          "details": "This issue is a local-only out-of-bounds read in bsdtar that triggers specifically when input is supplied via a pipe, requiring an authenticated user to craft and execute the piped command—there is no remote attack surface and user interaction is required. As an over-read (not a write), its practical impact is limited to a transient crash or at most minor leakage of process memory, with no integrity impact or code execution path. In typical server/VM environments where bsdtar runs on demand rather than as a persistent service, any failure is contained to the invoking session, making this a low-priority concern compared to network-exploitable or privilege‑escalating vulnerabilities.",
