    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
    IBus could allow local users to capture key strokes of other locally logged
    in users.
    Software Description:
    - ibus: Intelligent Input Bus - core
    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.
