Produktbeschreibung: QEMU ist eine freie Virtualisierungssoftware, die die gesamte Hardware eines Computers emuliert.
Angriff: Ein lokaler Angreifer kann mehrere Schwachstellen in QEMU ausnutzen, um einen Denial of Service Angriff durchzuführen.
Betroffene Betriebssysteme: - Linux
- UNIX
- Windows
In QEMU existieren mehrere Schwachstellen. Hier handelt es sich um einen Integer Überlauf im qemu-guest-agent und um eine Nullzeiger Dereferenzierung im QXL VGA card Emulator. Ein lokaler Angreifer kann diese Schwachstellen ausnutzen, um einen Denial of Service zu verursachen.
