  1. Description:

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: VNC: improper I/O watch removal in TLS handshake can lead to remote
    unauthenticated denial of service (CVE-2023-3354)

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):

  • [qemu-kvm] rhel guest failed boot with multi disks on error Failed to
    start udev Wait for Complete Device Initialization (BZ#2211923)

  • [rhel9.2] hotplug/hotunplug mlx vdpa device to the occupied addr port,
    then qemu core dump occurs after shutdown guest (BZ#2227721)

  1. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

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.

Red Hat OpenShift Virtualization release 4.13.4 is now available with updates to packages and images that fix several bugs and add enhancements. 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.This content is licensed under the Creative Commons Attribution 4.0 International License (https://creativecommons.org/licenses/by/4.0/).

Related CVEs: * CVE-2022-41723: A flaw was found in golang. A maliciously crafted HTTP/2 stream could cause excessive CPU consumption in the HPACK decoder, sufficient to cause a denial of service from a small number of requests.

CVE-2023-3354: Invalid Bug ID

A flaw was found in the QEMU built-in VNC server. When a client connects to the VNC server, QEMU checks whether the current number of connections crosses a certain threshold and if so, cleans up the previous connection. If the previous connection happens to be in the handshake phase and fails, QEMU cleans up the connection again, resulting in a NULL pointer dereference issue. This could allow a remote unauthenticated client to cause a denial of service.
