CVSS: 7.5EPSS: 0%CPEs: 36EXPL: 0CVE-2019-20388 – libxml2: memory leak in xmlSchemaPreRun in xmlschemas.c
https://notcve.org/view.php?id=CVE-2019-20388
21 Jan 2020 — xmlSchemaPreRun in xmlschemas.c in libxml2 2.9.10 allows an xmlSchemaValidateStream memory leak. La función xmlSchemaPreRun en el archivo xmlschemas.c en libxml2 versión 2.9.10, permite una pérdida de memoria de la función xmlSchemaValidateStream. A memory leak was found in the xmlSchemaValidateStream function of libxml2. Applications that use this library may be vulnerable to memory not being freed leading to a denial of service. System availability is the highest threat from this vulnerability. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00047.html • CWE-401: Missing Release of Memory after Effective Lifetime •
CVSS: 5.9EPSS: 5%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.

21 Sep 2016 — The TLS protocol 1.2 and earlier supports the rsa_fixed_dh, dss_fixed_dh, rsa_fixed_ecdh, and ecdsa_fixed_ecdh values for ClientCertificateType but does not directly document the ability to compute the master secret in certain situations with a client secret key and server public key but not a server secret key, which makes it easier for man-in-the-middle attackers to spoof TLS servers by leveraging knowledge of the secret key for an arbitrary installed client X.509 certificate, aka the "Key Compromise Impe... • http://twitter.com/matthew_d_green/statuses/630908726950674433 • CWE-295: Improper Certificate Validation •
