The connection_edge_process_relay_cell function in or/relay.c in Tor before
0.2.3.25 maintains circuits even if an unexpected SENDME cell arrives,
which might allow remote attackers to cause a denial of service (memory
consumption or excessive cell reception rate) or bypass intended
flow-control restrictions via a RELAY_COMMAND_SENDME command.
