A flaw was found in the way the host’s qemu-kvm qxl driver and the guest’s X.Org qxl driver interacted when a SPICE connection terminated. A user able to initiate a SPICE connection to a guest could use this flaw to make the guest temporarily unavailable or, potentially (if the sysctl kernel.softlockup_panic variable was set to ‘1’ in the guest), crash the guest. (CVE-2013-0241)
All running X.Org server instances using the qxl driver must be restarted for this update to take effect.
