This repository contains a proof-of-concept (PoC) exploit for a denial-of-service vulnerability in Poppler (before version 25.07.0), specifically targeting the pdfseparate utility. The exploit consists of a single malicious PDF file ('poppler-pdfseparate-poc') crafted to contain a self-referencing /Annots dictionary, which triggers infinite recursion in Poppler's annotation processing logic. When the vulnerable pdfseparate utility processes this file, it results in a stack overflow and application crash (as demonstrated in the included GDB backtrace in the README). The README provides a detailed explanation of the vulnerability, reproduction steps, and links to the vendor's patch and issue tracker. The exploit does not provide code execution or privilege escalation, but reliably causes a denial-of-service. The repository structure is minimal, containing only the PoC PDF and documentation.
