Descriptions

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.

Se descubrió un problema en GNOME GLib anterior a 2.78.5 y en 2.79.x y 2.80.x anterior a 2.80.1. Cuando un cliente basado en GDBus se suscribe a señales de un servicio de sistema confiable, como NetworkManager, en un ordenador compartido, otros usuarios del mismo ordenador pueden enviar señales D-Bus falsificadas que el cliente basado en GDBus interpretará erróneamente como enviadas por el mismo. servicio de sistema confiable. Esto podría provocar que el cliente basado en GDBus se comporte incorrectamente, con un impacto que depende de la aplicación.
