Apache Traffic Server is vulnerable to HTTP/2 setting flood attacks. Earlier versions of Apache Traffic Server didn't limit the number of setting frames sent from the client using the HTTP/2 protocol. Users should upgrade to Apache Traffic Server 7.1.7, 8.0.4, or later versions. Apache Traffic Server es vulnerable a los ataques de inundación de la configuración HTTP/2. Las versiones anteriores de Apache Traffic Server no limitaban el número de tramas de configuración enviadas desde el cliente utilizando el protocolo HTTP/2. • https://lists.apache.org/thread.html/392108390cef48af647a2e47b7fd5380e050e35ae8d1aa2030254c04%40%3Cusers.trafficserver.apache.org%3E https://lists.apache.org/thread.html/ad3d01e767199c1aed8033bb6b3f5bf98c011c7c536f07a5d34b3c19%40%3Cannounce.trafficserver.apache.org%3E https://lists.apache.org/thread.html/bde52309316ae798186d783a5e29f4ad1527f61c9219a289d0eee0a7%40%3Cdev.trafficserver.apache.org%3E • CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 7.8EPSS: 1%CPEs: 35EXPL: 0CVE-2019-9518 – Some HTTP/2 implementations are vulnerable to a flood of empty frames, potentially leading to a denial of service
https://notcve.org/view.php?id=CVE-2019-9518
Some HTTP/2 implementations are vulnerable to a flood of empty frames, potentially leading to a denial of service. The attacker sends a stream of frames with an empty payload and without the end-of-stream flag. These frames can be DATA, HEADERS, CONTINUATION and/or PUSH_PROMISE. The peer spends time processing each frame disproportionate to attack bandwidth. This can consume excess CPU. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00032.html http://seclists.org/fulldisclosure/2019/Aug/16 https://access.redhat.com/errata/RHSA-2019:2925 https://access.redhat.com/errata/RHSA-2019:2939 https://access.redhat.com/errata/RHSA-2019:2955 https://access.redhat.com/errata/RHSA-2019:3892 https://access.redhat.com/errata/RHSA-2019:4352 https://access.redhat.com/errata/RHSA-2020:0727 • 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 •
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 •
