Summary
Red Hat Security Advisory: qemu-kvm security 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 packages provide the user-space component for running virtual machines that use KVM.
Security Fix(es):
* QEMU: slirp: heap buffer overflow in tcp_emu() (CVE-2019-6778)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

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 Virtualization for Red Hat Virtualization Host 7.
Red Hat Product Security has rated this update as having a Important security impact. 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):
* CVE-2018-20815 QEMU: device_tree: heap buffer overflow while loading device tree blob
* CVE-2019-6778 QEMU: slirp: heap buffer overflow in tcp_em
This update fixes the following bug:
* 1705364 RHV VM pauses when 'dd' issued inside guest to a direct lun configured as virtio-scsi with scsi-passthrough
Users of qemu-kvm are advised to upgrade to these updated packages. 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
An update for qemu-kvm-rhev is now available for Red Hat OpenStack Platform 10.0 (Newton), Red Hat OpenStack Platform 13.0 (Queens), and Red Hat OpenStack Platform 14.0 (Rocky).
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):
* QEMU: slirp: heap buffer overflow in tcp_emu() (CVE-2019-6778)
* QEMU: rtl8139: integer overflow leads to buffer overflow (CVE-2018-17958)
* QEMU: net: ignore packets with large size (CVE-2018-17963)
* QEMU: seccomp: blacklist is not applied to all threads (CVE-2018-15746)
* QEMU: scsi-generic: possible OOB access while handling inquiry request (CVE-2019-6501)
* QEMU: slirp: information leakage in tcp_emu() due to uninitialized stack variables (CVE-2019-9824)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Bug Fix(es):
* Update qemu-kvm-rhev for RHEL 7.7 compatibility [OSP-14] (BZ#1728358)
* Update qemu-kvm-rhev for RHEL 7.7 compatibility [OSP-13] (BZ#1728359)

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 packages provide the user-space component for running virtual machines that use KVM.
Security Fix(es):
* QEMU: slirp: heap buffer overflow while reassembling fragmented datagrams (CVE-2018-11806)
* QEMU: slirp: heap buffer overflow in tcp_emu() (CVE-2019-6778)
* QEMU: ne2000: integer overflow leads to buffer overflow issue (CVE-2018-10839)
* QEMU: pcnet: integer overflow leads to buffer overflow (CVE-2018-17962)
* QEMU: qxl: null pointer dereference while releasing spice resources (CVE-2019-12155)
