CVE-2016-1568

Status Candidate

Overview

Use-after-free vulnerability in hw/ide/ahci.c in QEMU, when built with IDE AHCI Emulation support, allows guest OS users to cause a denial of service (instance crash) or possibly execute arbitrary code via an invalid AHCI Native Command Queuing (NCQ) AIO command.

Ubuntu Security Notice USN-2891-1
Posted Feb 3, 2016
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 2891-1 - Qinghao Tang discovered that QEMU incorrectly handled PCI MSI-X support. 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 14.04 LTS and Ubuntu 15.10. Lian Yihan discovered that QEMU incorrectly handled the VNC server. A remote attacker could use this issue to cause QEMU to crash, resulting in a denial of service. Various other issues were also addressed.

Red Hat Security Advisory 2016-0087-01 - KVM is a full virtualization solution for Linux on AMD64 and Intel 64 systems. The qemu-kvm-rhev package provides the user-space component for running virtual machines using KVM. A use-after-free flaw was found in the way QEMU's IDE AHCI emulator processed certain AHCI Native Command Queuing AIO commands. A privileged guest user could use this flaw to crash the QEMU process instance or, potentially, execute arbitrary code on the host with privileges of the QEMU process. An out-of-bounds read/write flaw was discovered in the way QEMU's Firmware Configuration device emulation processed certain firmware configurations. A privileged guest user could use this flaw to crash the QEMU process instance or, potentially, execute arbitrary code on the host with privileges of the QEMU process.
