Furthermore, only the connection to the attacker will be affected, since a separate pppd process handles each ppp connection. In other words, an attacker can terminate their own connection, but they can not affect any other connection, or prevent new connections from being established. Given that, I don't think that this is even a DoS vulnerability. Paul.
