If you cannot patch yet, limit untrusted user access on shared systems where GDBus clients subscribe to trusted system service signals. Monitor vendor channels for official fixes or updates addressing this issue.
Description
An issue was discovered in GNOME GLib before 2.78.5, and 2.79.x and 2.80.x before 2.80.1. When a GDBus-based client subscribes to signals from a trusted system service such as NetworkManager on a shared computer, other users of the same computer can send spoofed D-Bus signals that the GDBus-based client will wrongly interpret as having been sent by the trusted system service. This could lead to the GDBus-based client behaving incorrectly, with an application-dependent impact.
