high Nessus Plugin ID 161818

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

The remote Redhat Enterprise Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2022:4896 advisory.

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)

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)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution
