-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Important: Red Hat Virtualization security, bug fix, and enhancement update [ovirt-4.5.0] Advisory ID: RHSA-2022:4896-01 Product: Red Hat Virtualization Advisory URL: https://access.redhat.com/errata/RHSA-2022:4896 Issue date: 2022-06-03 CVE Names: CVE-2018-25032 CVE-2021-4028 CVE-2021-4083 CVE-2022-0778 CVE-2022-1271 CVE-2022-24903 CVE-2022-25636 ==================================================================== 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 - 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: use-after-free in RDMA listen() (CVE-2021-4028) * kernel: fget: check that the fd still exists after getting a ref to it (CVE-2021-4083) * kernel: heap out of bounds write in nf_dup_netdev.c (CVE-2022-25636) * openssl: Infinite loop in BN_mod_sqrt() reachable when parsing certificates (CVE-2022-0778) * zlib: A flaw found in zlib when compressing (not decompressing) certain inputs (CVE-2018-25032) * gzip: arbitrary-file-write vulnerability (CVE-2022-1271) * rsyslog: Heap-based overflow in TCP syslog server (CVE-2022-24903) 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 Fixes: * elfutils package has been update within RHV-H Channel to match the same version released in RHEL (BZ#2038081) * Rebase package(s) to version 1.2.24 For highlights, important fixes, or notable enhancements: see bugs in "Depend On". (BZ#2057338) * Rebase package(s) to version: 4.5.0 Highlights, important fixes, or notable enhancements: (BZ#2057342) * Rebase package(s) to version anaconda-33.16.6.6-1.el8 For highlights and important bug fixes: include UI change for blocking installation if root password is not set. (BZ#1899821) * Red hat Virtualization Host has been rebased on Red Hat Enterprise Linux 8.6 (BZ#1997074) * Previously, concurrent executions of LV refresh (lvchange) failed. This hindered simultaneous starts of virtual machines that have thin-provisioned disks based on the same disk on a block storage domain. In this release, concurrent execution of LV refresh has been fixed in LVM2. (BZ#2020497) * Red Hat Virtualization Host has been rebased on latest Ceph 4.3 (BZ#2090138) * In previous releases systemtap package could have been installed on top of RHV-H from RHV-H channel. With 4.4 SP1 systemtap package installation is not supported anymore (BZ#2052963) 4.
