[Virtual-pkg-base-maintainers] Bug#683177: base: strange behaviour in getty/login on the ttys. user is able to move the cursor all over the screen.

Package: base
Severity: important

Dear Maintainer,

The getty login screens on wheezy allow the user to move the cursor at the 
beginning of the "login:" prompt line, thus overwriting the "login:" string.
It is also possible to move the cursor down and while at the bottom pressing 
the "Enter" key will allow the screen to scroll down further.
After that the only way to bring the prompt back is to press Ctrl+C.

The normal behaviour should be the tty showing a ^[[D each time the user press 
an arrow key. This correct behaviour happens only after a failed login, but 
after 
some minutes the tty get back to the "weird-mode".

It is not possible to login if the cursor has been moved down the screen. (but 
you can login if the cursor has been moved at the beginning of the "login:" 
line).

I think this problem only affects wheezy, because on irc some other users 
confirmed that squeeze has not this kind of problem.
I think the problem has something to do with the getty program (instead of the 
login program) because "ps auxf" shows that while 'weird-mode' is on the only 
program on the tty is getty.

It happens on all the six ttys and sometime i find some (never used) tty like 
tty4 with part of the "login:" string deleted and the cursor is some characters 
before 
the prompt.
