A flaw was found in the way QEMU emulated the e1000 network interface card when the host was configured to accept jumbo network frames, and a fully- virtualized guest using the e1000 emulated driver was not. A remote attacker could use this flaw to crash the guest or, potentially, execute arbitrary code with root privileges in the guest.
(CVE-2012-6075)

After installing the updated packages, all running fully-virtualized guests must be restarted for this update to take effect.
