How to fix?

There is no fixed version for Debian:unstable busybox.

NVD Description

Note: Versions mentioned in the description apply only to the upstream busybox package and not the busybox package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

A flaw was found in BusyBox's mount utility. A non-root user can bypass mount security restrictions set in /etc/fstab by specifying clearing-mask options on the command line. These options pass the non-root flag filter and are merged with fstab options as strings; when the combined options are re-parsed, clearing options can override nosuid, nodev, and noexec protections the administrator intended to enforce.
