The Anti-Replay feature in the DTLS implementation in OpenSSL before 1.1.0
mishandles early use of a new epoch number in conjunction with a large sequence number, which allows remote
attackers to cause a denial of service (false-positive packet drops) via spoofed DTLS records, related to
rec_layer_d1.c and ssl3_record.c.
