We are using iOS SDK for zoom calls in our app.  
Recently, one of the security scan indicated that framework is using openssl version 1.0.2r.

Version: [v4.4.56624.1028]

Is there any openssl library is used in framework? If so, would you please supply change logs for each build version’s openssl version number?

Also, what is the TLS version iOS SDK using? Based on Wireshark capture it starts as TLSv1.

Thanks for the reply. Unfortunately, I do not have any updates yet. May I inquire are you facing any issues with OpenSSL and our SDK?

Thanks!

Hi,

It is iOS SDK. All we want to know is “OpenSSL version used in latest zoom iOS SDK”. Security scan requires certain OpenSSL versions…

Another finding is that the security scan indicated that framework is using openssl version 1.0.2d.

Hi okan,

Thanks for the reply. After consulting with the team, unfortunately we are not able to publicly reveal this information. Pardon the inconvenience. If you are facing any particular issues caused by this, please let me know and I will work with the engineering team to fix them. Thank you for your understanding.

Thanks!

Hi, Carson,  
This is Bin - Okan’s co-worker.  
Thanks for your email to Okan that ZOOM SDK has update with Open SSL Rev 1.0.2u. However since we initially contacted ZOOM in December 2019, there are quite changes. Version 1.0.2u is already out of support since January 2020 and is no longer receiving updates. From our last submission of our iOS app, FirstNet stated that version 1.1.1d is the new requirement. Please advice.  
Thanks!

</div>

Hi Bin,

Thanks for the reply. Based on the information shown on OpenSSL’s website, 1.0.2u is newer than 1.1.1d(Updated date) , and it has addressed the known vulnerabilities found in the 1.0.2 versions.

 ![Screen Shot 2020-02-19 at 1.11.57 PM](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/7/7dcbda7b3f5a765e15640fe55e780cff46d09c8c.png)

If you could provide the links or the news articles saying that the 1.0.2u would be out of support and no longer receiving updates, it would be very helpful for us to re-evaluate this upgrade. (I found this article: [https://www.openssl.org/blog/blog/2019/11/07/3.0-update/](https://www.openssl.org/blog/blog/2019/11/07/3.0-update/), please verify)

Thanks!

Hi Carson:  
Thanks for your info. Here is the original reply from FirstNet Security team in quota:  
"FYI, version 1.0.2u is already out of support since January 2020 and is no longer receiving updates. Support is only for those that are premium support customers. See here… [https://www.openssl.org/news/vulnerabilities-1.0.2.html](https://www.openssl.org/news/vulnerabilities-1.0.2.html) "  
Please advise.

Hello Carson:

Is there any update on the availability of Zoom iOS SDK with latest OpenSSL version. This is stopping us to get approval of our app from FirstNet security review.

The FirstNet requires to have OpenSSL version of at least 1.1.1e or later.

Thanks

Hi [asharma](https://devforum.zoom.us/u/asharma),

Thanks for the reply. The upgrade process is still ongoing. It is a major version upgrade from 1.0.2 to 1.1.1 so it takes sometime. I will try to escalate this and keep you updated.

Thanks!
