of Softoken/FreeBL since we will require a version of Softoken with changes that haven't even been committed yet. I will email you both privately about it.

The checkin-needed keyword attracted me here, but it's not immediately clear which of the two patches needs to be pushed. If the second patch depends on the first, the first needs approval before either can be pushed. Please use the whiteboard to answer these questions for potential volunteer "pushers". Requiring people to look through the comments to figure out this info (if it's even there) means this bug just gets passed over.

Basically the same as before with the small addition of making sure we compress the re-generated chk file if we're working with a mar file. Verification works by calling chktest.exe, which kaie has built for us at http://kuix.de/misc/nss-unofficial-fips-chktest.zip Makefile targets have been updated to get rid of old targets. Don't need to use USE_NEW any more.

We should make sure that the CompanyName property of the executables (in the resource file) is consistent with the signature. See bug 489961. Right now, the resource files contain "Mozilla Foundation" whereas the cert will presumably be issued to "Mozilla Corporation."
