Mageia 9 - MGASA-2024-0311 moderate: glib2.0 D-Bus signal issue

mageia
Calendar Grey September 25, 2024
Dist Mageia Esm H88
Revised glib2.0 versions from Mageia resolve a critical vulnerability related to D-Bus signal impersonation.
An issue was discovered in GNOME GLib before 2.78.5, and 2.79.x and 2.80.x before 2.80.1

Summary

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. (CVE-2024-34397)
