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.
Affected products
- Debian Linux: 10.0
- Fedoraproject Fedora: 39, 40
- GNOME GLib: before 2.78.5; from 2.79.0 before 2.80.1 — fixed in 2.78.5, 2.80.1
- NetApp Ontap Tools: 10
How to fix
Upgrade to a fixed version: GNOME GLib 2.78.5, 2.80.1. Check the vendor advisory for mitigations.
