WOLFSSL SECURITY VULNERABILITIES
This page lists known vulnerabilities for the wolfSSL embedded SSL/TLS library, wolfCrypt embedded crypto engine, and other wolfSSL products. Each vulnerability is linked to the description and CVE if available. Please contact us with any questions or concerns.
Known Vulnerabilities
The SSL protocol, along with the more recent TLS 1.2 protocol, are both well documented and under constant scrutiny by the top experts in security and cryptography. SSL was quickly adopted as a standard world wide. SSL and TLS together secure communications between billions of computers, servers, Internet of Things (IoT) devices, and embedded systems. The security provided by an SSL/TLS Library depends on the underlying strength of its cryptography which is used to encrypt communications.
