CVE-2016-5126, CVE-2016-5403
12th August, 2016
A security issue affects these releases of Ubuntu and its
derivatives:
USN-3047-1 introduced a regression in QEMU.
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 Ubuntu 16.04 LTS.
(CVE-2016-4439, CVE-2016-4441, CVE-2016-5238, CVE-2016-5338, CVE-2016-6351)
Li Qiang and Qinghao Tang discovered that QEMU incorrectly handled the
VMWare VGA module. A privileged attacker inside the guest could use this
issue to cause QEMU to crash, resulting in a denial of service, or possibly
to obtain sensitive host memory. (CVE-2016-4453, CVE-2016-4454)
Li Qiang discovered that QEMU incorrectly handled VMWARE PVSCSI paravirtual
SCSI bus emulation support. A privileged attacker inside the guest could
use this issue to cause QEMU to crash, resulting in a denial of service.
This issue only applied to Ubuntu 14.04 LTS and Ubuntu 16.04 LTS.
(CVE-2016-4952)
Li Qiang discovered that QEMU incorrectly handled MegaRAID SAS 8708EM2 Host
Bus Adapter emulation support. A privileged attacker inside the guest could
use this issue to cause QEMU to crash, resulting in a denial of service, or
possibly to obtain sensitive host memory. This issue only applied to Ubuntu
14.04 LTS and Ubuntu 16.04 LTS. (CVE-2016-5105, CVE-2016-5106,
CVE-2016-5107, CVE-2016-5337)
It was discovered that QEMU incorrectly handled certain iSCSI asynchronous
I/O ioctl calls. An 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 Ubuntu 16.04 LTS.
(CVE-2016-5126)
Zhenhao Hong discovered that QEMU incorrectly handled the Virtio module. A
privileged attacker inside the guest could use this issue to cause QEMU to
crash, resulting in a denial of service. (CVE-2016-5403)
The problem can be corrected by updating your system to the following
package version:
To update your system, please follow these instructions:
