Descriptions

GuardDog is a CLI tool to identify malicious PyPI packages. Versions prior to 0.1.5 are vulnerable to Relative Path Traversal when scanning a specially-crafted local PyPI package. Running GuardDog against a specially-crafted package can allow an attacker to write an arbitrary file on the machine where GuardDog is executed due to a path traversal vulnerability when extracting the .tar.gz file of the package being scanned, which exists by design in the tarfile.TarFile.extractall function. This issue is patched in version 0.1.5.

GuardDog es una herramienta CLI para identificar paquetes PyPI maliciosos. Las versiones anteriores a la 0.1.5 son vulnerables a path traversal relativo cuando se escanea un paquete PyPI local especialmente manipulado. Ejecutar GuardDog contra un paquete especialmente manipulado puede permitir a un atacante escribir un archivo arbitrario en la máquina donde se ejecuta GuardDog debido a una vulnerabilidad de path traversal al extraer el archivo .tar.gz del paquete que se está analizando, que existe por diseño en el función tarfile.TarFile.extractall. Este problema está solucionado en la versión 0.1.5.
