CVE-2013-4509

Published: 23 November 2013

The default configuration of IBUS 1.5.4, and possibly 1.5.2 and earlier, when IBus.InputPurpose.PASSWORD is not set and used with GNOME 3, does not obscure the entered password characters, which allows physically proximate attackers to obtain a user password by reading the lockscreen.

Notes

AuthorNote

1.5.4 only. Specifically "1.5.2 or lower do not handle the input
purpose so the typed chars are shown as the bug. 1.5.3 returns FALSE when the
input purpose is password in IBus GTK+ IM modules instead of sending the key
events to IBus engines so the problem does not appear. 1.5.4 adds the class
method of set_content_type() in IBusEngine and IBus GTK+ IM modules send the
input purpose to engines."
