Detailed vulnerability description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to missing authorization for D-Bus signals. 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.
