Mageia 2020-0473: libvirt security update
Summary
A double free memory issue was found to occur in the libvirt API responsible
for requesting information about network interfaces of a running QEMU domain.
This flaw affects the polkit access control driver. Specifically, clients
connecting to the read-write socket with limited ACL permissions could use this
flaw to crash the libvirt daemon, resulting in a denial of service, or
potentially escalate their privileges on the system. The highest threat from
this vulnerability is to data confidentiality and integrity as well as system
availability (CVE-2020-25637).
