How to fix?

Upgrade Ubuntu:14.04 qemu to version 2.0.0+dfsg-2ubuntu1.9 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.

The host_from_stream_offset function in arch_init.c in QEMU, when loading RAM during migration, allows remote attackers to execute arbitrary code via a crafted (1) offset or (2) length value in savevm data.
