CVE-2018-6764 (opens in a new tab)How to fix?
Upgrade Debian:12 libvirt to version 4.0.0-2 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libvirt package and not the libvirt package as distributed by Debian.
See How to fix? for Debian:12 relevant fixed versions and status.
util/virlog.c in libvirt does not properly determine the hostname on LXC container startup, which allows local guest OS users to bypass an intended container protection mechanism and execute arbitrary commands via a crafted NSS module.
