Releases

- ibus - Intelligent Input Bus - core
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 19.04
Ubuntu 18.04
Ubuntu 16.04
After a standard system update you need to reboot your computer to make
all the necessary changes.
