Descriptions

containerd is a container runtime available as a daemon for Linux and Windows. A bug was found in containerd prior to versions 1.6.1, 1.5.10, and 1.14.12 where containers launched through containerd’s CRI implementation on Linux with a specially-crafted image configuration could gain access to read-only copies of arbitrary files and directories on the host. This may bypass any policy-based enforcement on container setup (including a Kubernetes Pod Security Policy) and expose potentially sensitive information. Kubernetes and crictl can both be configured to use containerd’s CRI implementation. This bug has been fixed in containerd 1.6.1, 1.5.10, and 1.4.12. Users should update to these versions to resolve the issue.

containerd es un tiempo de ejecución de contenedores disponible como demonio para Linux y Windows. Se ha encontrado un fallo en containerd versiones anteriores a 1.6.1, 1.5.10 y 1.14.12, en el que los contenedores lanzados mediante la implementación CRI de containerd en Linux con una configuración de imagen especialmente diseñada podían conseguir acceso a copias de sólo lectura de archivos y directorios arbitrarios en el host. Esto puede omitir cualquier aplicación basada en políticas sobre la configuración de contenedores (incluyendo una política de seguridad de Kubernetes Pod) y exponer información potencialmente confidencial. Kubernetes y crictl pueden ser configurados para usar la implementación de CRI de containerd. Este error ha sido corregido en containerd versiones 1.6.1, 1.5.10 y 1.4.12. Los usuarios deben actualizar a estas versiones para resolver el problema

containerd suffers from an insecure handling vulnerability related to image volumes.
