SOCKS connection to the IPv4 loopback rejected.
by Robert de Bath 15 Apr '17

15 Apr '17

Hi everyone, How do I get rid of this message? I have a stunnel server setup on a remote machine using the socks protocol. I use two keys plus the certificates and a private CA to protect the SSL link. On a local machine I have an stunnel client running without a protocol option set. If I try to make a socks connection to an interface IP of the remote server it works perfectly, bypassing the intervening firewalls through the protected tunnel. But the interface IP changes and I only want to allow connections to the remote server through the tunnel. I could setup traditional tunnels, but while one of the services (remote desktop to the Windows server) is constant the others are dynamically configurable. I have even considered using SNI to distinguish the incoming connections to the various services but while this allows there to be just one tunnel port it will still need a remote reconfiguration of stunnel every time a service port is added or removed. The best way to express this limit is that the socks server should ONLY connect to localhost; but it's "rejected". In actual operation I will probably need to allow the local network too which will probably be an rfc1597 address. Looking at the source it appears that this condition is hard coded into the "validate" function so my question becomes: can you please remove this or add a flag to turn it off? -- Robert de Bath robert(a)tvisiontech.co.uk

Configure Error
by Kenway Ng 12 Apr '17

12 Apr '17

Hi I am running into an issue when I go into the src directory and I run the configure command, I get configure: error: Could not find your TLS library installation dir Use --with-ssl option to fix this problem I am trying to upgrade our version of stunnel. Our SME left and now I am trying to upgrade stunnel to fix a vulnerability . I am being told to use TLS1.1 or higher Here is our current version of stunnel $ ./stunnel -version stunnel 4.15 on x86_64-redhat-linux-gnu with OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008 Threading:PTHREAD SSL:ENGINE Sockets:POLL,IPv6 Auth:LIBWRAP Any help would be appreciated.

PSK, verifying the client
by Mike 05 Apr '17

05 Apr '17

Is it possible to verify the client using PSK? On the stunnel server I specify a PSKsecrets file with two lines in it, one for client01 and one for client02. The secret is about 36 characters long. On a client, I have a similar PSKsecrets file, but only containing the client01 line. Now, if I try to connect with, say, a client03, i.e., any client that does not have a matching line in the server's PSKsecrets file, how can I assure that the client connection will be rejected? What I'd like to see would be the following: any client that tries to connect, and does not present a PSK that is present in the server's PSKsecrets file, then that client's connection request is rejected, with an appropriate message logged. Can I do that with the current stunnel? thx.

Scan to email failure: RapbianPi3 to Office365
by Graeme Ellisson 03 Apr '17

03 Apr '17

Hi. I recently bought a Pi3 and have loaded Raspbian with Doobs (Previously I had this running faultlessly under a Windows Server for my Canon multi function printer that does not support SSL/TLS but only authentication). After about 8 attempts to get Stunnel4 working (there doesn't seem to be a later version to install via the command line) I eventually found that Stunnel4 works fine as long as one doesn't update Dabian from the initial Doobs install. So, I now have the service running and listening on port 25 with the following config file: debug=7 output=/etc/stunnel/stunnel.log client=yes options=NO_SSLv2 (I added this last night after reading a blog) [SMTP OUT] sslVersion=TLSv1 (I added this last night after reading a blog) protocol=smtp accept=25 connect=smtp.office365.com:587 On restarting the service I see the following which looks okay

Stunnel Version Vulnerability-Currently using 5.04
by Tracy Drake - IQGC-C 28 Mar '17

28 Mar '17

Hello Stunnel Users Forum! I wonder if anyone may have suggestions of what, if anything can be done to surmount a reported vulnerability for Stunnel versions prior to 5.34. I have limited savvy in this arena so please excuse this "Stunnel for Dummies" question. The following statements surfaced in a "security vulnerabilities" report... The version of stunnel installed on the remote host is 4.46 or later but prior to 5.34. It is, therefore, affected by a security bypass vulnerability related to the validation of level 4 peer certificates. An unauthenticated, remote attacker can exploit this to have an impact on confidentiality, integrity, and/or availability. No other details are available. I am of the mind that perhaps an entry in Stunnel.conf until we can deploy an upgrade? Thanks in advance for any feedback! Upgrade to stunnel version 5.34 or later. -- Tracy Drake CSM Senior Consultant GSA-FAS CAMEO Contractor URSA & INFOConnect Support & Training Team Lead 704-987-1211 tracy.drake(a)gsa.gov

stunnel public private key authentication like ssh
by Michael Power 23 Mar '17

23 Mar '17

Is there a way to configure stunnel just to check the public key of the provided certificate? I want authentication between the server and the client to take place by public key only, no PKI just like ssh. Is this possible? Is this verify level 4, or does that still check the CN against the host that I am connecting to? Michael Power

update stunnel with engine pkcs11
by Heinsbroek, Peter 20 Mar '17

20 Mar '17

Hallo, I’m a newbee in C programming. I have to upgrade stunnel 5.31 with engine_pkcs11 (0.1.8) for windows to the latest versions. (5.40 & 0.2.2) My engine_pkcs.c contains an subroutine my_get_pin (see attachment line 707) that reads a pin from a file in the windows folder. After reading it ,it transforms the pin to hexadecimal, if not already done, and writes it back in the file. After adjusting the new source it compiles without errors, but when executing it doesn’t work anymore. I also attached the old engine_pkcs11.c as we used it. Can someone help me with this problem. After compairing the old and new source I noticed that there have been major improvements to the source With regards, Peter Heinsbroek Application manager NT / SQL20xx Tel. +31 (0)88 265 9869 Mob. +31 6 5375 3244 Werner von Siemensstraat 3 2712 PN Zoetermeer, Nederland Org. unit PS Central Fin Services Unit 02 SI NL Email peter.heinsbroek(a)atos.net<mailto:peter.heinsbroek@atos.netm> Web www.nl.atos.net<UrlBlockedError.aspx> Atos IT Solutions and Services B.V.

Fwd: Stunnel Performance strangeness
by Scott McKeown 10 Mar '17

10 Mar '17

Hi All, We have been doing some throughput testing and are wondering of you can help explain some of the results we have been getting. We are trying to establish the maximum number of handshakes per second our appliances can do when using Stunnel. Our tests have been done on a 4 core Intel(R) Xeon(R) CPU E3-1230 v5 @ 3.40GHz machine with 8Gb ram. Using stunnel 5.33 openssl 1.0.2j (We use stunnel 5.33 here, but this was also tested with stunnel 5.40 and we got the same issue) Stunnel was compiled with - ./configure --enable-fips --enable-ipv6 --with-threads=pthread --sysconfdir=/etc --with-ssl=/usr/src/built/OpenSSL_1_0_2j-no_march/usr/local/ --disable-libwrap --disable-systemd I was using a python script of my own design for load testing when I noticed the problem we then switched to an open source package called vegeta https://github.com/tsenart/vegeta the command I was using to run it was - echo "GET https://10.10.10.10:443" | ./vegeta attack -workers=30 -rate=3000 -duration=300s -insecure > test.out We are essentially seeing a degradation in throughput at a fixed point in time. I am seeing the problem when using 3000 transactions per second. We are doing https gets through stunnel to a http backend, 1 transaction is an ssl handshake the http get and waiting for the response. Interestingly if I try 5.06 it works fine I get a smooth constant loading. Please take a look at 30worker3000rate5.33-300s.png where you can see after about 55 seconds there is a jump in latency. I get the same issue if I run the test with 2000 transactions. Please see 30worker20005.33-700s.png but with the lower transaction rate the issue takes longer to rear its head. The issue doesnt happen if I run the test with 3000 transaction using 5.06. Please see 30worker3000rate5.06-300s.png >From looking at the graphs our thoughts were that we were hitting some sort of cache limit and used that as a starting point. We have taken a look at the code changes between versions we know were working and the problematic version and the main thing that stands out is the changes to the leak detection. Previously this was partially based on the number of clients but has been changed to use the sections. This led to the decision to try a different limit value and found the number of connections we saw before seeing an issue corresponds to the change of the limit value. We think we have identified the code that is causing the problem/doing something funny it was added in 5.33 NOEXPORT long leak_threshold() { long limit; limit=10000*((int)number_of_sections+1); #ifndef USE_FORK limit+=100*num_clients; #endif return limit; } its src/str.c when increasing the limit number so limit=10000*((int)number_of_sections+1) to limit=20000*((int)number_of_sections+1) This still results in an increase in response time but at a later time in the test, please see 30worker3000rate5.33-ben-highlimit.png Interestingly once I end up in this state I am stuck with high latencies until I restart stunnel. (The box I am testing on was left over night to make sure its not any hanging tcp connections or anything like that) I must admit we are at the limit of our C understanding and your imput would be welcomed. -- With Kind Regards.

Segfault after connecting
by Andrew Culver 23 Feb '17

23 Feb '17

I had my stunnel instance working as expected last week. Since then I've moved the server behind a load balancer, which is doing regular health checks (opens a tcp connection, then disconnects) to see that stunnel is up. I don't believe the health checks are a problem, but they're the only change I've made since I had stunnel working. I can see the health checks connecting and disconnecting. However when I open a new connection, either by telnet or by: openssl s_client -connect mtar.uwo.ca:587 -starttls smtp ... stunnel says it fails to verify the server certificate, then seg faults. I'm running stunnel 5.40 and I'm having the same problem on 2 different servers running openssl 1.1.0d and 1.1.0e. Here's my config: [root@mtar1 stunnel]# egrep -v '^;|^ *$' stunnel.conf ; Sample stunnel configuration file for Unix by Michal Trojnara 2002-2017 setuid = stunnel setgid = stunnel pid = /usr/local/var/run/stunnel/stunnel.pid foreground = yes debug = debug [uwo2local] accept = 587 cert = /usr/local/etc/stunnel/mtar-withprivatekey.pem connect = 20587 protocol = smtp [local2o365] client = yes accept = 127.0.0.1:20587 connect = smtp.office365.com:587 checkHost = smtp.office365.com verifyChain = yes CApath = /etc/ssl/certs OCSPaia = yes protocol = smtp Here's my debug log: The health checks are from 172.18.58.5 and my test connection which leads to the seg fault is from 129.100.6.17.
