Michael S. Tsirkin discovered that QEMU incorrectly handled certain
parameters during ram load while performing a migration. An attacker able
to manipulate savevm data could use this issue to possibly execute
arbitrary code on the host. This issue only affected Ubuntu 12.04 LTS,
Ubuntu 14.04 LTS, and Ubuntu 14.10. (CVE-2014-7840)

Paolo Bonzini discovered that QEMU incorrectly handled memory in the Cirrus
VGA device. A malicious guest could possibly use this issue to write into
memory of the host, leading to privilege escalation. (CVE-2014-8106)
