Name of the Vulnerable Software and Affected Versions Tor versions prior to 0.2.4.23 Tor versions 0.2.5 prior to 0.2.5.6-alpha

Description The issue makes it easier for remote attackers to conduct traffic-confirmation attacks by using the pattern of RELAY and RELAY EARLY cells as a means of communicating information about hidden service names. This occurs because Tor maintains a circuit after an inbound RELAY EARLY cell is received by a client.

Recommendations For Tor versions prior to 0.2.4.23, update to version 0.2.4.23 or later. For Tor versions 0.2.5 prior to 0.2.5.6-alpha, update to version 0.2.5.6-alpha or later.
