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 on our website at:

https://wolfssl.com/wolfSSL/security/vulnerabilities.php

This release of wolfSSL fixes 1 low level security vulnerability.

Low level fix for a potential DoS attack on a wolfSSL client. Previously a client would accept many warning alert messages without a limit. This fix puts a limit to the number of warning alert messages received and if this limit is reached a fatal error ALERT_COUNT_E is returned. The max number of warning alerts by default is set to 5 and can be adjusted with the macro WOLFSSL_ALERT_COUNT_MAX. Thanks for the report from Tarun Yadav and Koustav Sadhukhan from Defence Research and Development Organization, INDIA.

3 Low level fixes reported by Yueh-Hsun Lin and Peng Li from KNOX Security, Samsung Research America.

Low level fix for memory management with static memory feature enabled. By default static memory is disabled. Thanks to GitHub user hajjihraf for reporting this.

Low level fix for out of bounds write in the function wolfSSL_X509_NAME_get_text_by_NID. This function is not used by TLS or crypto operations but could result in a buffer out of bounds write by one if called explicitly in an application. Discovered by Aleksandar Nikolic of Cisco Talos. http://talosintelligence.com/vulnerability-reports/

Medium level fix for check on certificate signature. There is a case in release versions 3.9.10, 3.10.0 and 3.10.2 where a corrupted signature on a peer certificate would not be properly flagged. Thanks to Wens Lo, James Tsai, Kenny Chang, and Oscar Yang at Castles Technology.
