    Summary: ibus vulnerability

    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.
