NVD Description

Note: Versions mentioned in the description apply only to the upstream kubevirt-virt-controller-fips-1.6 package and not the kubevirt-virt-controller-fips-1.6 package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

A flaw was found in KubeVirt's virt-handler network cache handling. The WriteToCachedFile function writes data to a launcher-rooted path using os.WriteFile and os.Chown without symlink protection. A user with access to the virt-launcher container can plant a symlink at the cache file path, causing virt-handler to follow it and overwrite an arbitrary host file with JSON content and change its ownership.
