Summary
Red Hat Security Advisory: Red Hat Virtualization security, bug fix, and enhancement update

Notes

Topic
An update for cockpit-ovirt, redhat-release-virtualization-host, redhat-virtualization-host, and v2v-conversion-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 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: cockpit-ovirt (0.14.15), redhat-release-virtualization-host (4.4.3), redhat-virtualization-host (4.4.3), v2v-conversion-host (1.16.2). (BZ#1898023, BZ#1902301, BZ#1907539) Security Fix(es): * lldpd: buffer overflow in the lldp_decode function in daemon/protocols/lldp.c (CVE-2015-8011) * nodejs-lodash: prototype pollution in zipObjectDeep function (CVE-2020-8203) 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. 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): * Previously, upgrade from Red Had Virtualization (RHV) 4.4.1 to RHV 4.4.2 failed due to dangling symlinks from the iSCSI Storage Domain that weren't cleaned up. In this release, the upgrade succeeds. (BZ#1895356) * Previously, when migrating a Windows virtual machine from a VMware environment to Red Hat Virtualization 4.4.3, the migration failed due to a file permission error. In this release, the migration succeeds. (BZ#1901423)
