Summary
Red Hat Security Advisory: qemu-kvm-rhev security 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 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 and the VNC display driver support, is vulnerable to a heap buffer overflow issue. The issue could occur when a VNC client attempts to update its display after a VGA operation is performed by a guest. A privileged user/process inside guest could use this flaw to crash the QEMU process resulting in DoS or, potentially, leverage it to execute arbitrary code on the host with privileges of the QEMU process. (CVE-2016-9603)

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 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):
* A heap buffer overflow flaw was found in QEMU's Cirrus CLGD 54xx VGA emulator's VNC display driver support; the issue could occur when a VNC client attempted to update its display after a VGA operation is performed by a guest. A privileged user/process inside a guest could use this flaw to crash the QEMU process or, potentially, execute arbitrary code on the host with privileges of the QEMU process. (CVE-2016-9603)
* An out-of-bounds r/w access issue was found in QEMU's Cirrus CLGD 54xx VGA Emulator support. The vulnerability could occur while copying VGA data via various bitblt functions. A privileged user inside a guest could use this flaw to crash the QEMU process or, potentially, execute arbitrary code on the host with privileges of the QEMU process. (CVE-2017-7980)
* An out-of-bounds memory access issue was found in QEMU's VNC display driver support. The vulnerability could occur while refreshing the VNC display surface area in the 'vnc_refresh_server_surface'. A user/process inside a guest could use this flaw to crash the QEMU process, resulting in a denial of service. (CVE-2017-2633)
* An out-of-bounds access issue was found in QEMU's Cirrus CLGD 54xx VGA Emulator support. The vulnerability could occur while copying VGA data using bitblt functions (for example, cirrus_bitblt_rop_fwd_transp_). A privileged user inside a guest could use this flaw to crash the QEMU process, resulting in denial of service. (CVE-2017-7718)
Red Hat would like to thank Jiangxin (PSIRT Huawei Inc.) and Li Qiang (Qihoo 360 Gear Team) for reporting CVE-2017-7980 and Jiangxin (PSIRT Huawei Inc.) for reporting CVE-2017-7718.

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):
* A heap buffer overflow flaw was found in QEMU's Cirrus CLGD 54xx VGA emulator's VNC display driver support; the issue could occur when a VNC client attempted to update its display after a VGA operation is performed by a guest. A privileged user/process inside a guest could use this flaw to crash the QEMU process or, potentially, execute arbitrary code on the host with privileges of the QEMU process. (CVE-2016-9603)
* Quick Emulator (QEMU) built with the Cirrus CLGD 54xx VGA Emulator support is vulnerable to an out-of-bounds r/w access issue. The vulnerability could occur while copying VGA data via various bitblt functions. A privileged user inside the guest could use this flaw to crash the QEMU process (DoS) or potentially execute arbitrary code on a host with privileges of the host's QEMU process. (CVE-2017-7980)
* Quick Emulator (QEMU) built with the VNC display driver support is vulnerable to an out-of-bounds memory access issue. The vulnerability could occur while refreshing the VNC display surface area in the 'vnc_refresh_server_surface'. A user/process inside the guest could use this flaw to crash the QEMU process, resulting in a DoS. (CVE-2017-2633)
* Quick Emulator (QEMU) built with the Cirrus CLGD 54xx VGA Emulator support is vulnerable to an out-of-bounds access issue. The vulnerability could occur while copying VGA data using bitblt functions (for example, cirrus_bitblt_rop_fwd_transp_). A privileged user inside a guest could use this flaw to crash the QEMU process, resulting in DoS. (CVE-2017-7718)
Red Hat would like to thank Jiangxin (PSIRT Huawei Inc.) Li Qiang (Qihoo 360 Gear Team) for reporting CVE-2017-7980 and Jiangxin (PSIRT Huawei Inc.) for reporting CVE-2017-7718.

Summary
Red Hat Security Advisory: qemu-kvm-rhev security update
Notes
Topic
An update for qemu-kvm-rhev is now available for Red Hat OpenStack Platform 10.0 (Newton).
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 and the VNC display driver support, is vulnerable to a heap buffer overflow issue. The issue could occur when a VNC client attempts to update its display after a VGA operation is performed by a guest. A privileged user/process inside guest could use this flaw to crash the QEMU process resulting in DoS or, potentially, leverage it to execute arbitrary code on the host with privileges of the QEMU process. (CVE-2016-9603)

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 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 and the VNC display driver support, is vulnerable to a heap buffer overflow issue. The issue could occur when a VNC client attempts to update its display after a VGA operation is performed by a guest. A privileged user/process inside guest could use this flaw to crash the QEMU process resulting in DoS or, potentially, leverage it to execute arbitrary code on the host with privileges of the QEMU process. (CVE-2016-9603)

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):
* An out-of-bounds access issue was found in QEMU's Cirrus CLGD 54xx VGA Emulator support. The vulnerability could occur while copying VGA data using bitblt functions (for example, cirrus_bitblt_rop_fwd_transp_). A privileged user inside a guest could use this flaw to crash the QEMU process, resulting in denial of service. (CVE-2017-7718)
Red Hat would like to thank Jiangxin (PSIRT Huawei Inc.) for reporting
CVE-2017-7718.
Bug Fix(es):
* When using post-copy migration with the virtio Random Number Generator (RNG) device, virtio-rng continued generating data while the migration was already in post-copy mode. Consequently, the migration sometimes failed and the error message "Failed to load virtio-rng:virtio" was displayed. The source code has been improved and the problem no longer occurs in the scenario described. (BZ#1450375)

Summary
Red Hat Security Advisory: qemu-kvm security 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 package provides the user-space component for running virtual machines that use KVM.
Security Fix(es):
* A heap buffer overflow flaw was found in QEMU's Cirrus CLGD 54xx VGA emulator's VNC display driver support; the issue could occur when a VNC client attempted to update its display after a VGA operation is performed by a guest. A privileged user/process inside a guest could use this flaw to crash the QEMU process or, potentially, execute arbitrary code on the host with privileges of the QEMU process. (CVE-2016-9603)
* An out-of-bounds r/w access issue was found in QEMU's Cirrus CLGD 54xx VGA Emulator support. The vulnerability could occur while copying VGA data via various bitblt functions. A privileged user inside a guest could use this flaw to crash the QEMU process or, potentially, execute arbitrary code on the host with privileges of the QEMU process. (CVE-2017-7980)
* An out-of-bounds memory access issue was found in QEMU's VNC display driver support. The vulnerability could occur while refreshing the VNC display surface area in the 'vnc_refresh_server_surface'. A user/process inside a guest could use this flaw to crash the QEMU process, resulting in a denial of service. (CVE-2017-2633)
* An out-of-bounds access issue was found in QEMU's Cirrus CLGD 54xx VGA Emulator support. The vulnerability could occur while copying VGA data using bitblt functions (for example, cirrus_bitblt_rop_fwd_transp_). A privileged user inside a guest could use this flaw to crash the QEMU process, resulting in denial of service. (CVE-2017-7718)
Red Hat would like to thank Jiangxin (PSIRT Huawei Inc.) and Li Qiang (Qihoo 360 Gear Team) for reporting CVE-2017-7980 and Jiangxin (PSIRT Huawei Inc.) for reporting CVE-2017-7718.

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 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 package provides the user-space component for running virtual machines that use KVM.
Security Fix(es):
* An out-of-bounds r/w access issue was found in QEMU's Cirrus CLGD 54xx VGA Emulator support. The vulnerability could occur while copying VGA data via various bitblt functions. A privileged user inside a guest could use this flaw to crash the QEMU process or, potentially, execute arbitrary code on the host with privileges of the QEMU process. (CVE-2017-7980)
* An out-of-bounds access issue was found in QEMU's Cirrus CLGD 54xx VGA Emulator support. The vulnerability could occur while copying VGA data using bitblt functions (for example, cirrus_bitblt_rop_fwd_transp_). A privileged user inside a guest could use this flaw to crash the QEMU process, resulting in denial of service. (CVE-2017-7718)
Red Hat would like to thank Jiangxin (PSIRT Huawei Inc) and Li Qiang (Qihoo 360 Gear Team) for reporting CVE-2017-7980 and Jiangxin (PSIRT Huawei Inc) for reporting CVE-2017-7718.
Bug Fix(es):
* Previously, guest virtual machines in some cases became unresponsive when the "pty" back end of a serial device performed an irregular I/O communication. This update improves the handling of serial I/O on guests, which prevents the described problem from occurring. (BZ#1452332)

The qemu-kvm package provides the user-space component for running virtual machines that use KVM.\n\nSecurity Fix(es):\n\n* An out-of-bounds r/w access issue was found in QEMU\u0027s Cirrus CLGD 54xx VGA Emulator support. The vulnerability could occur while copying VGA data via various bitblt functions. A privileged user inside a guest could use this flaw to crash the QEMU process or, potentially, execute arbitrary code on the host with privileges of the QEMU process. (CVE-2017-7980)\n\n* An out-of-bounds access issue was found in QEMU\u0027s Cirrus CLGD 54xx VGA Emulator support. The vulnerability could occur while copying VGA data using bitblt functions (for example, cirrus_bitblt_rop_fwd_transp_). A privileged user inside a guest could use this flaw to crash the QEMU process, resulting in denial of service. (CVE-2017-7718)\n\nRed Hat would like to thank Jiangxin (PSIRT Huawei Inc) and Li Qiang (Qihoo 360 Gear Team) for reporting CVE-2017-7980 and Jiangxin (PSIRT Huawei Inc) for reporting CVE-2017-7718.\n\nBug Fix(es):\n\n* Previously, guest virtual machines in some cases became unresponsive when the \"pty\" back end of a serial device performed an irregular I/O communication. This update improves the handling of serial I/O on guests, which prevents the described problem from occurring. (BZ#1452332)",

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 7.0 (Kilo) 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 and the VNC display driver support, is vulnerable to a heap buffer overflow issue. The issue could occur when a VNC client attempts to update its display after a VGA operation is performed by a guest. A privileged user/process inside guest could use this flaw to crash the QEMU process resulting in DoS or, potentially, leverage it to execute arbitrary code on the host with privileges of the QEMU process. (CVE-2016-9603)

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 6.0 (Juno) 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 and the VNC display driver support, is vulnerable to a heap buffer overflow issue. The issue could occur when a VNC client attempts to update its display after a VGA operation is performed by a guest. A privileged user/process inside guest could use this flaw to crash the QEMU process resulting in DoS or, potentially, leverage it to execute arbitrary code on the host with privileges of the QEMU process. (CVE-2016-9603)

Summary
Red Hat Security Advisory: qemu-kvm-rhev security 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 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 and the VNC display driver support, is vulnerable to a heap buffer overflow issue. The issue could occur when a VNC client attempts to update its display after a VGA operation is performed by a guest. A privileged user/process inside guest could use this flaw to crash the QEMU process resulting in DoS or, potentially, leverage it to execute arbitrary code on the host with privileges of the QEMU process.
