CVSS: 5.9EPSS: 1%CPEs: 180EXPL: 0CVE-2019-1559 – 0-byte record padding oracle
https://notcve.org/view.php?id=CVE-2019-1559
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. In order for this to be exploitable "non-stitched" ciphersuites must be in use. Stitched ciphersuites are optimised implementations of certain commonly used ciphersuites. Also the application must call SSL_shutdown() twice even if a protocol error has occurred (applications should not do this but some do anyway). • http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00041.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00019.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00046.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00047.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00049.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00080.html http://www.securityfocus.com/bid/107174 https://access. • CWE-203: Observable Discrepancy CWE-325: Missing Cryptographic Step •

CVSS: 7.8EPSS: 74%CPEs: 127EXPL: 0CVE-2018-5390 – Linux kernel versions 4.9+ can be forced to make very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service
https://notcve.org/view.php?id=CVE-2018-5390
Linux kernel versions 4.9+ can be forced to make very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service. El kernel de Linux en versiones 4.9 y siguientes pueden forzarse a realizar llamadas muy caras a tcp_collapse_ofo_queue() y tcp_prune_ofo_queue() para cada paquete entrante, lo que puede conducir a una denegación de servicio. A flaw named SegmentSmack was found in the way the Linux kernel handled specially crafted TCP packets. A remote attacker could use this flaw to trigger time and calculation expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() functions by sending specially modified packets within ongoing TCP sessions which could lead to a CPU saturation and hence a denial of service on the system. Maintaining the denial of service condition requires continuous two-way TCP sessions to a reachable open port, thus the attacks cannot be performed using spoofed IP addresses. • http://www.arubanetworks.com/assets/alert/ARUBA-PSA-2018-004.txt http://www.huawei.com/en/psirt/security-advisories/huawei-sa-20181031-02-linux-en http://www.openwall.com/lists/oss-security/2019/06/28/2 http://www.openwall.com/lists/oss-security/2019/07/06/3 http://www.openwall.com/lists/oss-security/2019/07/06/4 http://www.securityfocus.com/bid/104976 http://www.securitytracker.com/id/1041424 http://www.securitytracker.com/id/1041434 https://access.redhat.co • CWE-400: Uncontrolled Resource Consumption •
