Summary
Red Hat Security Advisory: qemu-kvm-ma security update
Notes
Topic
An update for qemu-kvm-ma 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 a variety of architectures. The qemu-kvm-ma packages provide the user-space component for running virtual machines that use KVM on the IBM z Systems, IBM Power, and 64-bit ARM architectures.
Security Fix(es):
* QEMU: seccomp: blacklist is not applied to all threads (CVE-2018-15746)
* QEMU: vnc: memory leakage upon disconnect (CVE-2019-20382)
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, bug fix, and enhancement update
Notes
Topic
An update for qemu-kvm-rhev is now available for Red Hat Virtualization 4 for Red Hat Enterprise Linux 7 and Red Hat Virtualization Engine 4.3.
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
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-2019-20382 QEMU: vnc: memory leakage upon disconnect
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):
* Add support for newer glusterfs (BZ#1802216)
* Backport: Passthrough host CPU microcode version to KVM guest if using CPU passthrough to RHEL 7.7/7.8 (BZ#1791653)
* After hot unplug virtio-net and vfio nic, hot plug vfio-pci device fails in Win2019 guest (BZ#1721403)
* qemu-kvm-rhev: Qemu: seccomp: blacklist is not applied to all threads (BZ#1618504)
* Fix overzealous I/O request splitting performance regression (BZ#1819253)

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)
* Update qemu-kvm-rhev for RHEL 7.7 compatibility [OSP-10] (BZ#1728360)
