When clients receive a consensus - like this, they only use one of the relays. Without this fix, a - hostile relay could selectively disable some client use of target - relays by constucting a router descriptor with a different - identity and the same microdescriptor parameters and getting the - authorities to list it in a microdescriptor consensus. This fix - prevents an attacker from causing a microdescriptor collision, - because the router's identity is not forgeable. |
