medium Nessus Plugin ID 79244

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

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. (CVE-2014-3615)

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. (CVE-2014-3640)

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. (CVE-2014-3689)

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. (CVE-2014-5263)

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. (CVE-2014-5388)

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. (CVE-2014-7815).

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.
