Summary
Red Hat Security Advisory: Red Hat Virtualization security, bug fix, and enhancement update [ovirt-4.5.1]

Notes

Topic
An update for imgbased, redhat-release-virtualization-host, and redhat-virtualization-host 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.
Details
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 following packages have been upgraded to a later upstream version: redhat-release-virtualization-host (4.5.1), redhat-virtualization-host (4.5.1), redhat-virtualization-host-productimg (4.5.1). (BZ#2062192, BZ#2070869, BZ#2094682) Security Fix(es): * kernel: buffer overflow in IPsec ESP transformation code (CVE-2022-27666) * grub2: Integer underflow in grub_net_recv_ip4_packets (CVE-2022-28733) 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): * RHV-H 4.4 SP1 Has been rebased on RHEL 8.6 Batch #1 (BZ#2070869)
