CVE-2019-11247 – Kubernetes kube-apiserver allows access to custom resources via wrong scope
https://notcve.org/view.php?id=CVE-2019-11247
The Kubernetes kube-apiserver mistakenly allows access to a cluster-scoped custom resource if the request is made as if the resource were namespaced. Authorizations for the resource accessed in this manner are enforced using roles and role bindings within the namespace, meaning that a user with access only to a resource in one namespace could create, view update or delete the cluster-scoped resource (according to their namespace role privileges). Kubernetes affected versions include versions prior to 1.13.9, versions prior to 1.14.5, versions prior to 1.15.2, and versions 1.7, 1.8, 1.9, 1.10, 1.11, 1.12. El kube-apiserver de Kubernetes permite por error el acceso a un recurso personalizado de ámbito de clúster si la solicitud se realiza como si el recurso estuviera con espacio de nombres. Las autorizaciones para el recurso al que se tiene acceso de esta manera se aplican mediante roles y enlaces de roles dentro del espacio de nombres, lo que significa que un usuario con acceso solo a un recurso en un espacio de nombres podría crear, ver actualizar o eliminar el recurso de ámbito de clúster (según sus privilegios de rol de espacio de nombres). • https://access.redhat.com/errata/RHBA-2019:2816 https://access.redhat.com/errata/RHBA-2019:2824 https://access.redhat.com/errata/RHSA-2019:2690 https://access.redhat.com/errata/RHSA-2019:2769 https://github.com/kubernetes/kubernetes/issues/80983 https://groups.google.com/d/msg/kubernetes-security-announce/vUtEcSEY6SM/v2ZZxsmtFQAJ https://security.netapp.com/advisory/ntap-20190919-0003 https://access.redhat.com/security/cve/CVE-2019-11247 https://bugzilla.redhat.com/show_bug.cgi?id=1 • CWE-20: Improper Input Validation CWE-284: Improper Access Control CWE-863: Incorrect Authorization •
CVE-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 •
CVE-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 •
CVE-2019-9513 – Some HTTP/2 implementations are vulnerable to resource loops, potentially leading to a denial of service
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 •
CVE-2019-9515 – Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of service
https://notcve.org/view.php?id=CVE-2019-9515
Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of service. The attacker sends a stream of SETTINGS frames to the peer. Since the RFC requires that the peer reply with one acknowledgement per SETTINGS frame, an empty SETTINGS frame is almost equivalent in behavior to a ping. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both. Algunas implementaciones de HTTP / 2 son vulnerables a una inundación de configuraciones, 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://seclists.org/fulldisclosure/2019/Aug/16 https://access.redhat.com/errata/RHSA-2019:2766 https://access.redhat.com/errata/RHSA-2019:2796 https://access.redhat.com/errata/RHSA-2019:2861 https://access.redhat.com/errata/RHSA-2019:2925 https://access.redhat.com/errata/RHSA-2019:2939 https://access.redhat.com/errata/RHSA-2019:2955 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
