Package: openvpn
Version: 2.4.7-1
Severity: normal
It seems that openvpn does not handle SIGINT correctly when in client mode
with option auth-user-pass enabled. If I press ^C when presented with prompt
"Enter Auth Username: ", the terminal settings are not reset to a usable state.
Steps to reproduce:
1. Have a working config.ovpn with option auth-user-pass set
2. # openvpn config.ovpn
3. Press ^C
4. Press Enter (for empty password) and let the authentication fail
Openvpn client terminates and the client does not echo input.
Output of stty from that terminal:
speed 38400 baud; line = 0;
min = 1; time = 0;
-brkint -imaxbel iutf8
-icanon -echo
Output of stty from a new working terminal:
speed 38400 baud; line = 0;
-brkint -imaxbel iutf8
