Es existiert eine Schwachstelle in Xen. Wenn ein Gerät aus einer Domäne entfernt wird, wird es nicht ordnungsgemäß unter Quarantäne gestellt und behält seinen Zugriff auf die Domäne, der es zuvor zugewiesen war. Ein Angreifer kann diese Schwachstelle ausnutzen, um Sicherheitsvorkehrungen zu umgehen.
