Description Vincent Danen 2013-11-05 18:17:46 EST
It was reported [1] that IBUS 1.5.4 (and possibly 1.5.2) do not properly obscure password entry if a special "intent" is not provided.

A fix in ibus-anthy [2] illustrates what is necessary to provide the input purpose for the gnome-shell password dialog.  A similar patch exists for ibus-mozc [3].

The SUSE bug report notes the following engines are affected:

* ibus-mozc
* ibus-anthy (upstream 1.5.4 is fixed; in current Fedora)
* ibus-pinyin
* ibus-chewing

The vulnerability is in these engines due to the changes in IBUS, so it only affects these engines when IBUS >= 1.5.4 (or 1.5.2, it hasn't been determine precisely from what I can see) and GNOME 3.6+ are used together.

[bug 1013398] is for ibus-kkc that I reported 1 month ago.

FYI, in [bug 1013299], I discussed further privacy impact of this issue when an arbitrary person can use an IME that is running under certain user's profile.
Comment 5 Yohei Yukawa 2013-11-06 07:16:12 EST
[bug 1013789] is for ibus-mozc, which has already been fixed.
