Upgrading?
AI Summary
This release hardens the parser against malicious PDFs by bounding resource usage for Form XObjects, CID ranges, and content-stream decoding. Additionally, it improves extraction quality for complex structures like Form XObjects and small-caps runs.
Key Highlights
- Caps resource usage for Form XObject expansion, CID ranges, and content-stream decode.
- Form XObjects now track text line matrix and honor spacing operators.
- Small-caps runs merge correctly instead of being read as table columns.
- Hardens parsing against crafted PDFs intended to cause denial-of-service.
New Features
- Hardened parsing against denial-of-service vectors
- Improved FormXObject text line matrix tracking
