          "details": "CVE-2019-19221 is a local, user‑interaction–dependent out‑of‑bounds read in libarchive 3.4.0 that manifests as a crash of the archiving tool (e.g., bsdtar) when it processes a specially crafted archive, with no confidentiality or integrity impact and no privilege escalation. The effect is limited to availability of the processing utility itself, not the host system or other services. In centrally managed server/VM environments where command‑line archivers only handle intentionally supplied files, the practical exploitation likelihood is low, so this can be safely deprioritized.",
