Description

A flaw was found in BusyBox. An integer overflow occurs in the volume_id component when calculating buffer boundaries while probing filesystem metadata. An attacker can exploit this vulnerability by providing a specially crafted filesystem image on an attached storage device. When probed by utilities such as blkid, findfs, or mount, the application crashes, resulting in a Denial of Service (DoS) that prevents the system from resolving or mounting storage devices.
