Descriptions

GuardDog is a CLI tool to identify malicious PyPI packages. Versions prior to v0.1.8 are vulnerable to arbitrary file write when scanning a specially-crafted remote PyPI package. Extracting files using shutil.unpack_archive() from a potentially malicious tarball without validating that the destination file path is within the intended destination directory can cause files outside the destination directory to be overwritten. This issue is patched in version 0.1.8. Potential workarounds include using a safer module, like zipfile, and validating the location of the extracted files and discarding those with malicious paths.

GuardDog es una herramienta CLI para identificar paquetes PyPI maliciosos. Las versiones anteriores a la v0.1.8 son vulnerables a la escritura arbitraria de archivos al escanear un paquete PyPI remoto especialmente manipulado. Extraer archivos utilizandoshutil.unpack_archive() de un tarball potencialmente malicioso sin validar que la ruta del archivo de destino esté dentro del directorio de destino deseado puede provocar que se sobrescriban los archivos fuera del directorio de destino. Este problema está solucionado en la versión 0.1.8. Los posibles workarounds incluyen el uso de un módulo más seguro, como zipfile, y validar la ubicación de los archivos extraídos y descartar aquellos con rutas maliciosas.
