CVSS: 8.1EPSS: 0%CPEs: 1EXPL: 0CVE-2021-20198 – openshift/installer: Bootstrap nodes allow anonymous authentication on kubelet port 10250
https://notcve.org/view.php?id=CVE-2021-20198
A flaw was found in the OpenShift Installer before version v0.9.0-master.0.20210125200451-95101da940b0. During installation of OpenShift Container Platform 4 clusters, bootstrap nodes are provisioned with anonymous authentication enabled on kubelet port 10250. A remote attacker able to reach this port during installation can make unauthenticated `/exec` requests to execute arbitrary commands within running containers. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. Se encontró un fallo en el instalador de OpenShift versiones anteriores a v0.9.0-master.0.20210125200451-95101da940b0. • https://bugzilla.redhat.com/show_bug.cgi?id=1920764 https://access.redhat.com/security/cve/CVE-2021-20198 • CWE-306: Missing Authentication for Critical Function •
CVSS: 8.8EPSS: 0%CPEs: 3EXPL: 0CVE-2021-3344 – openshift/builder: privilege escalation during container image builds via mounted secrets
https://notcve.org/view.php?id=CVE-2021-3344
A privilege escalation flaw was found in OpenShift builder. During build time, credentials outside the build context are automatically mounted into the container image under construction. An OpenShift user, able to execute code during build time inside this container can re-use the credentials to overwrite arbitrary container images in internal registries and/or escalate their privileges. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. This affects github.com/openshift/builder v0.0.0-20210125201112-7901cb396121 and before. • https://bugzilla.redhat.com/show_bug.cgi?id=1921450 https://access.redhat.com/security/cve/CVE-2021-3344 • CWE-522: Insufficiently Protected Credentials •
CVSS: 8.8EPSS: 0%CPEs: 3EXPL: 0CVE-2021-20182 – openshift: builder allows read and write of block devices
https://notcve.org/view.php?id=CVE-2021-20182
A privilege escalation flaw was found in openshift4/ose-docker-builder. The build container runs with high privileges using a chrooted environment instead of runc. If an attacker can gain access to this build container, they can potentially utilize the raw devices of the underlying node, such as the network and storage devices, to at least escalate their privileges to that of the cluster admin. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

https://notcve.org/view.php?id=CVE-2019-25014
A NULL pointer dereference was found in pkg/proxy/envoy/v2/debug.go getResourceVersion in Istio pilot before 1.5.0-alpha.0. If a particular HTTP GET request is made to the pilot API endpoint, it is possible to cause the Go runtime to panic (resulting in a denial of service to the istio-pilot application). Se encontró una desreferencia del puntero NULL en el archivo pkg/proxy/envoy/v2/debug.go en la función getResourceVersion en Istio pilot versiones anteriores a 1.5.0-alpha.0. Si es realizado una petición HTTP GET en particular al endpoint de la API pilot, es posible que el tiempo de ejecución de Go entre en pánico (resultando en una denegación de servicio para la aplicación istio-pilot) An out-of-bounds read flaw was found in istio-pilot. This flaw allows an attacker to send a crafted HTTP GET request to the pilot debug API endpoint. • https://bugzilla.redhat.com/show_bug.cgi?id=1919066 https://github.com/istio/istio/compare/1.4.2...1.5.0-alpha.0 https://access.redhat.com/security/cve/CVE-2019-25014 • CWE-125: Out-of-bounds Read CWE-476: NULL Pointer Dereference •

A flaw was found in multiple versions of OpenvSwitch. Specially crafted LLDP packets can cause memory to be lost when allocating data to handle specific optional TLVs, potentially causing a denial of service. The highest threat from this vulnerability is to system availability.
