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: Adjust max memlock on mdev hotplug (bsc#1177480).
Xen: Don’t add dom0 twice on driver reload (bsc#1176430).
Fixed an issue where building was failing (bsc#1175574).
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.
