Produktbeschreibung: Libvirt ist eine Bibliothek, die Schnittstellen zu den Virtualisierungsfunktionen von Linux anbietet und stellt Werkzeuge zur Verfügung, um virtualisierte Systeme zu verwalten.
Angriff: Ein lokaler Angreifer kann eine Schwachstelle in libvirt ausnutzen, um seine Privilegien zu erhöhen.
Betroffene Betriebssysteme: - Linux
Es existiert eine Schwachstelle in libvirt. Der SocketMode-Parameter wird von den Gerätedateien virtlockd-admin.socket und virtlogd-admin.socket nicht ordnungsgemäß gesetzt. Dadurch entsteht ein offener UNIX-Domain-Socket. Ein unprivilegierter Benutzer kann diese Schwachstelle ausnutzen, um sich mit den Daemons virtlockd oder virtlogd verbinden, die administrativen RPC-Befehle verwenden und somit seine Rechte erhöhen.
