Description Jonathan Kamens 2001-08-02 01:13:11 UTC
I accidentally typed my password in the username field of a gdm login
screen -- I thought the screen was locked rather than logged out, and I
typed the password before the monitor had a change to wake up.

Imagine my surprise when my password was logged in cleartext in
/var/log/messages!  "gdm[1384]: Couldn't authenticate XXXX"

It is a cardinal rule of designing login interfaces that you never log
information typed by the user, for just this reason.

Comment 1 Havoc Pennington 2001-08-02 15:31:09 UTC
Someone just reported this same bug for another reason, you can enter "%s%s%s"
as your password and get some uninitialized memory reads. Looks like it's "turn
off gdm logging crack" day.

gdm- should resolve this.
