"This update for libvirt fixes the following issues :

CVE-2020-15708: Added a note to libvirtd.conf about polkit auth in
SUSE distros (bsc#1174955).

CVE-2020-25637: Fixed a double free in qemuAgentGetInterfaces()
(bsc#1177155).

qemu: Avoid stale capabilities cache host CPU or kernel command line
changes (bsc#1173157).

virdevmapper: Handle kernel without device-mapper support
(bsc#1175465).

Xen: Added support for passing arbitrary commands to the qemu device
model, similar to the xl.cfg(5) device_model_args setting
(bsc#1174139).

Xen: Don't add dom0 twice on driver reload (bsc#1176430).

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
