sudo can be configured to run only from a pseudo-pty.
Note: visudo edits the sudoers file in a safe fashion, analogous to vipw(8). visudo locks the sudoers file against multiple simultaneous edits, provides basic sanity checks, and checks or parse errors. If the sudoers file is currently being edited you will receive a message to try again later.
Attackers can run a malicious program using sudo, which would again fork a background process that remains even when the main program has finished executing.
None.
Verify that sudo can only run other commands from a pseudo-pty. Run the following command:
grep -Ei '^\s*Defaults\s+([^#]+,\s*)?use_pty(,\s+\S+\s*)*(\s+#.*)?$' /etc/sudoers /etc/sudoers.d/*
The output should include a line matching:
Defaults use_pty
Edit the file /etc/sudoers or a file in /etc/sudoers.d/ with visudo -f and add the following line:
Defaults use_pty
By default, sudo does not require a pseudo-pty.
