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)

This issue causes an out-of-bands write during packet handling, compromising data integrity, confidentiality issues, a denial of service, and remote code execution.", title: "Vulnerability description", }, { category: "summary", text: "grub2: Integer underflow in grub_net_recv_ip4_packets", title: "Vulnerability summary", }, { category: "general", text: "The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.", title: "CVSS score applicability", }, ], product_status: { fixed: [ "8Base-RHV-Hypervisor-4:redhat-virtualization-host-0:4.5.1-202207170705_8.6.src", "8Base-RHV-Hypervisor-4:redhat-virtualization-host-image-update-0:4.5.1-202207170705_8.6.x86_64", ], known_not_affected: [ "8Base-RHV-HypervisorBuild-4:redhat-release-virtualization-host-0:4.5.1-1.el8ev.src", "8Base-RHV-HypervisorBuild-4:redhat-release-virtualization-host-0:4.5.1-1.el8ev.x86_64", "8Base-RHV-HypervisorBuild-4:redhat-release-virtualization-host-content-0:4.5.1-1.el8ev.x86_64", "8Base-RHV-HypervisorBuild-4:redhat-virtualization-host-image-update-placeholder-0:4.5.1-1.el8ev.noarch", "8Base-RHV-HypervisorBuild-4:redhat-virtualization-host-productimg-0:4.5.1-1.el8.src", "8Base-RHV-HypervisorBuild-4:redhat-virtualization-host-productimg-0:4.5.1-1.el8.x86_64", ], }, references: [ { category: "self", summary: "Canonical URL", url: "https://access.redhat.com/security/cve/CVE-2022-28733", }, { category: "external", summary: "RHBZ#2083339", url: "https://bugzilla.redhat.com/show_bug.cgi?id=2083339", }, { category: "external", summary: "https://www.cve.org/CVERecord?id=CVE-2022-28733", url: "https://www.cve.org/CVERecord?id=CVE-2022-28733", }, { category: "external", summary: "https://nvd.nist.gov/vuln/detail/CVE-2022-28733", url: "https://nvd.nist.gov/vuln/detail/CVE-2022-28733", }, ], release_date: "2022-06-07T00:00:00+00:00", remediations: [ { category: "vendor_fix", date: "2022-07-21T12:34:16+00:00", details: "For details on how to apply this update, which includes the changes described in this advisory, refer to:\n\nhttps://access.redhat.com/articles/2974891", product_ids: [ "8Base-RHV-Hypervisor-4:redhat-virtualization-host-0:4.5.1-202207170705_8.6.src", "8Base-RHV-Hypervisor-4:redhat-virtualization-host-image-update-0:4.5.1-202207170705_8.6.x86_64", ], restart_required: { category: "none", }, url: "https://access.redhat.com/errata/RHSA-2022:5678", }, ], scores: [ { cvss_v3: { attackComplexity: "HIGH", attackVector: "NETWORK", availabilityImpact: "HIGH", baseScore: 8.1, baseSeverity: "HIGH", confidentialityImpact: "HIGH", integrityImpact: "HIGH", privilegesRequired: "NONE", scope: "UNCHANGED", userInteraction: "NONE", vectorString: "CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H", version: "3.1", }, products: [ "8Base-RHV-Hypervisor-4:redhat-virtualization-host-0:4.5.1-202207170705_8.6.src", "8Base-RHV-Hypervisor-4:redhat-virtualization-host-image-update-0:4.5.1-202207170705_8.6.x86_64", ], }, ], threats: [ { category: "impact", details: "Important", }, ], title: "grub2: Integer underflow in grub_net_recv_ip4_packets", }, ], }
