[Patch] Support multiple X509 client certificates with same CN
by Leon Winter 10 Mar '14

10 Mar '14

Hi, currently stunnel uses the X509_STORE_get_by_subject () API call to OpenSSL to retrieve the x509 client certificate in the cert_check () method (located in verify.c) to gather the client certificate from the whitelist by the common name (CN) the client presented during the TLS handshake. It then proceeds to compare both certificates bit by bit. This all works rather fine until the very moment you have more than one client certificate with the same CN. The OpenSSL API call will then return any of the certificates with the provided CN (according to internal logic). Other implementations using OpenSSL were aware of this issue and introduced logic to further iterate over the remaining certificates, retrieving any further with the same CN. See for example function X509_STORE_CTX_get1_issuer () and its comment: http://www.opensource.apple.com/source/OpenSSL/OpenSSL-12/openssl/crypto/x5… I patched stunnel 4.53 and adapted the patch to upstream version 5.00 to behave in similar fashion and can report that with these changes stunnel then also supports multiple client certificates sharing the same CN. Feel free to adapt indention as my patches aim for minimal changed lines. Best regards, Leon Winter

stunnel 5.00 released
by Michal Trojnara 09 Mar '14

09 Mar '14

Dear Users, I have released version 5.00 of stunnel. The ChangeLog entry: stunnel 5.00 disables some features previously enabled by default. Users should review whether the new defaults are appropriate for their particular deployments. Packages maintainers may consider prepending the old defaults for "fips" (if supported by their OpenSSL library), "pid" and "libwrap" to stunnel.conf during automated updates. Version 5.00, 2014.03.06, urgency: HIGH: * Security bugfixes - Added PRNG state update in fork threading (CVE-2014-0016). * New global configuration file defaults - Default "fips" option value is now "no", as FIPS mode is only helpful for compliance, and never for actual security. - Default "pid" is now "", i.e. not to create a pid file at startup. * New service-level configuration file defaults - Default "ciphers" updated to "HIGH:MEDIUM:+3DES:+DH:!aNULL:!SSLv2" due to AlFBPPS attack and bad performance of DH ciphersuites. - Default "libwrap" setting is now "no" to improve performance. * New features - OpenSSL DLLs updated to version 1.0.1f. - zlib DLL updated to version 1.2.8. - autoconf scripts upgraded to version 2.69. - TLS 1.1 and TLS 1.2 are now allowed in the FIPS mode. - New service-level option "redirect" to redirect SSL client connections on authentication failures instead of rejecting them. - New global "engineDefault" configuration file option to control which OpenSSL tasks are delegated to the current engine. Available tasks: ALL, RSA, DSA, ECDH, ECDSA, DH, RAND, CIPHERS, DIGESTS, PKEY, PKEY_CRYPTO, PKEY_ASN1. - New service-level configuration file option "engineId" to select the engine by identifier, e.g. "engineId = capi". - New global configuration file option "log" to control whether to append (the default), or to overwrite log file while (re)opening. - Different taskbar icon colors to indicate the service state. - New global configuration file options "iconIdle", "iconActive", and "iconError" to select status icon on GUI taskbar. - Removed the limit of 63 stunnel.conf sections on Win32 platform. - Installation of a sample certificate was moved to a separate "cert" target in order to allow unattended (e.g. scripted) installations. - Reduced length of the logged thread identifier. It is still based on the OS thread ID, and thus not unique over long periods of time. - Improved readability of error messages printed when stunnel refuses to start due to a critical error. * Bugfixes - LD_PRELOAD Solaris compatibility bug fixed (thx to Norm Jacobs). - CRYPTO_NUM_LOCKS replaced with CRYPTO_num_locks() to improve binary compatibility with diverse builds of OpenSSL (thx to Norm Jacobs). - Corrected round-robin failover behavior under heavy load. - Numerous fixes in the engine support code. - On Win32 platform .rnd file moved from c:\ to the stunnel folder. Home page: https://www.stunnel.org/ Download: https://www.stunnel.org/downloads.html SHA-256 hash for stunnel-5.00.tar.gz: 88986d52a7ef1aff0cc26fc0a9830361c991baba7ee591d5cf1cc8baef75bc13 Best regards, Mike

Weird problem starting stunnel
by Matthew Lunnon 05 Mar '14

05 Mar '14

Hello, Can anyone enlighten me on the following: I have installed stunnel up on my Mac (OS X Lion) and it all runs just fine. When I put this on another machine (OS X Mountain Lion) stunnel refuses to start. I include the output and the stunnel.conf file below. We have some experience of stunnel as we have been using it in both client and server mode on Windows and RedHat for years but none of my colleagues can give me much help here. It looks to me like although stunnel is reporting that it is starting with the correct stunnel.conf file it is actually using something else as: 1) no stunnel.log file is created 2) after successfully seeding the PRNG it seems to be Initializing inetd mode and starting as a service when this should be starting in client mode. (The only way I can get it to do something similar on the machine that works is to remove all the service definitions and put in a line service = SERVICE when it blows up but with a slightly different error about needing an end/connection point (not sure the exact error) and then it fails. Even so in this case it will still create an output log in the correct place) My thoughts are that it might be something to do with the installation process of stunnel that hasn't been followed properly or some kind of permissions issue. Apologies if I am being dim but I am at a bit of a loss to explain what is going on here. I do not have direct access to the second machine and am trying to support it over the phone.

Stunnel - how to make Google App Engine HTTP into HTTPS ?
by Shamun Toha Md 06 Feb '14

06 Feb '14

I have Google App Engine running in HTTP (port tcp 80), which is a daemon based service it execute back-end some python instances. Now all that works over HTTP , TCP 80, and Google App Engine itself do not have any kind of HTTPS setup, it has to be organized externally. Therefore, the biggest problem is now that how can i use stunnel to resolve this problem please? I have already tried following setup and it does not work at all. 1) if the user visit https://www.mysite.com then he hit stunnel accept=443 after that he is connected with connect=80 but user browser change into http:// instead of remaining in https:// . Which make the whole thing not working $ uname -a Linux server2 2.6.32-358.23.2.el6.x86_64 #1 SMP Wed Oct 16 18:37:12 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux $ cat /etc/stunnel/stunnel.conf pid = /stunnel.pid cert=/etc/stunnel/abyhu.crt CAfile=/etc/stunnel/abyhu.ca key=/etc/stunnel/abyhu.key sslVersion = all ;socket = l:TCP_NODELAY=1 ;socket = r:TCP_NODELAY=1 client=no debug = 7 output = /var/log/stunnel.log [SSL] accept=443 connect=80 TIMEOUTclose = 0 My goal is: when user visit https://www.mysite.com it remain as https not become http:// then it is not solving the problem cause Google app engine do not have HTTPS Thank you. Best regards

Specifying a username and password
by Allen Crist 29 Jan '14

29 Jan '14

I have a scanner that only has an smtp address and port #. There is no option to specify a username and password. Is there a way to configure STunnel to assist with this?

Filename is not cached for later editing
by Javier 24 Jan '14

24 Jan '14

Hi, Scenario in Windows. I found today that, when you specify a configuration file different from the standard file name, you can't edit it through "Configuration>Edit stunnel.conf". Stunnel tries to edit stunnel.conf, and, if not found, creates a new one through notepad. This doesn't affect to the reload function, where the configuration file specified is used for reload. Also, this is not important, because in most cases is used the default file name, but maybe could be implemented the ability to change those menu options to display the current configuration file name used instead the standard. Let's say we use a configuration file named xxx.conf. The menu may change to "Edit xxx.conf" and "Reload xxx.conf" instead "Edit stunnel.conf" and "Reload stunnel.conf". This may be interesting for when we have several services installed and identify them better. Regards.

Additional certificate (like openssl s_server -dkey/-dcert)
by Lapo Luchini 24 Jan '14

24 Jan '14

Is it possible to configure STunnel to support "additional" certificate like OpenSSL s_Server's -dkey/-dcert parameters, in order to support ECDSA in addition to RSA on the same connection? -- Lapo Luchini - http://lapo.it/ “Two can keep a secret if one is dead.” (anonymous)

SSL communication is unestablishable by stunnel.

OCSP Responders in AIA extension
by Ender Erel 22 Jan '14

22 Jan '14

Hi All, Does stunnel check the OCSP responders found in a certificate's AIA field? I am asking this because in the following e-mail from back 2008, the sender mentions a patch that implements this functionality. The patch is included with the mail but I don't think it is included in the later versions of stunnel. Does this mean OCSP responders inside a certificate are ignored? I also want to ask another thing. When using verify = 3 in client mode, which file is used to check the received certificate? Is it the CAfile? If so, would it work like this: - I manually opened a connection to a server outside stunnel, downloaded the server's certificate, and closed the connection. - I saved this certificate to a file, and wrote the path of this file in the stunnel configuration file (CAfile = /mycerts/tmpcert.pem,verify=3). - I started stunnel and initiated a connection to the server. Would the connection be successful? Would it be the right way to use verify=3? Kind Regards, Ender Erel

disabling compression
by James Bardin 22 Jan '14

22 Jan '14

Hi, The stunnel man page states that compression is off by default, but It seems that is no longer the case. (the changelog states that version 4.5.1 sets compression as "not disabled by default") The config options don't seem to accept any parameters to disable compression. Is there any way to disable it via openssl options? Thanks! -jim

Question about 'delay = yes' and DNS cache
by John Chow 16 Jan '14

16 Jan '14

Hey Everyone, I have a question about the *delay = yes* config flag and whether or not it caches the resolved IP after the initial connection? To give context, I want my load balancer (Haproxy) to forward requests to an app on Heroku, and I'm using stunnel on my LB box to proxy to Heroku via HTTPS. Since the IP for my app's endpoint could potentially change (60s DNS TTL), stunnel caching resolved IPs would be a problem. Thanks, John -- John Chow Software Engineer Fundly

Hi I have been searching through google, and from the result there, it should be possible to install stunnel silently on Windows using a /S switch.... I have tried this with the stunnel-4.56-installer.exe package - but it doesn't seem to work..... Can anyone tell me how to install stunnel silently - with no user interaction at all ? Regards /Brian

Multiple OCPSs

Hi All, We want to use multiple OCSP servers, but the way I see it we can specify only one OCSP server in the configuration file. Is there any other way to do this? Regards, Ender

Extra listeneres running that loop back to each other.
by Keith Knapp 15 Jan '14

15 Jan '14

Hi, Every time I start stunnel two unexplainable things happen. 1. The settings in my .conf file are not implemented and I have checked them syntactically. 2. I use TCPView and can see two established connections associated with the stunnel process, but they are *not* in my .conf file - Every time I restart the service the two connections reappear but are associated with different ports. - Furthermore the connections loop back on each other; meaning that the remote port of the one connection is the local port of the other connection (and vice-versa). - Are these supposed to be there? I have done a fresh install of the newest version of stunnel. Keith

It's ok using mode fork rather than pthread. Regards, FWX.
