          "details": "CVE-2025-1632 is a NULL‑pointer dereference in libarchive’s bsdunzip utility (≤3.7.7) that only causes the bsdunzip process to crash, with no confidentiality or integrity impact and no code execution or privilege escalation. Exploitation is local-only and requires a user to run bsdunzip on a crafted archive; the utility is not network-exposed and is typically a standalone tool rather than a background service. In centrally managed server and VM environments where archive tools are not executed on untrusted input by default, this amounts to a one-off denial‑of‑service of a userland command, making it safe to deprioritize.",
