Descriptions
The VNC websocket frame decoder in QEMU allows remote attackers to cause a denial of service (memory and CPU consumption) via a large (1) websocket payload or (2) HTTP headers section.
El decodificador de frames websocket VNC en QEMU permite a atacantes remotos causar una denegación de servicio (consumo de CPU y memoria) a través de una gran (1) carga útil websocket o (2) sección de cabeceras HTTP
It was found that the QEMU's websocket frame decoder processed incoming frames without limiting resources used to process the header and the payload. An attacker able to access a guest's VNC console could use this flaw to trigger a denial of service on the host by exhausting all available memory and CPU.
