Summary
Red Hat Security Advisory: Red Hat Virtualization Host 4.4.z SP 1 security update batch#4 (oVirt-4.5.3-4)

Notes

Topic
An update for redhat-release-virtualization-host and redhat-virtualization-host is now available for Red Hat Virtualization 4 for Red Hat Enterprise Linux 8. 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.
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 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. Security Fix(es): * kernel: i915: Incorrect GPU TLB flush can lead to random memory access (CVE-2022-4139) * libksba: integer overflow to code execution (CVE-2022-47629) * sudo: arbitrary file write with privileges of the RunAs user (CVE-2023-22809) 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.
