D-Bus before 1.15.6 sometimes allows unprivileged users to crash dbus-daemon. If a privileged user with control over the dbus-daemon is using the org.freedesktop.DBus.Monitoring interface to monitor message bus traffic, then an unprivileged user with the ability to connect to the same dbus-daemon can cause a dbus-daemon crash under some circumstances via an unreplyable message. When done on the well-known system bus, this is a denial-of-service vulnerability. The fixed versions are 1.12.28, 1.14.8, and 1.15.6.
D-Bus en versiones anteriores a v1.15.6 a veces permite a usuarios sin privilegios bloquear el "dbus-daemon". Si un usuario privilegiado con control sobre "dbus-daemon" está usando la interfaz "org.freedesktop.DBus.Monitoring" para monitorizar el tráfico del bus de mensajes, entonces un usuario sin privilegios con la capacidad de conectarse al mismo "dbus-daemon" puede causar un fallo del "dbus-daemon" bajo algunas circunstancias a través de un mensaje sin respuesta. Cuando se hace en el bus del sistema conocido, se trata de una vulnerabilidad de denegación de servicio. Las versiones que corrigen esta vulnerabilidad son v1.12.28, v1.14.8 y v1.15.6.
