Affected packages

• PyPI guarddog: < 0.1.5 → fixed in 0.1.5

Description

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.
