Summary
Red Hat Security Advisory: qemu-kvm-rhev security, bug fix, and enhancement update
Notes
Topic
An update for qemu-kvm-rhev is now available for Red Hat Enterprise Linux OpenStack Platform 7.0 (Kilo) for RHEL 7.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) 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 in environments managed by Red Hat Enterprise Virtualization Manager.
The following packages have been upgraded to a newer upstream version: qemu-kvm-rhev (2.6.0). (BZ#1386381)
Security Fix(es):
* An out-of-bounds flaw was found in the QEMU emulator built using 'address_space_translate' to map an address to a MemoryRegionSection. The flaw could occur while doing pci_dma_read/write calls, resulting in an out-of-bounds read-write access error. A privileged user inside a guest could use this flaw to crash the guest instance (denial of service). (CVE-2015-8817, CVE-2015-8818)
Red Hat would like to thank Donghai Zdh of Alibaba Inc. for reporting this issue.

Summary
Red Hat Security Advisory: qemu-kvm-rhev security, bug fix, and enhancement update
Notes
Topic
An update for qemu-kvm-rhev is now available for Red Hat OpenStack Platform 8.0 (Liberty).
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) 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 in environments managed by Red Hat Enterprise Virtualization Manager.
The following packages have been upgraded to a newer upstream version: qemu-kvm-rhev (2.6.0). (BZ#1386383)
Security Fix(es):
* An out-of-bounds flaw was found in the QEMU emulator built using 'address_space_translate' to map an address to a MemoryRegionSection. The flaw could occur while doing pci_dma_read/write calls, resulting in an out-of-bounds read-write access error. A privileged user inside a guest could use this flaw to crash the guest instance (denial of service). (CVE-2015-8817, CVE-2015-8818)
Red Hat would like to thank Donghai Zdh of Alibaba Inc. for reporting this issue.

Summary
Red Hat Security Advisory: qemu-kvm security and bug fix update
Notes
Topic
An update for qemu-kvm is now available for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security impact of Low. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
Kernel-based Virtual Machine (KVM) is a full virtualization solution for Linux on AMD64 and Intel 64 systems. The qemu-kvm packages provide the user-space component for running virtual machines using KVM.
Security Fix(es):
* An out-of-bounds read-access flaw was found in the QEMU emulator built with IP checksum routines. The flaw could occur when computing a TCP/UDP packet's checksum, because a QEMU function used the packet's payload length without checking against the data buffer's size. A user inside a guest could use this flaw to crash the QEMU process (denial of service). (CVE-2016-2857)
Red Hat would like to thank Ling Liu (Qihoo 360 Inc.) for reporting this issue.
Bug Fix(es):
* Previously, rebooting a guest virtual machine more than 128 times in a short period of time caused the guest to shut down instead of rebooting, because the virtqueue was not cleaned properly. This update ensures that the virtqueue is cleaned more reliably, which prevents the described problem from occurring. (BZ#1393484)

Summary
Red Hat Security Advisory: qemu-kvm-rhev security, bug fix, and enhancement update
Notes
Topic
An update for qemu-kvm-rhev is now available for Red Hat OpenStack Platform 9.0 (Mitaka).
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) 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 in environments managed by Red Hat Enterprise Virtualization Manager.
The following packages have been upgraded to a newer upstream version: qemu-kvm-rhev (2.6.0). (BZ#1386385)
Security Fix(es):
* An out-of-bounds flaw was found in the QEMU emulator built using 'address_space_translate' to map an address to a MemoryRegionSection. The flaw could occur while doing pci_dma_read/write calls, resulting in an out-of-bounds read-write access error. A privileged user inside a guest could use this flaw to crash the guest instance (denial of service). (CVE-2015-8817, CVE-2015-8818)
Red Hat would like to thank Donghai Zdh of Alibaba Inc. for reporting this issue.

Summary
Red Hat Security Advisory: qemu-kvm-rhev security, bug fix, and enhancement update
Notes
Topic
An update for qemu-kvm-rhev is now available for Red Hat Enterprise Linux OpenStack Platform 6.0 (Juno) for RHEL 7.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) 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 in environments managed by Red Hat Enterprise Virtualization Manager.
The following packages have been upgraded to a newer upstream version: qemu-kvm-rhev (2.6.0). (BZ#1386379)
Security Fix(es):
* An out-of-bounds flaw was found in the QEMU emulator built using 'address_space_translate' to map an address to a MemoryRegionSection. The flaw could occur while doing pci_dma_read/write calls, resulting in an out-of-bounds read-write access error. A privileged user inside a guest could use this flaw to crash the guest instance (denial of service). (CVE-2015-8817, CVE-2015-8818)
Red Hat would like to thank Donghai Zdh of Alibaba Inc. for reporting this issue.

Summary
Red Hat Security Advisory: qemu-kvm-rhev security and bug fix update
Notes
Topic
An update for qemu-kvm-rhev is now available for RHEV 3.X Hypervisor and Agents for RHEL-7 and RHEV 4.X RHEV-H and Agents for RHEL-7.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm-rhev packages provide the user-space component for running virtual machines that use KVM in environments managed by Red Hat products.
Security Fix(es):
* Quick emulator (QEMU) built with the Cirrus CLGD 54xx VGA emulator support is vulnerable to an out-of-bounds access issue. It could occur while copying VGA data via bitblt copy in backward mode. A privileged user inside a guest could use this flaw to crash the QEMU process resulting in DoS or potentially execute arbitrary code on the host with privileges of QEMU process on the host. (CVE-2017-2615)
* Quick emulator (QEMU) built with the Cirrus CLGD 54xx VGA Emulator support is vulnerable to an out-of-bounds access issue. The issue could occur while copying VGA data in cirrus_bitblt_cputovideo. A privileged user inside guest could use this flaw to crash the QEMU process OR potentially execute arbitrary code on host with privileges of the QEMU process. (CVE-2017-2620)
* An out-of-bounds read-access flaw was found in the QEMU emulator built with IP checksum routines. The flaw could occur when computing a TCP/UDP packet's checksum, because a QEMU function used the packet's payload length without checking against the data buffer's size. A user inside a guest could use this flaw to crash the QEMU process (denial of service). (CVE-2016-2857)
Red Hat would like to thank Wjjzhang (Tencent.com Inc.) and Li Qiang (360.cn Inc.) for reporting CVE-2017-2615 and Ling Liu (Qihoo 360 Inc.) for reporting CVE-2016-2857.
Bug Fix(es):
* Prior to this update, after migrating a guest virtual machine on the little-endian variant of IBM Power Systems and resetting the guest, the guest boot process failed with a "tcmalloc: large alloc" error message. This update fixes the bug, and the described problem no longer occurs. (BZ#1420456)
* The qemu-kvm-rhev package depends on the usbredir and libcacard packages. However, on the little-endian variant of IBM Power Systems, smartcard use is not supported and usbredir and libcacard are thus only available in the Optional channel. As a consequence, qemu-kvm-rhev was previously not installable on these systems if the Optional channel was not available for the user. This update removes usbredir and libcacard as dependencies of qemu-kvm-rhev on little-endian IBM Power Systems, and qemu-kvm-rhev can now be installed as expected in the described scenario. (BZ#1420428)

Summary
Red Hat Security Advisory: qemu-kvm-rhev security, bug fix, and enhancement update
Notes
Topic
An update for qemu-kvm-rhev is now available for Red Hat Enterprise Linux OpenStack Platform 5.0 (Icehouse) for RHEL 7.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) 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 in environments managed by Red Hat Enterprise Virtualization Manager.
The following packages have been upgraded to a newer upstream version: qemu-kvm-rhev (2.6.0). (BZ#1386377)
Security Fix(es):
* An out-of-bounds flaw was found in the QEMU emulator built using 'address_space_translate' to map an address to a MemoryRegionSection. The flaw could occur while doing pci_dma_read/write calls, resulting in an out-of-bounds read-write access error. A privileged user inside a guest could use this flaw to crash the guest instance (denial of service). (CVE-2015-8817, CVE-2015-8818)
Red Hat would like to thank Donghai Zdh of Alibaba Inc. for reporting this issue.

Summary
Red Hat Security Advisory: qemu-kvm-rhev security update
Notes
Topic
An update for qemu-kvm-rhev is now available for Red Hat Enterprise Linux OpenStack Platform 5.0 (Icehouse) for RHEL 6.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm-rhev packages provide the user-space component for running virtual machines that use KVM in environments managed by Red Hat products.
Security Fix(es):
* Quick emulator (QEMU) built with the Cirrus CLGD 54xx VGA emulator support is vulnerable to an out-of-bounds access issue. It could occur while copying VGA data via bitblt copy in backward mode. A privileged user inside a guest could use this flaw to crash the QEMU process resulting in DoS or potentially execute arbitrary code on the host with privileges of QEMU process on the host. (CVE-2017-2615)
* Quick emulator (QEMU) built with the Cirrus CLGD 54xx VGA Emulator support is vulnerable to an out-of-bounds access issue. The issue could occur while copying VGA data in cirrus_bitblt_cputovideo. A privileged user inside guest could use this flaw to crash the QEMU process OR potentially execute arbitrary code on host with privileges of the QEMU process. (CVE-2017-2620)
* An out-of-bounds read-access flaw was found in the QEMU emulator built with IP checksum routines. The flaw could occur when computing a TCP/UDP packet's checksum, because a QEMU function used the packet's payload length without checking against the data buffer's size. A user inside a guest could use this flaw to crash the QEMU process (denial of service). (CVE-2016-2857)

Summary
Red Hat Security Advisory: qemu-kvm security and bug fix update
Notes
Topic
An update for qemu-kvm is now available for Red Hat Enterprise Linux 6.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
Kernel-based Virtual Machine (KVM) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm packages provide the user-space component for running virtual machines that use KVM.
Security Fix(es):
* Quick emulator (Qemu) built with the Cirrus CLGD 54xx VGA emulator support is vulnerable to an out-of-bounds access issue. It could occur while copying VGA data via bitblt copy in backward mode. A privileged user inside a guest could use this flaw to crash the Qemu process resulting in DoS or potentially execute arbitrary code on the host with privileges of Qemu process on the host. (CVE-2017-2615)
* An out-of-bounds read-access flaw was found in the QEMU emulator built with IP checksum routines. The flaw could occur when computing a TCP/UDP packet's checksum, because a QEMU function used the packet's payload length without checking against the data buffer's size. A user inside a guest could use this flaw to crash the QEMU process (denial of service). (CVE-2016-2857)
Red Hat would like to thank Wjjzhang (Tencent.com Inc.) Li Qiang (360.cn Inc.) for reporting CVE-2017-2615 and Ling Liu (Qihoo 360 Inc.) for reporting CVE-2016-2857.
This update also fixes the following bug:
* Previously, rebooting a guest virtual machine more than 128 times in a short period of time caused the guest to shut down instead of rebooting, because the virtqueue was not cleaned properly. This update ensures that the virtqueue is cleaned more reliably, which prevents the described problem from occurring. (BZ#1408389)
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.

Summary
Red Hat Security Advisory: qemu-kvm-rhev security update
Notes
Topic
An update for qemu-kvm-rhev is now available for RHEV 3.X Hypervisor and Agents for RHEL-6.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm-rhev packages provide the user-space component for running virtual machines that use KVM in environments managed by Red Hat products.
Security Fix(es):
* Quick emulator (Qemu) built with the Cirrus CLGD 54xx VGA emulator support is vulnerable to an out-of-bounds access issue. It could occur while copying VGA data via bitblt copy in backward mode. A privileged user inside a guest could use this flaw to crash the Qemu process resulting in DoS or potentially execute arbitrary code on the host with privileges of Qemu process on the host. (CVE-2017-2615)
* An out-of-bounds read-access flaw was found in the QEMU emulator built with IP checksum routines. The flaw could occur when computing a TCP/UDP packet's checksum, because a QEMU function used the packet's payload length without checking against the data buffer's size. A user inside a guest could use this flaw to crash the QEMU process (denial of service). (CVE-2016-2857)
Red Hat would like to thank Wjjzhang (Tencent.com Inc.) Li Qiang (360.cn Inc.) for reporting CVE-2017-2615 and Ling Liu (Qihoo 360 Inc.) for reporting CVE-2016-2857.
