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 7.

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 7-based RHEV-H for RHEV 4 (build requirements) - noarch, x86_64
Red Hat Virtualization 4 Hypervisor for RHEL 7 - noarch

3. Description:

The redhat-virtualization-host packages provide the Red Hat Virtualization
Host.
These packages include redhat-release-virtualization-host. 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 unix_gc() which could result in a local
privilege escalation (CVE-2021-0920)

* 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: xfs: raw block device data leak in XFS_IOC_ALLOCSP IOCTL
(CVE-2021-4155)

* aide: heap-based buffer overflow on outputs larger than B64_BUF
(CVE-2021-45417)

* kernel: possible privileges escalation due to missing TLB flush
(CVE-2022-0330)

* openssl: Infinite loop in BN_mod_sqrt() reachable when parsing
certificates (CVE-2022-0778)

* 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)

* expat: Malformed 2- and 3-byte UTF-8 sequences can lead to arbitrary code
execution (CVE-2022-25235)

* expat: Namespace-separator characters in "xmlns[:prefix]" attribute
values can lead to arbitrary code execution (CVE-2022-25236)

* expat: Integer overflow in storeRawNames() (CVE-2022-25315)

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):

* RHV-H has been rebased on RHEL-7.9.z #13 (BZ#2048409)
