Vulnerability Fix:
This release of wolfSSL fixes 1 security vulnerability

wolfSSL is cited in the recent ROBOT Attack by Böck, Somorovsky and Young. The paper notes that wolfSSL only gives a weak oracle without a practical attack but this is still a flaw. This release contains a fix for this report. Please note that wolfSSL has static RSA cipher suites disabled by default as of version 3.6.6 because of the lack of perfect forward secrecy. Only users who have explicitly enabled static RSA cipher suites with WOLFSSL_STATIC_RSA and use those suites on a host are affected. More information will be available at https://wolfssl.com/wolfSSL/security/vulnerabilities.php

Implement Security by Design with an Embedded SSL Library
Software and hardware developers are under constant pressure to make their technologies secure by design, rather than only thinking about security as something that gets tacked on later after everything else is complete. Some of the most vulnerable devices end up being embedded systems, such as IoT smart devices, which often have a single purpose but still handle sensitive data. As such, TLS security is something that every device that
