      "value": "proot-distro is a utility for managing proot containers. Prior to version 5.1.5, proot-distro install extracted plain tarball root filesystems through _extract_plain_tar() in proot_distro/commands/install.py and Docker layers through _apply_layer() in proot_distro/helpers/docker.py without validating archive-controlled symlink targets in member.linkname, allowing a malicious archive to plant an absolute host-path symlink and write files through it onto the host filesystem. This issue is fixed in version 5.1.5."

Antes de la versión 5.1.5, proot-distro install extraía sistemas de archivos raíz de tarballs planos a través de _extract_plain_tar() en proot_distro/commands/install.py y capas de Docker a través de _apply_layer() en proot_distro/helpers/docker.py sin validar los destinos de enlaces simbólicos controlados por el archivo en member.linkname, permitiendo que un archivo malicioso plantara un enlace simbólico de ruta absoluta del host y escribiera archivos a través de él en el sistema de archivos del host. Este problema se solucionó en la versión 5.1.5."
