Detail

Synopsis

Multiple vulnerabilities have been found in QEMU, the worst of which allows context dependent attackers to cause Denial of Service.

Background

QEMU is a generic and open source machine emulator and virtualizer.

Description

Multiple vulnerabilities have been discovered in QEMU. Please review the CVE identifiers referenced below for details.

Impact

A context-dependent attacker could cause a Denial of Service condition and a local user can obtain sensitive information.

Workaround

There is no known workaround at this time.

Resolution

All QEMU users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-emulation/qemu-2.1.2-r1"

Title: RHSA-2014:1669 -- qemu-kvm security and bug fix update (Low)
Description: KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on AMD64 and Intel 64 systems. The qemu-kvm package provides the user-space component for running virtual machines using KVM. An information leak flaw was found in the way QEMU's VGA emulator accessed frame buffer memory for high resolution displays. A privileged guest user could use this flaw to leak memory contents of the host to the guest by setting the display to use a high resolution in the guest. (CVE-2014-3615) This issue was discovered by Laszlo Ersek of Red Hat. This update also fixes the following bug: * This update fixes a regression in the scsi_block_new_request() function, which caused all read requests to through SG_IO if the host cache was not used. (BZ#1141189) All qemu-kvm users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing this update, shut down all running virtual machines. Once all virtual machines have shut down, start them again for this update to take effect.

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.
