CVE-2017-16639
Tor Browser on Windows before 8.0 allows remote attackers to bypass the intended anonymity feature and discover a client IP address, a different vulnerability than CVE-2017-16541.
Does this matter?
Lower severity and a low EPSS score (2.35%). Track it; it rarely justifies an emergency change on its own.
