How to fix?

Upgrade Ubuntu:14.04 qemu to version 2.0.0+dfsg-2ubuntu1.22 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.

QEMU (aka Quick Emulator) built with the NE2000 device emulation support is vulnerable to an OOB r/w access issue. It could occur while performing 'ioport' r/w operations. A privileged (CAP_SYS_RAWIO) user/process could use this flaw to leak or corrupt QEMU memory bytes.
