Produktbeschreibung: Xen ist ein Virtueller-Maschinen-Monitor (VMM), der Hardware (x86, IA-64, PowerPC) für die darauf laufenden Systeme (Domains) paravirtualisiert.
Angriff: Ein lokaler Angreifer kann mehrere Schwachstellen in Xen ausnutzen, um einen Denial of Service Angriff durchzuführen.
Betroffene Betriebssysteme: - Linux
- UNIX
- Windows
Es bestehen mehrere Schwachstellen in Xen. Diese Fehler bestehen in den HVM-Hyperaufrufen und während der BTC/SRSO-Abschwächungen aufgrund einer unsachgemäßen Fehlerprüfung und eines logischen Fehlers. Ein lokaler Angreifer kann diese Schwachstellen ausnutzen, um einen Denial-of-Service-Zustand zu verursachen.
