Description Marcus Meissner 2015-03-24 14:08:23 UTC 
OSS:2015/Q1/989

It was found that the QEMU's websocket frame decoder processed incoming
frames without limiting resources used to process the header and
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.
