Summary
Red Hat Security Advisory: Red Hat Virtualization Host security update [ovirt-4.5.3-1]

Notes

Topic
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.
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. 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): * libksba: integer overflow may lead to remote code execution (CVE-2022-3515) * bind: memory leak in ECDSA DNSSEC verification code (CVE-2022-38177) * bind: memory leaks in EdDSA DNSSEC verification code (CVE-2022-38178) * expat: a use-after-free in the doContent function in xmlparse.c (CVE-2022-40674) * device-mapper-multipath: Authorization bypass, multipathd daemon listens for client connections on an abstract Unix socket (CVE-2022-41974) 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.
