CVE-2019-14822

Intelligent Input Bus for Linux OS

Security Fix(es):

A flaw was discovered in ibus that allows any unprivileged user to monitor and send method calls to the ibus bus of another user due to a misconfiguration in the DBus server setup. A local attacker may use this flaw to intercept all keystrokes of a victim user who is using the graphical interface, change the input method engine, or modify other input related configurations of the victim user.(CVE-2019-14822)

A flaw was discovered in ibus in versions before 1.5.22 that allows any unprivileged user to monitor and send method calls to the ibus bus of another user due to a misconfiguration in the DBus server setup. A local attacker may use this flaw to intercept all keystrokes of a victim user who is using the graphical interface, change the input method engine, or modify other input related configurations of the victim user.

GLib provides the core application building blocks for libraries and applications written in C. It provides the core object system used in GNOME, the main loop implementation, and a large set of utility functions for strings and common data structures.

The Intelligent Input Bus (IBus) is an input method framework for multilingual input in Unix-like operating systems.

Security Fix(es):

• ibus: missing authorization allows local attacker to access the input bus of another user (CVE-2019-14822)

It was discovered that any unprivileged user could monitor and send method calls to the ibus bus of another user, due to a misconfiguration during the setup of the DBus server. When ibus is in use, a local attacker, who discovers the UNIX socket used by another user connected on a graphical environment, could use this flaw to intercept all keystrokes of the victim user or modify input related configurations through DBus method calls (CVE-2019-14822).

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.

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.
