Descriptions

A malicious guest compromised before a container creation (e.g. a malicious guest image or a guest running multiple containers) can trick the kata runtime into mounting the untrusted container filesystem on any host path, potentially allowing for code execution on the host. This issue affects: Kata Containers 1.11 versions earlier than 1.11.1; Kata Containers 1.10 versions earlier than 1.10.5; Kata Containers 1.9 and earlier versions.

Un invitado malicioso comprometido antes de la creación de un contenedor (por ejemplo, una imagen maliciosa del invitado o un invitado que ejecuta múltiples contenedores) puede engañar al tiempo de ejecución de kata para que monte el sistema de archivos del contenedor no confiable en cualquier ruta de host, permitiendo potencialmente una ejecución de código en el host. Este problema afecta a: Kata Containers versiones 1.11 anteriores a 1.11.1; Kata Containers versiones 1.10 anteriores a 1.10.5; Kata Containers versiones 1.9 y anteriores
