Summary
GuardDog vulnerable to arbitrary file write when scanning a specially-crafted PyPI package
Details

Impact

Running GuardDog against a specially-crafted package can allow an attacker to write an arbitrary file on the machine where GuardDog is executed.

This is 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. See also https://docs.python.org/3/library/tarfile.html#tarfile.TarFile.extractall

Remediation

Upgrade to GuardDog v0.1.5 or more recent.
