"From Red Hat Security Advisory 2019:1579 :

An update for libvirt is now available 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.

The libvirt library contains a C API for managing and interacting with
the virtualization capabilities of Linux and other operating systems.
In addition, libvirt provides tools for remote management of
virtualized systems.

Security Fix(es) :

* libvirt: arbitrary file read/exec via virDomainSaveImageGetXMLDesc
API (CVE-2019-10161)

* libvirt: virDomainManagedSaveDefineXML API exposed to readonly
clients (CVE-2019-10166)

* libvirt: arbitrary command execution via
virConnectGetDomainCapabilities API (CVE-2019-10167)

* libvirt: arbitrary command execution via
virConnectBaselineHypervisorCPU and virConnectCompareHypervisorCPU
APIs (CVE-2019-10168)

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) :

* Live migration fail with unsafe error when GPFS is used as shared
filesystem (BZ#1715867)"
