CVSS: 7.5EPSS: 0%CPEs: 39EXPL: 0CVE-2019-9516 – Some HTTP/2 implementations are vulnerable to a header leak, potentially leading to a denial of service
https://notcve.org/view.php?id=CVE-2019-9516
Some HTTP/2 implementations are vulnerable to a header leak, potentially leading to a denial of service. The attacker sends a stream of headers with a 0-length header name and 0-length header value, optionally Huffman encoded into 1-byte or greater headers. Some implementations allocate memory for these headers and keep the allocation alive until the session dies. This can consume excess memory. Algunas implementaciones de HTTP / 2 son vulnerables a una fuga de encabezado, 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/msg00014.html http://seclists.org/fulldisclosure/2019/Aug/16 https://access.redhat.com/errata/RHSA-2019:2745 https://access.redhat.com/errata/RHSA-2019:2746 https://access.redhat.com/errata/RHSA-2019:2775 https&# • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •

https://notcve.org/view.php?id=CVE-2019-9513
Some HTTP/2 implementations are vulnerable to resource loops, potentially leading to a denial of service. The attacker creates multiple request streams and continually shuffles the priority of the streams in a way that causes substantial churn to the priority tree. This can consume excess CPU. Algunas implementaciones de HTTP / 2 son vulnerables a los bucles de recursos, lo que puede conducir a una denegación de servicio. El atacante crea múltiples flujos de solicitud y baraja continuamente la prioridad de los flujos de una manera que provoca un cambio considerable en el árbol de prioridad. • 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 •
CVSS: 7.8EPSS: 9%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 •
CVSS: 8.2EPSS: 0%CPEs: 10EXPL: 0CVE-2018-16845 – nginx: Denial of service and memory disclosure via mp4 module
https://notcve.org/view.php?id=CVE-2018-16845
nginx before versions 1.15.6, 1.14.1 has a vulnerability in the ngx_http_mp4_module, which might allow an attacker to cause infinite loop in a worker process, cause a worker process crash, or might result in worker process memory disclosure by using a specially crafted mp4 file. The issue only affects nginx if it is built with the ngx_http_mp4_module (the module is not built by default) and the .mp4. directive is used in the configuration file. Further, the attack is only possible if an attacker is able to trigger processing of a specially crafted mp4 file with the ngx_http_mp4_module. nginx en versiones anteriores a la 1.15.6 y 1.14.1 tiene una vulnerabilidad en ngx_http_mp4_module, que podría permitir que un atacante provoque un bucle infinito en un proceso worker o resulte en la divulgación de la memoria del proceso mediante el uso de un archivo mp4 especialmente manipulado. El problema solo afecta a nginx si está incluido con ngx_http_mp4_module (el módulo no está incluido por defecto) y se emplea la directiva .mp4 en el archivo de configuración. Además, el atacante solo es posible si un atacante puede desencadenar el procesado de un archivo mp4 especialmente manipulado con ngx_http_mp4_module. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00035.html http://mailman.nginx.org/pipermail/nginx-announce/2018/000221.html http://seclists.org/fulldisclosure/2021/Sep/36 http://www.securityfocus.com/bid/105868 http://www.securitytracker.com/id/1042039 https://access.redhat.com/errata/RHSA-2018:3652 https://access.redhat.com/errata/RHSA-2018:3653 https://access.redhat.com/errata/RHSA-2018:3680 https://access.redhat.com/errata/RHSA-2018:3681 https://bugzilla.r • CWE-201: Insertion of Sensitive Information Into Sent Data CWE-400: Uncontrolled Resource Consumption CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
