FreeBSD : tor -- traffic confirmation attack (31c09848-1829-11e4-bf04-60a44c524f57)

Medium Nessus Plugin ID 76922


The remote FreeBSD host is missing one or more security-related updates.


The Tor Project reports :

Tor before and 0.2.5 before maintains a circuit after an inbound RELAY_EARLY cell is received by a client, which 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.


Update the affected packages.
