Ubuntu Security Notice USN-4134-3
March 24, 2020

ibus vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 19.10
- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS

Summary:

IBus could allow local users to capture key strokes of other locally logged
in users.

Software Description:
- ibus: Intelligent Input Bus - core

Details:

USN-4134-1 fixed a vulnerability in IBus. The update caused a regression in
some Qt applications and the fix was subsequently reverted in
USN-4134-2. The regression has since been resolved and so this update fixes
the original vulnerability.

We apologize for the inconvenience.

Original advisory details:

Simon McVittie discovered that IBus did not enforce appropriate access
controls on its private D-Bus socket. A local unprivileged user who
discovers the IBus socket address of another user could exploit this to
capture the key strokes of the other user.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 19.10:
ibus 1.5.21-1~exp2ubuntu2.1

Ubuntu 18.04 LTS:
ibus 1.5.17-3ubuntu5.3

Ubuntu 16.04 LTS:
ibus 1.5.11-1ubuntu2.4

After a standard system update you need to reboot your computer to make
all the necessary changes.
