Synopsis

The remote Red Hat host is missing one or more security updates for redhat-virtualization-host.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:0457 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.

The following packages have been upgraded to a later upstream version: redhat-release-virtualization-host (4.2), redhat-virtualization-host (4.2). (BZ#1678629, BZ#1679414)

Security Fix(es):

* spice: Off-by-one error in array access in spice/server/memslot.c (CVE-2019-3813)

* systemd: Insufficient input validation in bus_process_object() resulting in PID 1 crash (CVE-2019-6454)

* vdsm: privilege escalation to root via systemd_run (CVE-2019-3831)
