"The libgovirt packages contain a library that allows applications to
use the oVirt Representational State Transfer (REST) API to list
virtual machines (VMs) managed by an oVirt instance. The library is
also used to get the connection parameters needed to establish a
connection to the VMs using Simple Protocol For Independent Computing
Environments (SPICE) or Virtual Network Computing (VNC).

The spice-vdagent packages provide a SPICE agent for Linux guests.

The virt-viewer packages provide Virtual Machine Viewer, which is a
lightweight interface for interacting with the graphical display of a
virtualized guest.

Security Fix(es) :

  - spice-client: Insufficient encoding checks for LZ can
    cause different integer/buffer overflows
    (CVE-2018-10893)");
