"Updated qemu packages fix security vulnerabilities :

A denial of service flaw was found in the way QEMU handled malformed
Physical Region Descriptor Table (PRDT) data sent to the host's IDE
and/or AHCI controller emulation. A privileged guest user could use
this flaw to crash the system (rhbz#1204919).

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)."
