CVE-2017-0377 (opens in a new tab)Amendment
The Debian security team deemed this advisory irrelevant for Debian:11.
NVD Description
Note: Versions mentioned in the description apply only to the upstream tor package and not the tor package as distributed by Debian.
Tor 0.3.x before 0.3.0.9 has a guard-selection algorithm that only considers the exit relay (not the exit relay's family), which might allow remote attackers to defeat intended anonymity properties by leveraging the existence of large families.
