Synopsis :

updates.

Description :

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. (CVE-2015-1779)

After installing this update, shut down all running virtual machines.
Once all virtual machines have shut down, start them again for this
update to take effect.
