sudo-rs: Partial password reveal is possible after timeout

### Summary If a user begins entering a password but does not press return for an extended period, a password timeout may occur. When this happens, the keystrokes that were entered are echoed back to the console. ### Example Using sudo-rs: ``` geiger@cerberus:~$ sudo -s [sudo: authenticate] Password: sudo-rs: timed out geiger@cerberus:~$ testtesttest ``` "testtesttest" was entered at the password prompt but not confirmed by pressing return and then waiting for the timeout. ### Impact This could reveal partial password information, possibly exposing history files when not carefully handled by the user and on screen, usable for Social Engineering or Pass-By attacks. ### Versions affected Passwords timeouts were added in sudo-rs 0.2.7 (with a default set to 5 minutes). ### Credits This issue was discovered and reported by @DevLaTron.
