CVE-2016-10028 [MEDIUM] QEMU vulnerabilities
Title: QEMU vulnerabilities
Summary: Several security issues were fixed in QEMU.
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. This issue only affected Ubuntu
16.04 LTS and Ubuntu 16.10. (CVE-2016-10028, CVE-2016-10029)
Li Qiang discovered that QEMU incorrectly handled the 6300esb watchdog. A
privileged attacker inside the guest could use this issue to cause QEMU to
crash, resulting in a denial of service. (CVE-2016-10155)
