NVD Description

Note: Versions mentioned in the description apply only to the upstream python3-debuginfo package and not the python3-debuginfo package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2 relevant fixed versions and status.

DISPUTED: The project has clarified that the documentation was incorrect, and that pkgutil.get_data() has the same security model as open(). The documentation has been updated to clarify this point. There is no vulnerability in the function if following the intended security model.

pkgutil.get_data() did not validate the resource argument as documented, allowing path traversals.
