Synopsis

The remote Red Hat host is missing one or more security updates.

Description

The remote Redhat Enterprise Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2021:1189 advisory.

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.

Changes to the redhat-release-virtualization-host component:

* Previously, the redhat-support-tool was missing from the RHV-H 4.4 package.
In this release, the redhat-support-tool has been added. (BZ#1928607)

Security Fix(es):

* openssl: NULL pointer dereference in signature_algorithms processing (CVE-2021-3449)

* openssl: CA certificate check bypass with X509_V_FLAG_X509_STRICT (CVE-2021-3450)
