Name of the Vulnerable Software and Affected Versions Tor versions 0.3.x before 0.3.0.9

Description The issue is related to the guard-selection algorithm, which only considers the exit relay and not its family. This might allow remote attackers to defeat intended anonymity properties by leveraging the existence of large families.
