1. Summary:
An update for redhat-release-virtualization-host,
redhat-virtualization-host, and redhat-virtualization-host-productimg is
now available for Red Hat Virtualization 4 for Red Hat Enterprise Linux 8.
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.
2. Relevant releases/architectures:
RHEL 8-based RHEV-H for RHEV 4 (build requirements) - noarch, x86_64
Red Hat Virtualization 4 Hypervisor for RHEL 8 - x86_64
3. Description:
The redhat-virtualization-host packages provide the Red Hat Virtualization
Host. These packages include redhat-release-virtualization-host,
ovirt-node, and rhev-hypervisor. Red Hat Virtualization Hosts (RHVH) are
installed using a special build of Red Hat Enterprise Linux with only the
packages required to host virtual machines. RHVH features a Cockpit user
interface for monitoring the host's resources and performing administrative
tasks.
The ovirt-node-ng packages provide the Red Hat Virtualization Host. These
packages include redhat-release-virtualization-host, ovirt-node, and
rhev-hypervisor. Red Hat Virtualization Hosts (RHVH) are installed using a
special build of Red Hat Enterprise Linux with only the packages required
to host virtual machines. RHVH features a Cockpit user interface for
monitoring the host's resources and performing administrative tasks.
The following packages have been upgraded to a later upstream version:
redhat-release-virtualization-host (4.5.2), redhat-virtualization-host
(4.5.2), redhat-virtualization-host-productimg (4.5.2). (BZ#2070049,
BZ#2093195)
Security Fix(es):
* kernel: Small table perturb size in the TCP source port generation
algorithm can lead to information leak (CVE-2022-1012)
* dpdk: DoS when a Vhost header crosses more than two descriptors and
exhausts all mbufs (CVE-2022-2132)
* systemd-resolved: use-after-free when dealing with DnsStream in
resolved-dns-stream.c (CVE-2022-2526)
* kernel: a use-after-free in cls_route filter implementation may lead to
privilege escalation (CVE-2022-2588)
* rsync: remote arbitrary files write inside the directories of connecting
peers (CVE-2022-29154)
* kernel: a use-after-free write in the netfilter subsystem can lead to
privilege escalation to root (CVE-2022-32250)
