CVE-2016-1714

Status Candidate

Overview

The (1) fw_cfg_write and (2) fw_cfg_read functions in hw/nvram/fw_cfg.c in QEMU before 2.4, when built with the Firmware Configuration device emulation support, allow guest OS users with the CAP_SYS_RAWIO privilege to cause a denial of service (out-of-bounds read or write access and process crash) or possibly execute arbitrary code via an invalid current entry value in a firmware configuration.

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.
