In Red Hat Enterprise Linux, BusyBox is not used as the standard user-space archive extractor, limiting exposure to specialized environments such as rescue tools or recovery images. Additionally, successful impact relies on linking external target files into the destination path followed by a separate overwriting operation, constraining practical exploitability in default deployments.", "threat_severity": "Moderate"}
