Описание
Incus is a system container and virtual machine manager. Prior to version 7.3.0, an unprivileged, project-confined Incus user (a non-admin TLS/RBAC identity with can_create_images and can_create_instances) can execute arbitrary code as root on the host. A crafted image ships backup.yaml as a symlink to a host file. When the root daemon writes the instance's backup file, it follows the symlink. Version 7.3.0 patches the issue.
A flaw was found in Incus, a container and virtual machine manager. A crafted container image can trick the daemon into writing to arbitrary host files via a symlink in backup.yaml, potentially leading to root-level command execution on the host.
Отчет
Incus is not shipped in any Red Hat product. The community Fedora package is affected.
Меры по смягчению последствий
No mitigation is needed as Incus is not shipped in any Red Hat product.
