CVE-2020-8564 – Docker config secrets leaked when file is malformed and loglevel >= 4
https://notcve.org/view.php?id=CVE-2020-8564
In Kubernetes clusters using a logging level of at least 4, processing a malformed docker config file will result in the contents of the docker config file being leaked, which can include pull secrets or other registry credentials. This affects < v1.19.3, < v1.18.10, < v1.17.13. En los clústeres de Kubernetes que usan un nivel de registro de al menos 4, el procesamiento de un archivo de configuración de docker malformado dará como resultado la filtración del contenido del archivo de configuración de docker, que puede incluir secretos de extracción u otras credenciales de registro. Esto afecta versiones anteriores a v1.19.3, versiones anteriores a v1.18.10, versiones anteriores a v1.17.13 A flaw was found in kubernetes. In Kubernetes, if the logging level is to at least 4, processing a malformed docker config file will result in the contents of the docker config file being leaked, which can include pull secrets or other registry credentials. • https://github.com/kubernetes/kubernetes/issues/95622 https://groups.google.com/g/kubernetes-security-discuss/c/vm-HcrFUOCs/m/36utxAM5CwAJ https://security.netapp.com/advisory/ntap-20210122-0006 https://access.redhat.com/security/cve/CVE-2020-8564 https://bugzilla.redhat.com/show_bug.cgi?id=1886637 • CWE-117: Improper Output Neutralization for Logs CWE-532: Insertion of Sensitive Information into Log File •
CVE-2020-8557 – Kubernetes node disk Denial of Service by writing to container /etc/hosts
https://notcve.org/view.php?id=CVE-2020-8557
The Kubernetes kubelet component in versions 1.1-1.16.12, 1.17.0-1.17.8 and 1.18.0-1.18.5 do not account for disk usage by a pod which writes to its own /etc/hosts file. The /etc/hosts file mounted in a pod by kubelet is not included by the kubelet eviction manager when calculating ephemeral storage usage by a pod. If a pod writes a large amount of data to the /etc/hosts file, it could fill the storage space of the node and cause the node to fail. El componente kubelet de Kubenetes versiones 1.1-1.16.12, 1.17.0-1.17.8 y 1.18.0-1.18.5, no cuenta para el uso del disco por parte de un pod que escribe en su propio archivo /etc/hosts. El archivo /etc/hosts montado en un pod para kubelet no esta incluido para el administrador de desalojo de kubelet al calcular el uso de almacenamiento efímero por un pod. • https://github.com/kubernetes/kubernetes/issues/93032 https://groups.google.com/g/kubernetes-security-announce/c/cB_JUsYEKyY/m/vVSO61AhBwAJ https://security.netapp.com/advisory/ntap-20200821-0002 https://access.redhat.com/security/cve/CVE-2020-8557 https://bugzilla.redhat.com/show_bug.cgi?id=1835977 • CWE-400: Uncontrolled Resource Consumption •
