          "details": "This vulnerability is a denial‑of‑service in Poppler’s Type 1C font parsing that only triggers when a user or batch job opens a specially crafted PDF, requires user interaction, and has no confidentiality or integrity impact. The crash is confined to the unprivileged PDF‑processing application/library, and Poppler is not a network‑exposed service by default, so “remote” exploitation amounts to delivering a malicious file that merely terminates the processing task. In server/VM environments where PDF handling is not exposed as a service, the practical impact is limited to a transient process crash, making this a low‑priority issue.",
