Descriptions

An issue was discovered in Podman in libpod before 1.6.0. It resolves a symlink in the host context during a copy operation from the container to the host, because an undesired glob operation occurs. An attacker could create a container image containing particular symlinks that, when copied by a victim user to the host filesystem, may overwrite existing files with others from the host.

Se descubrió un problema en Podman en libpod versiones anteriores a la versión 1.6.0. Resuelve un enlace simbólico (symlink) en el contexto del host durante una operación de copia desde el contenedor hacia el host, porque se produce una operación glob no deseada. Un atacante podría crear una imagen de contenedor que contenga enlaces simbólicos particulares que, cuando sean copiados por parte de un usuario víctima hacia el sistema de archivos del host, pueden sobrescribir los archivos existentes con otros del host.
