Produktbeschreibung: Xen ist ein Virtueller-Maschinen-Monitor (VMM), der Hardware (x86, IA-64, PowerPC) für die darauf laufenden Systeme (Domains) paravirtualisiert.
Citrix XenServer ist eine Lösung für das Management, die Konfiguration und den Betrieb virtueller Maschinen auf Servern.
Citrix Hypervisor ist eine Plattform für Desktop-, Server- und Cloud-Virtualisierungsinfrastrukturen.
Angriff: Ein entfernter, authentisierter Angreifer kann eine Schwachstelle in XEN, Citrix XenServer und Citrix Systems Hypervisor ausnutzen, um einen Denial of Service Angriff durchzuführen.
Betroffene Betriebssysteme: - Sonstiges
- Windows
Es besteht eine Schwachstelle in XEN, Citrix Systems XenServer und Citrix Systems Hypervisor. Dieser Fehler existiert in der Funktion vlapic_error der Komponente APIC Architecture Handler, die zu einem Deadlock führt. Ein böswilliger Administrator einer Gast-VM kann diese Schwachstelle ausnutzen, um einen Denial-of-Service-Zustand auf dem Host zu erzeugen.
