Produktbeschreibung: QEMU ist eine freie Virtualisierungssoftware, die die gesamte Hardware eines Computers emuliert.
Angriff: Ein entfernter, authentisierter Angreifer kann eine Schwachstelle in QEMU ausnutzen, um einen Denial of Service Angriff durchzuführen.
Betroffene Betriebssysteme: - Linux - MacOS X - Sonstiges - UNIX - Windows
CVE-2019-20382

Es existiert eine Schwachstelle in QEMU, wenn "ZRLE Tight encoding" aktiviert ist. Der VNC-Anzeigetreiber behandelt Verbindungsunterbrechungen unsachgemäß. In der Folge kommt es zu einem Memory Leakage Problem. Ein entfernter, authentisierter Angreifer kann diese Schwachstelle ausnutzen, um einen Denial of Service zu verursachen.
