How to fix?

Upgrade Ubuntu:14.04 qemu to version 2.0.0+dfsg-2ubuntu1.7 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream qemu package and not the qemu package as distributed by Ubuntu. See How to fix? for Ubuntu:14.04 relevant fixed versions and status.

vmstate_xhci_event in hw/usb/hcd-xhci.c in QEMU 1.6.0 does not terminate the list with the VMSTATE_END_OF_LIST macro, which allows attackers to cause a denial of service (out-of-bounds access, infinite loop, and memory corruption) and possibly gain privileges via unspecified vectors.
