-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Important: Red Hat Virtualization Host security bug fix and enhancement update [ovirt-4.4.4] Advisory ID: RHSA-2021:0401-01 Product: Red Hat Virtualization Advisory URL: https://access.redhat.com/errata/RHSA-2021:0401 Issue date: 2021-02-03 CVE Names: CVE-2020-25684 CVE-2020-25685 CVE-2020-25686 CVE-2021-3156 ==================================================================== 1. 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 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. 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 - noarch, 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. Security Fix(es): * sudo: Heap buffer overflow in argument parsing (CVE-2021-3156) * dnsmasq: loose address/port check in reply_query() makes forging replies easier for an off-path attacker (CVE-2020-25684) * dnsmasq: loose query name check in reply_query() makes forging replies easier for an off-path attacker (CVE-2020-25685) * dnsmasq: multiple queries forwarded for the same name makes forging replies easier for an off-path attacker (CVE-2020-25686) 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, the Red Hat Virtualization Host (RHV-H) repository (rhvh-4-for-rhel-8-x86_64-rpms) did not include the libsmbclient package, which is a dependency for the sssd-ad package. Consequently, the sssd-ad package failed to install. With this update, the libsmbclient is now in the RHV-H repository, and sssd-ad now installs on RHV-H. (BZ#1868967) 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/2974891 After installing this update, the smb service will be restarted automatically. 5. Bugs fixed (https://bugzilla.redhat.com/): 1850939 - Hosted engine deployment does not properly show iSCSI LUN errors 1868967 - sssd-ad installation fails on RHV-H 4.4 due to missing libsmbclient from samba package in rhvh-4-for-rhel-8-x86_64-rpms channel 1889686 - CVE-2020-25684 dnsmasq: loose address/port check in reply_query() makes forging replies easier for an off-path attacker 1889688 - CVE-2020-25685 dnsmasq: loose query name check in reply_query() makes forging replies easier for an off-path attacker 1890125 - CVE-2020-25686 dnsmasq: multiple queries forwarded for the same name makes forging replies easier for an off-path attacker 1902315 - Rebase RHV-H 4.4 to RHV 4.4.4 1902646 - ssh connection fails due to overly permissive openssh.config file permissions 1909644 - HE deploy failed with "Failed to download metadata for repo 'rhel-8-for-x86_64-baseos-beta-rpms': Cannot download repomd.xml 1917684 - CVE-2021-3156 sudo: Heap buffer overflow in argument parsing 1921553 - RHVH upgrade to the latest 4.4.4-1 build will fail due to FileNotFoundError 1923126 - Hosted Engine setup fails on storage selection - Retrieval of iSCSI targets failed. 6.
