Description
A security issue has been found in Tor <= 0.3.0.8, which could make it easier to eavesdrop on Tor users' traffic. When choosing which guard to use for a circuit, Tor avoids using a node that is in the same family that the exit node it selected, but this check was accidentally removed in 0.3.0.
