CVE-2013-4509
First published: Tue Nov 05 2013(Updated: )
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.
