USN-3047-1 fixed vulnerabilities in QEMU. The patch to fix CVE-2016-5403
caused a regression which resulted in save/restore failures when virtio
memory balloon statistics are enabled. This update temporarily reverts the
security fix for CVE-2016-5403 pending further investigation. We apologize
for the inconvenience.
Original advisory details:
Li Qiang discovered that QEMU incorrectly handled 53C9X Fast SCSI
controller emulation. A privileged attacker inside the guest could use this
issue to cause QEMU to crash, resulting in a denial of service, or possibly
execute arbitrary code on the host. In the default installation, when QEMU
is used with libvirt, attackers would be isolated by the libvirt AppArmor
profile. This issue only applied to Ubuntu 14.04 LTS and Ub
