- Fix CVE-2020-10932: fix side channel in ECC code that allowed an adversary with access to precise enough timing and memory access information (typically an untrusted operating system attacking a secure enclave) to fully recover an ECDSA private key. - Fix a potentially remotely exploitable buffer overread in a DTLS client when parsing the Hello Verify Request message. - Fix bug in DTLS handling of new associations with the same parameters (RFC 6347 section 4.2.8): after sending its HelloVerifyRequest, the server would end up with corrupted state and only send invalid records to the client. An attacker able to send forged UDP packets to the server could use that to obtain a Denial of Service. This could only happen when MBEDTLS_SSL_DTLS_CLIENT_PORT_REUSE was enabled in config.h (which it is by default).
