CVE-2020-24613
wolfSSL before 4.5.0 mishandles TLS 1.3 server data in the WAITCERTCR state, within SanityCheckTls13MsgReceived in tls13.c. This is an incorrect implementation of the TLS 1.3 client state machine. This allows attackers in a privileged network position to completely impersonate any TLS 1.3 servers...
CVE-2020-24613
WolfSSL prior to 4.5.0 mishandles TLS 1.3 server data in the WAIT_CERT_DECL/WAIT_CERT_CERT state within SanityCheckTls13MsgReceived() in tls13.c, representing an incorrect implementation of the TLS 1.3 client state machine. This can enable a privileged network attacker to impersonate TLS 1.3 serv...

CVE-2020-24585
An issue was discovered in the DTLS handshake implementation in wolfSSL before 4.5.0. Clear DTLS applicationdata messages in epoch 0 do not produce an out-of-order error. Instead, these messages are returned to the application...
CVE-2020-15309
An issue was discovered in wolfSSL before 4.5.0, when single precision is not employed. Local attackers can conduct a cache-timing attack against public key operations. These attackers may already have obtained sensitive information if the affected system has been used for private key operations...
