Description

Michael S. Tsirkin discovered that QEMU incorrectly handled vmxnet3 devices. A local guest could possibly use this issue to cause a denial of service, or possibly execute arbitrary code on the host. This issue only applied to Ubuntu 13.10 and Ubuntu 14.04 LTS. (CVE-2013-4544)

Michael S. Tsirkin discovered that QEMU incorrectly handled virtio-net MAC addresses. A local guest could possibly use this issue to cause a denial of service, or possibly execute arbitrary code on the host. (CVE-2014-0150)

Benoit Canet discovered that QEMU incorrectly handled SMART self-tests. A local guest could possibly use this issue to cause a denial of service, or possibly execute arbitrary code on the host. (CVE-2014-2894).

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.
