-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Important: Red Hat Virtualization Host security and bug fix update [ovirt-4.4.10] Async #1 Advisory ID: RHSA-2022:0841-01 Product: Red Hat Virtualization Advisory URL: https://access.redhat.com/errata/RHSA-2022:0841 Issue date: 2022-03-14 CVE Names: CVE-2021-0920 CVE-2021-4154 CVE-2022-0330 CVE-2022-0435 CVE-2022-0847 CVE-2022-22942 CVE-2022-24407 ==================================================================== 1. Summary: An update for 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 - x86_64 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): * kernel: improper initialization of the "flags" member of the new pipe_buffer (CVE-2022-0847) * kernel: Use After Free in unix_gc() which could result in a local privilege escalation (CVE-2021-0920) * kernel: local privilege escalation by exploiting the fsconfig syscall parameter leads to container breakout (CVE-2021-4154) * kernel: possible privileges escalation due to missing TLB flush (CVE-2022-0330) * kernel: remote stack overflow via kernel panic on systems using TIPC may lead to DoS (CVE-2022-0435) * kernel: failing usercopy allows for use-after-free exploitation (CVE-2022-22942) * cyrus-sasl: failure to properly escape SQL input allows an attacker to execute arbitrary SQL commands (CVE-2022-24407) 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. 4.
