Описание
Qemu, when built with VNC display driver support, allows remote attackers to cause a denial of service (arithmetic exception and application crash) via crafted SetPixelFormat messages from a client.
An arithmetic-exception flaw was found in the QEMU emulator built with VNC display-driver support. The VNC server incorrectly handled 'SetPixelFormat' messages sent from clients. A privileged remote client could use this flaw to crash the guest resulting in denial of service.
