Description

6 years ago
User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/535.1 (KHTML, like Gecko) Ubuntu/11.04 Chromium/14.0.835.202 Chrome/14.0.835.202 Safari/535.1

Steps to reproduce:

I use Firefox 8 with some certificates.
I tested this bug with Firefox 8 build from the mozilla-team beta ubuntu PPA. To help debugging, I added the debug package, and I'll provide backtrace in comments.
I also encountered the same problem with the vanilla build for Linux, on Mageia Linux.
This problem also appears in safe mode.


Actual results:

After some time, Firefox takes 100% cpu on one core, and freezes.
On linux, the firefox windows become grey.


Expected results:

Firefox doesn't freeze.

I also have a workaround for this bug.
I removed some certificates (that were not builtin) and the bug disappeared.
I don't know exactly which certificates caused this bug, but I still have it on one of my machines.

If you explain to me how I can backup my certificates, I can provide them to you.

Some JS code is calling PSM's nsNSSCertificate::GetIssuer, which calls NSS's CERT_FindCertIssuer.  I'll bet that there's a certificate chain loop, and the 
JS code isn't detecting that case by maintaining a maximum chain length count.
NSS's code that builds chains always counts, but this chain building is being 
done by JS code somewhere.

The fact that it reportedly occurs in safe mode suggests that this is PSM code, 
not browser add-on code.

I removed 5 certificates to solve the issue:
- COMODO Cert Authority
- COMODO High-Assurance Secure Server CA
- TBS X509 CA SGC
- UTN Data Corp SGC
- UTN-UserFirst-Hardware

I don't know if you can find them to see which one is the problem....

backtrace on firefox 8b3

Reproduced with Firefox 8b3.
Noted that the 5 certificates I removed have reappeared :(
I don't know if it's related, but it was when I reactivated HTTPS Everywhere addon.

My guess: HTTPS Everywhere has tried to access an https website that has the bad certificate in its https version.

After some tests, the more likely is the "COMODO Cert Authority" certificate.

I'm not sure, but it seems that this is one used by twimg.com.

Still valid in Firefox 9
A potential fix for this issue was pushed to mozilla-inbound today. It will be a day or so before Firefox Nightly has that fix.
Depends on: 764393

Olivier, do you still see this problem when using a current version?

I don't have the certificates to test anymore, closing as WONTFIX, but I would have prefered OLD.

Incomplete is sufficient in situations where the problem cannot be reproduced. For example due to no data or testcase.
