Dear Users,
I have released version 5.20 of stunnel.
The ChangeLog entry:
Version 5.20, 2015.07.09, urgency: HIGH * Security bugfixes - OpenSSL DLLs updated to version 1.0.2d. https://www.openssl.org/news/secadv_20150709.txt * New features - poll(2) re-enabled on MacOS X 10.5 and later. - Xcode SDK is automatically used on MacOS X if no other locally installed OpenSSL directory is found. - The SSL library detection algorithm was made a bit smarter. - Warnings about insecure authentication were modified to include the name of the affected service section. - A warning was added to stunnel.init if no pid file was specified in the configuration file (thx to Peter Pentchev). - Optional debugging symbols are included in the Win32 installer. - Documentation updates (closes Debian bug #781669). * Bugfixes - Signal pipe reinitialization added to prevent turning the main accepting thread into a busy wait loop when an external condition breaks the signal pipe. This bug was found to surface on Win32, but other platforms may also be affected. - Fixed removing the disabled taskbar icon. - Generated temporary DH parameters are used for configuration reload instead of the static defaults. - LSB compatibility fixes added to the stunnel.init script (thx to Peter Pentchev). - Fixed the manual page headers (thx to Gleydson Soares).

Thank you Mike for sharing the update! Actually i was trying to install 5.20 on Mac OS using the executable provided by you on website but i am getting the below error while installing. It is giving me error for missing configuration file and when i investigated at the path(/etc/stunnel/stunnel.conf), there was no stunnel folder only.
Also please let me know if i need to install openSSL before installing this executable. Thank you.

Yes, stunnel needs a configuration file to work. It is probably a good time for you to read the fine manual at https://www.stunnel.org/static/stunnel.html
Also please let me know if i need to install openSSL before installing this executable. Thank you.
No, you don't need to install additional OpenSSL library on your OSX.

Thank you Michal for the explanation. Now I am able to load configuration file successfully but I am getting error in creating the connection so I just wanted to know the path where I can see the log file. Also is it possible to change .pem file with this executable? On Jul 13, 2015 1:17 PM, "Michal Trojnara" [email protected] wrote:

Hi Michal,
Thank you for your help! I was able to create connection through stunnel. However i am not sure how to start and stop services using stunnel-5.20b8-osx https://www.stunnel.org/downloads/stunnel-5.20b8-osx executable. I am new to mac OS so i am not aware if there is any standard process for files with this extension. Also this executable works fine on my mac machine but still i wanted to know if there is any requirement for this to work.

Hi Michal ,
I know , i am asking too many questions but i am again stuck. Actually now everything is working fine if i provide absolute path for stunnel.pem in configuration file but as per my requirement , i don't want to be dependent on absolute file path and want to generate it dynamically. but i am not able to understand how to do this.Please help.

The following example illustrates using dynamic configuration files:
#!/bin/bash REMOTE_HOST="www.stunnel.org:443" echo "client script connecting $REMOTE_HOST" stunnel -fd 10 11<&0 <<EOT 10<&0 0<&11 11<&- client=yes connect=$REMOTE_HOST EOT echo "client script finished"

Hi,
I am unable to compile stunnel 5.20 against openssl 1.0.2d (or even 1.0.2c). There a compilation error at some point.
cron.c:151: warning: conflicting types for 'cron_dh_param' cron.c:151: error: static declaration of 'cron_dh_param' follows non-static declaration cron.c:131: error: previous implicit declaration of 'cron_dh_param' was here cron.c: In function 'cron_dh_param':
I'm on on RHEL 5.10. No issues with stunnel 5.19 with either openssl versions.
Thanks.

Version 5.20, 2015.07.09, urgency: HIGH
- Security bugfixes
- OpenSSL DLLs updated to version 1.0.2d. https://www.openssl.org/news/secadv_20150709.txt
- New features
- poll(2) re-enabled on MacOS X 10.5 and later.
- Xcode SDK is automatically used on MacOS X if no other locally installed OpenSSL directory is found.
- The SSL library detection algorithm was made a bit smarter.
- Warnings about insecure authentication were modified to include the name of the affected service section.
- A warning was added to stunnel.init if no pid file was specified in the configuration file (thx to Peter Pentchev).
- Optional debugging symbols are included in the Win32 installer.
- Documentation updates (closes Debian bug #781669).
- Bugfixes
- Signal pipe reinitialization added to prevent turning the main accepting thread into a busy wait loop when an external condition breaks the signal pipe. This bug was found to surface on Win32, but other platforms may also be affected.
- Fixed removing the disabled taskbar icon.
- Generated temporary DH parameters are used for configuration reload instead of the static defaults.
- LSB compatibility fixes added to the stunnel.init script (thx to Peter Pentchev).

Did you configure stunnel with "--with-threads=fork"? It is broken in stunnel 5.20. It is also a bad idea in general.
Otherwise, please send me your config.log.
Mike
Yes I compile with fork.
We have been using that for a very long time. In the 7-8 years range if not a few years more. In the past we decided to use fork to sidestep leaks. We process astronomical numbers of transactions each year on a 24/7 basis and never had any problems.
Can you expand a bit on why it is a bad idea?
Thanks.

A few reasons out of the top of my head:
1. Posix/windows threads are required for session cache, which is a major performance improvement. With fork, stunnel needs to negotiate a new TLS session on each TCP connection with the same peer.
2. Posix/windows threads are required for DH parameter regenerations.
3. Fork not the default compilation option and it doesn't get nearly as much testing as posix/windows threads.
