CVE-2024-34397: Debian Linux

Medium severity, CVSS 5.2. EPSS: 0.8% chance of exploitation in the next 30 days.

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 Debian Linux: version 10.0 only
• Fedoraproject Fedora: version 39 only; version 40 only
• Gnome Glib: before 2.78.5 (fixed in 2.78.5); from 2.79.0, before 2.80.1 (fixed in 2.80.1)
• Netapp Ontap Tools: version 10 only
