Software that reads /etc/passwd or /etc/shadow is quite sensitive, and should therefore be as simple as possible. More code, more bugs. The best mitigation for those attacks is to ban the names altogether. IMO, setuid programs should not accept Unicode. Have a lovely day! Alex -- <https://www.alejandro-colomar.es/>
