Summary
Red Hat Security Advisory: Red Hat Virtualization Host security and enhancement update [ovirt-4.4.10] Async #2

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. 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. Security Fix(es): * expat: Malformed 2- and 3-byte UTF-8 sequences can lead to arbitrary code execution (CVE-2022-25235) * expat: Namespace-separator characters in "xmlns[:prefix]" attribute values can lead to arbitrary code execution (CVE-2022-25236) * expat: Integer overflow in storeRawNames() (CVE-2022-25315) 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): * Red Hat Virtualization Host was rebased on Red Hat Enterprise Linux 8.5.0.3. (BZ#2048407) * Rebase package(s) to version: libvirt-7.6.0-6.1.module+el8.5.0+14474+b3410d40 Highlights and important bug fixes: consume libvirt fix for failure to connect socket to '/run/libvirt/virtlogd-sock' - possibly caused by too many open files from libvirtd. (BZ#2057048)
