Install libpam-tmpdir by entering the following commands in the terminal:
sudo apt update sudo apt install libpam-tmpdir
Description:
automatic per-user temporary directories
Many programs use $TMPDIR for storing temporary files. Not all of them are good at securing the permissions of those files. libpam-tmpdir sets $TMPDIR and $TMP for PAM sessions and sets the permissions quite tight. This helps system security by having an extra layer of security, making such symlink attacks and other /tmp based attacks harder or impossible
