Comment 1 Niels de Vos 2012-03-16 10:40:46 UTC
english-typing-booster should probably check the flags of the tty.

For example:

1) write something on the terminal
$ echo hello world

2) disable echo'ing
$ stty -echo

3) write something again
$ echo hello world

4) enable echo'ing
$ stty echo

5) write something again
$ echo hello world

My terminal shows (including input):
[ndevos@ndevos-laptop ~]$ echo hello world
hello world
[ndevos@ndevos-laptop ~]$ stty -echo
[ndevos@ndevos-laptop ~]$ hello world
[ndevos@ndevos-laptop ~]$ [ndevos@ndevos-laptop ~]$ echo hello world
hello world
[ndevos@ndevos-laptop ~]$ 

I am not sure if gnome-terminal offers a way to check the flags in a terminal, but you will probably want to have this functionality for any terminal emulator.

Same in Fedora 19. I just created a new user, and this 'feature' is on by default. It shows the passwords in cleartext while typing not only in termnal windows, but also in the gnome screen lock, the pop-up that asks for admin password, etc. A major security problem. I think severity should at least 'high' for this one!

Comment 3 Fedora End Of Life 2013-07-03 19:43:10 UTC
This message is a reminder that Fedora 17 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 17. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '17'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 17's end of life.

Bug Reporter:  Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 17 is end of life. If you 
would still like  to see this bug fixed and are able to reproduce it 
against a later version  of Fedora, you are encouraged  change the 
'version' to a later Fedora version prior to Fedora 17's end of life.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Comment 4 Mike FABIAN 2013-07-11 07:01:52 UTC
That is not really specific to ibus-typing-booster.

The preëdit of *any* input method is visible when typing passwords
in terminals after something like “su -”.

Comment 6 Jan Kurik 2015-07-15 15:10:50 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 23 development cycle.
Changing version to '23'.

(As we did not run this process for some time, it could affect also pre-Fedora 23 development
cycle bugs. We are very sorry. It will help us with cleanup during Fedora 23 End Of Life. Thank you.)

*All* input have this problem in terminals, not only ibus-typing-booster.
That is because there is no way for an input method to find out whether
the terminal is excpecting a password. The terminal does
not set any hints the input method could use and the input method
has no way to get the text which is currently displayed in the terminal
because terminals don’t support surrounding text. 

I.e. there is no way to fix this in an ibus-input-method.
