Summary: 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 Moderate. 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. 2. Relevant releases/architectures: RHEL 8-based RHEV-H for RHEV 4 (build requirements) - noarch, x86_64 Red Hat Virtualization 4 Hypervisor for RHEL 8 - x86_64 Red Hat Virtualization 4 Management Agent for RHEL 7 Hosts - noarch 3. Description: 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 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): * python-cryptography: bleichenbacher timing oracle attack against RSA decryption (CVE-2020-25659) * krb5: unbounded recursion via an ASN.1-encoded Kerberos message in lib/krb5/asn.1/asn1_encode.c may lead to DoS (CVE-2020-28196) * python-cryptography: certain sequences of update() calls when symmetrically encrypting very large payloads could result in an integer overflow and lead to buffer overflows (CVE-2020-36242) For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section. Bug Fix(es): * Previously, old RPM files were not properly removed during package removal (uninistall) or upgrade. As a result, removed packages were reinstalled, or, during and upgrade, the system tried to install two or more different versions at once, causing the upgrade to fail. In this release, the dnf plugin has been fixed, and RPM packages are now properly removed. The new version will also auto-heal the broken system by removing RPM packages which are not supposed to be in the persisted-rpms directory. (BZ#1936972) * With this release, ovirt-hosted-engine-ha supports multiple, comma-separated values for all iSCSI configuration items. (BZ#1909888) 4.
