Описание
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:
"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).

sudo-rs is a memory safe implementation of sudo and su written in Rust. Starting in version 0.2.7 and prior to version 0.2.10, 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. 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. Version 0.2.10 fixes the issue.
