Pull Request Overview
This pull request introduces a sophisticated proof-of-concept exploit for CVE-2025-53367 that achieves code execution through the DjVuLibre vulnerability. The PR adds a complete exploit implementation that bypasses ASLR and demonstrates execution of arbitrary shell commands in PDF viewers like evince/papers.
- Replaces a simple crash-only proof-of-concept with a full code execution exploit
- Adds a comprehensive patch file that modifies the DjVuLibre codebase to generate exploit files
- Provides detailed build and usage instructions for different Linux distributions

The first copilot suggestion about a missing space should probably be implemented |
Add the poc that achieves code execution.
