CVSS: 7.8EPSS: 7%CPEs: 39EXPL: 0CVE-2019-9511 – Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service
https://notcve.org/view.php?id=CVE-2019-9511
Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service. The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both. Algunas implementaciones de HTTP / 2 son vulnerables a la manipulación del tamaño de la ventana y la manipulación de priorización de flujo, lo que puede conducir a una denegación de servicio. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00032.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00035.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00014.html https://access.redhat.com/errata/RHSA-2019:2692 https:/ • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •

https://notcve.org/view.php?id=CVE-2019-9512
Some HTTP/2 implementations are vulnerable to ping floods, potentially leading to a denial of service. The attacker sends continual pings to an HTTP/2 peer, causing the peer to build an internal queue of responses. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both. Algunas implementaciones de HTTP / 2 son vulnerables a las inundaciones de ping, lo que puede conducir a una denegación de servicio. El atacante envía pings continuos a un par HTTP / 2, haciendo que el par construya una cola interna de respuestas. • http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00076.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00021.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00032.html http://lists.opensuse.org/opensuse-security-announce/2019-09 • CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2019-9514
Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service. The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both. Algunas implementaciones de HTTP / 2 son vulnerables a una inundación de reinicio, lo que puede conducir a una denegación de servicio. El atacante abre una serie de secuencias y envía una solicitud no válida sobre cada secuencia que debería solicitar una secuencia de tramas RST_STREAM del par. • http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00076.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00021.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00032.html http://lists.opensuse.org/opensuse-security-announce/2019-09 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 7.5EPSS: 1%CPEs: 5EXPL: 0CVE-2019-5737 – nodejs: Insufficient Slowloris fix causing DoS via server.headersTimeout bypass
https://notcve.org/view.php?id=CVE-2019-5737
In Node.js including 6.x before 6.17.0, 8.x before 8.15.1, 10.x before 10.15.2, and 11.x before 11.10.1, an attacker can cause a Denial of Service (DoS) by establishing an HTTP or HTTPS connection in keep-alive mode and by sending headers very slowly. This keeps the connection and associated resources alive for a long period of time. Potential attacks are mitigated by the use of a load balancer or other proxy layer. This vulnerability is an extension of CVE-2018-12121, addressed in November and impacts all active Node.js release lines including 6.x before 6.17.0, 8.x before 8.15.1, 10.x before 10.15.2, and 11.x before 11.10.1. En Node.js, que incluye la versión 6.x en versiones anteriores a la 6.17.0, 8.x en versiones anteriores a la 8.15.1, 10.x en versiones anteriores a la 10.15.2 y 11.x en versiones anteriores a la 11.10.1, un atacante puede provocar una denegación de servicio (DoS) instalando una conexión HTTP o HTTPS en modo keep-alive y enviando encabezados muy lentamente. • http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00041.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00046.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00059.html https://access.redhat.com/errata/RHSA-2019:1821 https://nodejs.org/en/blog/vulnerability/february-2019-security-releases https://security.gentoo.org/glsa/202003-48 https://security.netapp.com/advisory/ntap-20190502-0008 https://access.redhat.com/security/cve/CVE-2019-5737 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •

Node.js: All versions prior to Node.js 6.15.0, 8.14.0, 10.14.0 and 11.3.0: Denial of Service with large HTTP headers: By using a combination of many requests with maximum sized headers (almost 80 KB per connection), and carefully timed completion of the headers, it is possible to cause the HTTP server to abort from heap allocation failure. Attack potential is mitigated by the use of a load balancer or other proxy layer. Node.js: Todas las versiones anteriores a la 6.15.0, 8.14.0, 10.14.0 y 11.3.0: Denegación de servicio (DoS) con cabeceras HTTP grandes. Mediante la combinación de muchas peticiones con cabeceras de tamaño máximo (casi 80 KB por conexión) y al terminar a su debido tiempo las cabeceras, es posible provocar que el servidor HTTP aborte el fallo de asignación de memoria dinámica (heap). El potencial del ataque se ve mitigado por el uso de un balance de carga u otra capa del proxy. • http://www.securityfocus.com/bid/106043 https://access.redhat.com/errata/RHSA-2019:1821 https://access.redhat.com/errata/RHSA-2019:2258 https://access.redhat.com/errata/RHSA-2019:3497 https://nodejs.org/en/blog/vulnerability/november-2018-security-releases https://security.gentoo.org/glsa/202003-48 https://access.redhat.com/security/cve/CVE-2018-12121 https://bugzilla.redhat.com/show_bug.cgi?id=1661002 • CWE-400: Uncontrolled Resource Consumption •
