Summary
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.

Summary
Red Hat Security Advisory: qemu-kvm-rhev security update
Notes
Topic
Updated qemu-kvm-rhev packages that fix two security issues are now
available for Red Hat Enterprise Linux OpenStack Platform 6.
Red Hat Product Security has rated this update as having Important security
impact. Common Vulnerability Scoring System (CVSS) base scores, which give
detailed severity ratings, are available for each vulnerability from the
CVE links in the References section.
Details
KVM (Kernel-based Virtual Machine) 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 (NCQ) 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. (CVE-2016-1568)
An out-of-bounds read/write flaw was discovered in the way QEMU's Firmware
Configuration device emulation processed certain firmware configurations.
A privileged (CAP_SYS_RAWIO) 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. (CVE-2016-1714)
Red Hat would like to thank Qinghao Tang of Qihoo 360 Marvel Team for
reporting the CVE-2016-1568 issue, and Donghai Zhu of Alibaba for reporting
the CVE-2016-1714 issue.
All qemu-kvm-rhev 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.

Summary
Red Hat Security Advisory: qemu-kvm-rhev security update
Notes
Topic
Updated qemu-kvm-rhev packages that fix two security issues are now
available for Red Hat Enterprise Linux OpenStack Platform 5.0 for Red Hat
Enterprise Linux 7.
Red Hat Product Security has rated this update as having Important security
impact. Common Vulnerability Scoring System (CVSS) base scores, which give
detailed severity ratings, are available for each vulnerability from the
CVE links in the References section.
Details
KVM (Kernel-based Virtual Machine) 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 (NCQ) 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. (CVE-2016-1568)
An out-of-bounds read/write flaw was discovered in the way QEMU's Firmware
Configuration device emulation processed certain firmware configurations.
A privileged (CAP_SYS_RAWIO) 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. (CVE-2016-1714)
Red Hat would like to thank Qinghao Tang of Qihoo 360 Marvel Team for
reporting the CVE-2016-1568 issue, and Donghai Zhu of Alibaba for reporting
the CVE-2016-1714 issue.
All qemu-kvm-rhev 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.

Summary
Red Hat Security Advisory: qemu-kvm-rhev security update
Notes
Topic
Updated qemu-kvm-rhev packages that fix two security issues are now
available for Red Hat Enterprise Linux OpenStack Platform 7.
Red Hat Product Security has rated this update as having Important security
impact. Common Vulnerability Scoring System (CVSS) base scores, which give
detailed severity ratings, are available for each vulnerability from the
CVE links in the References section.
Details
KVM (Kernel-based Virtual Machine) 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 (NCQ) 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. (CVE-2016-1568)
An out-of-bounds read/write flaw was discovered in the way QEMU's Firmware
Configuration device emulation processed certain firmware configurations.
A privileged (CAP_SYS_RAWIO) 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. (CVE-2016-1714)
Red Hat would like to thank Qinghao Tang of Qihoo 360 Marvel Team for
reporting the CVE-2016-1568 issue, and Donghai Zhu of Alibaba for reporting
the CVE-2016-1714 issue.
All qemu-kvm-rhev 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.

Summary
Red Hat Security Advisory: qemu-kvm-rhev security and bug fix update
Notes
Topic
Updated qemu-kvm-rhev packages that fix two security issues and three bugs
are now available for Red Hat Enterprise Virtualization.
Red Hat Product Security has rated this update as having Important security
impact. Common Vulnerability Scoring System (CVSS) base scores, which give
detailed severity ratings, are available for each vulnerability from the
CVE links in the References section.
Details
KVM (Kernel-based Virtual Machine) 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 (NCQ) 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. (CVE-2016-1568)
An out-of-bounds read/write flaw was discovered in the way QEMU's Firmware
Configuration device emulation processed certain firmware configurations.
A privileged (CAP_SYS_RAWIO) 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. (CVE-2016-1714)
Red Hat would like to thank Qinghao Tang of Qihoo 360 Marvel Team for
reporting the CVE-2016-1568 issue, and Donghai Zhu of Alibaba for reporting
the CVE-2016-1714 issue.
This update also fixes the following bugs:
* Incorrect handling of the last sector of an image file could trigger an
assertion failure in qemu-img. This update changes the handling of the last
sector, and no assertion failure occurs. (BZ#1299345)
* Previously, rebooting a guest after multiple memory hot-plugs in some
cases caused the qemu-kvm process to terminate unexpectedly, and the reboot
to fail. This update fixes the problem, and guests with hot-plugged memory
reboot successfully. (BZ#1288096)
* When the OHCI driver received an interrupt during the suspending process,
the interrupt was not acknowledged. As a consequence, the interrupt kept
being sent repeatedly, and the system became unresponsive. This update
modifies the suspend procedure to acknowledge the interrupt, which prevents
the described problem. (BZ#1298971)
All qemu-kvm-rhev 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.
