RedHat: RHSA-2022-8598:01 Important: Red Hat Virtualization Host security
Summary
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.
The ovirt-node-ng 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.
The following packages have been upgraded to a later upstream version:
redhat-release-virtualization-host (4.5.2), redhat-virtualization-host
(4.5.2), redhat-virtualization-host-productimg (4.5.2). (BZ#2070049,
BZ#2093195)
Security Fix(es):
* libksba: integer overflow may lead to remote code execution
(CVE-2022-3515)
* bind: memory leak in ECDSA DNSSEC verification code (CVE-2022-38177)
* bind: memory leaks in EdDSA DNSSEC verification code (CVE-2022-38178)
* expat: a use-after-free in the doContent function in xmlparse.c
(CVE-2022-40674)
* device-mapper-multipath: Authorization bypass, multipathd daemon listens
