[Full-disclosure] /bin/login DoS remains after DSA-1709

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   http://www.debian.org/security/2009/dsa-1709 http://bugs.debian.org/505271 http://bugs.debian.org/505071

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.)

Cheers,
