Ubuntu 17.04 : qemu vulnerabilities (USN-3268-1)

High Nessus Plugin ID 99686

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

Zhenhao Hong discovered that QEMU incorrectly handled the Virtio GPU device. An attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service. (CVE-2016-10028)

It was discovered that QEMU incorrectly handled the JAZZ RC4030 device. A privileged attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service. (CVE-2016-8667)

Jann Horn discovered that QEMU incorrectly handled VirtFS directory sharing. A privileged attacker inside the guest could use this issue to access files on the host file system outside of the shared directory and possibly escalate their privileges. In the default installation, when QEMU is used with libvirt, attackers would be isolated by the libvirt AppArmor profile. (CVE-2016-9602)

Gerd Hoffmann discovered that QEMU incorrectly handled the Cirrus VGA device when being used with a VNC connection. 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.
(CVE-2016-9603)

Li Qiang discovered that QEMU incorrectly handled the Virtio GPU device. An attacker inside the guest could use this issue to cause QEMU to leak contents of host memory. (CVE-2016-9908)

Li Qiang discovered that QEMU incorrectly handled the Virtio GPU device. An attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service. (CVE-2016-9912, CVE-2017-5552, CVE-2017-5578)

Li Qiang discovered that QEMU incorrectly handled VirtFS directory sharing. A privileged attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service.
(CVE-2016-9914)

Jiang Xin and Wjjzhang discovered that QEMU incorrectly handled SDHCI device emulation. A privileged attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service.
(CVE-2017-5987)

Li Qiang discovered that QEMU incorrectly handled USB OHCI controller emulation. A privileged attacker inside the guest could use this issue to cause QEMU to hang, resulting in a denial of service.
(CVE-2017-6505).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
