wolfSSL version 4.5.0 contains 6 vulnerability fixes: 2 fixes for TLS 1.3, 2 side channel attack mitigations, 1 fix for a potential private key leak in a specific use case, 1 fix for DTLS including those 3 CVEs: - Fix CVE-2020-12457: An issue was discovered in wolfSSL before 4.5.0. It mishandles the change_cipher_spec (CCS) message processing logic for TLS 1.3. If an attacker sends ChangeCipherSpec messages in a crafted way involving more than one in a row, the server becomes stuck in the ProcessReply() loop, i.e., a denial of service. - Fix 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 (e.g., signing with a private key). - Fix CVE-2020-24585: An issue was discovered in the DTLS handshake implementation in wolfSSL before 4.5.0. Clear DTLS application_data messages in epoch 0 do not produce an out-of-order error. Instead, these messages are returned to the application.
