Even after DSA-1709, /bin/login in Debian is vulnerable to a local DoS
attack; the attacker does not need special privileges to succeed. For
details please see

I do not know what practical uses this DoS could have.

(Debian and Ubuntu are vulnerable, I believe RedHat is not. I do not
know about other distros.)
