> 1. Unqiue Bugs Found
> Recently we (Zhang Cen, [https://github.com/occia] and Huang Wenjie [https://github.com/ZanderHuang]) discovered a series of bugs in latest pdfbox (3.0.0-alpha2).
> Every bug we reported in the following is unique and reproducable. Furthermore, they have been manually analyzed and triaged in removing the duplicates.
> Due to the lack of contextual knowledge in the pdfbox library, we cannot thoroughly fix some bugs hence we look forward to any proposed plan from the developers in fixing these bugs.
> 2. Bug Report and Crash Seeds
> The bug report folder can be downloaded from [https://drive.google.com/drive/folders/1TMOzudQOVXPKdZ1--NyusyV7kHRA2MSE?usp=sharing]
> It contains both reports and crash seeds.
> 3. Test Program to Reproduce Crashes
> The test program can be downloaded from [https://drive.google.com/file/d/1r0OsDC0vg8Qc-XtGg0XDKbxubaPozcBj/view?usp=sharing]
> Total 70 bugs are reported in this issue.

> - Level 3 (files): POC file and {*}{{*}}report.txt{{*}}{*} including reproducing steps
> 5. report.txt content:
> 1. Exception type
> 2. Error location
> 3. Bug cause and impact
> 4. Crash thread's stacks
> 5. Steps to reproduce
