Produktbeschreibung: Libvirt ist eine Bibliothek, die Schnittstellen zu den Virtualisierungsfunktionen von Linux anbietet und Werkzeuge zur Verwaltung von virtualisierten Systemen zur Verfügung stellt.
Angriff: Ein lokaler Angreifer kann eine Schwachstelle in libvirt ausnutzen, um einen Denial of Service Zustand herbeizuführen oder um seine Privilegien zu erhöhen.
Betroffene Betriebssysteme: - Linux
In libvirt besteht eine Schwachstelle aufgrund eines Double Free Speicherproblems in der libvirt-API. Ein lokaler Angreifer, der eine Verbindung mit dem "read-write socket" mit eingeschränkten ACL-Berechtigungen herstellt, kann dies ausnutzen, um einen Denial of Service Zustand des libvirt-Daemons zu herbeizuführen, sowie potenziell seine Privilegien zu erweitern.
