157955 - [OCSP] [FIREWALL] SSL Error -5933 at given site

Status: VERIFIED DUPLICATE of bug 111384

(Core Graveyard :: Security: UI, defect, P3)

Description

[Alon Altman]

When trying to access given URL (credit-card company), mozilla pauses for a few
seconds and then outputs:

"Error establishing an encrypted connection to secure.cal-online.co.il error
code -5933"

Tracking the source code, it seems to be called from
http://lxr.mozilla.org/mozilla/source/security/manager/ssl/src/nsNSSIOLayer.cpp#1293
because this is the only place it's not checked to be an SEC or SSL error (which
it's not).

I can always reproduce this bug, but IIRC the site works fine on Linux.

I'm using Mozilla 2002061104 (1.1 alpha)

Confirmed also under Linux 2002052918 (Mozilla 1.0)

Comment 3

[John Unruh]

Works for me. There were problems with the Verisign Class 3 CA in older builds, 
but this works now. Reporter, please try again with today's build.

Comment 4

[Alon Altman]

Rechecked on today's build on WinNT 2002071708, same result.

Also, the browser does not load any pages, and will not close after visiting the
site. Requires killing the browser from task manager. Potential DoS?

Comment 5

[Alon Altman]

Update: this fails with paypal.com as well, but sourceforge.net works ok.

This is probably due to some kind of firewall installed here (technion.ac.il).

Comment 6

[Alon Altman]

Attachment: Packet dump of problematic connection to PayPal

I have added a tcpdump output (cut down) of the failed connection to PayPal.

Comment 7

[John Unruh]

Reporter, can you try a new profile, or if you are not using personal 
certificates for client authentication or secure email, delete the *.db files 
in your profile, restart the browser and try the site again?

Comment 8

[Alon Altman]

Deleted *.db in my profile, still happening with www.paypal.com.

Comment 9

[John Unruh]

Do you have FIPS enabled or OCSP on?

[Kai Engert (:KaiE:)]

Looking at the packet dump, I can see that besides a connection to
www.paypal.com:443 there is also a connection attempt to ocsp.verisign.com:80

That means you have OCSP turned on. As a workaround, you can disable OCSP
(edit/prefs/privacy/validation).

You say there is a firewall at your place. Do you have to use a proxy to connect
to remote sites? Should a connection from your machine to ocsp.verisign.com:80
go through without using a proxy?

(Note to others looking at the bug: You can read the attachment using "tcpdump
-r filename -n")

Comment 11

[Alon Altman]

Yes, my connection requires a firewall for non-israelli sites for port 80, and
yes one was configured (I cut the HTTP access to the firewall from the packet dump).

Also, for reading the dump, I recommend ethereal from http://www.ethereal.com
(open source). I'll check the recommendations in comment 9 as soon as I'm back
to the office (where I have these problems).

Comment 12

[Kai Engert (:KaiE:)]

Ok, if you need a proxy, then it will not work at the moment. Please see the
duplicate bug.
