Descriptions

An improper file permissions vulnerability affects Kata Containers prior to 1.11.5. When using a Kubernetes hostPath volume and mounting either a file or directory into a container as readonly, the file/directory is mounted as readOnly inside the container, but is still writable inside the guest. For a container breakout situation, a malicious guest can potentially modify or delete files/directories expected to be read-only.

Una vulnerabilidad de permisos de archivo inapropiados afecta a Kata Containers versiones anteriores a 1.11.5. Cuando se usa un volumen hostPath de Kubernetes y se monta un archivo o directorio en un contenedor como de solo lectura, el file/directory es montado como readOnly dentro del contenedor, pero aún puede ser escribible dentro del invitado. Para una situación de fuga de contenedor, un invitado malicioso puede modificar o eliminar files/directories que se espera sean de solo lectura
