CVSS: 5.9EPSS: 6%CPEs: 180EXPL: 0CVE-2019-1559 – 0-byte record padding oracle
https://notcve.org/view.php?id=CVE-2019-1559
26 Feb 2019 — If an application encounters a fatal protocol error and then calls SSL_shutdown() twice (once to send a close_notify, and once to receive one) then OpenSSL can respond differently to the calling application if a 0 byte record is received with invalid padding compared to if a 0 byte record is received with an invalid MAC. If the application then behaves differently based on that in a way that is detectable to the remote peer, then this amounts to a padding oracle that could be used to decrypt data.

CVSS: 7.5EPSS: 60%CPEs: 18EXPL: 4CVE-2017-3730 – Bad (EC)DHE parameters cause a client crash
https://notcve.org/view.php?id=CVE-2017-3730
26 Jan 2017 — In OpenSSL 1.1.0 before 1.1.0d, if a malicious server supplies bad parameters for a DHE or ECDHE key exchange then this can result in the client attempting to dereference a NULL pointer leading to a client crash. This could be exploited in a Denial of Service attack. En OpenSSL versión 1.1.0 anterior a 1.1.0d, si un servidor malicioso suministra parámetros incorrectos para un intercambio de claves DHE o ECDHE, entonces esto puede resultar en que el cliente intente desreferenciar un puntero NULL que conduce ... • https://packetstorm.news/files/id/140804 • CWE-476: NULL Pointer Dereference •
