Title: USN-2409-1 -- QEMU vulnerabilities
Description: Laszlo Ersek discovered that QEMU incorrectly handled memory in the vga device. A malicious guest could possibly use this issue to read arbitrary host memory. This issue only affected Ubuntu 14.04 LTS and Ubuntu 14.10. (<a href="http://people.ubuntu.com/~ubuntu-security/cve/CVE-2014-3615">CVE-2014-3615</a>) Xavier Mehrenberger and Stephane Duverger discovered that QEMU incorrectly handled certain udp packets when using guest networking. A malicious guest could possibly use this issue to cause a denial of service. (<a href="http://people.ubuntu.com/~ubuntu-security/cve/CVE-2014-3640">CVE-2014-3640</a>) It was discovered that QEMU incorrectly handled parameter validation in the vmware_vga device. A malicious guest could possibly use this issue to write into memory of the host, leading to privilege escalation. (<a href="http://people.ubuntu.com/~ubuntu-security/cve/CVE-2014-3689">CVE-2014-3689</a>) It was discovered that QEMU incorrectly handled USB xHCI controller live migration. An attacker could possibly use this issue to cause a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 14.04 LTS. (<a href="http://people.ubuntu.com/~ubuntu-security/cve/CVE-2014-5263">CVE-2014-5263</a>) Michael S. Tsirkin discovered that QEMU incorrectly handled memory in the ACPI PCI hotplug interface. A malicious guest could possibly use this issue to access memory of the host, leading to information disclosure or privilege escalation. This issue only affected Ubuntu 14.04 LTS. (<a href="http://people.ubuntu.com/~ubuntu-security/cve/CVE-2014-5388">CVE-2014-5388</a>) James Spadaro discovered that QEMU incorrectly handled certain VNC bytes_per_pixel values. An attacker having access to a VNC console could possibly use this issue to cause a guest to crash, resulting in a denial of service.
