Upgrade tuf to version 0.12 or higher.
Overview
tuf is a secure updater framework for Python.
Affected versions of this package are vulnerable to Improper Authorization. It will incorrectly trust a previously downloaded root metadata file which failed verification at download time. This allows an attacker who is able to serve multiple new versions of root metadata (i.e. by a person-in-the-middle attack) culminating in a version which has not been correctly signed to control the trust chain for future updates.
