Resolution: Duplicate
> Limit maximum number of nesting levels for COSArrays/COSDictionaries
> --------------------------------------------------------------------
>
> Key: PDFBOX-5578
> URL: https://issues.apache.org/jira/browse/PDFBOX-5578
> Project: PDFBox
> Issue Type: Bug
> Components: Parsing
> Affects Versions: 2.0.27, 3.0.0 PDFBox
> Reporter: Andreas Lehmkühler
> Assignee: Andreas Lehmkühler
> Priority: Major
> Attachments: 2023_StackOverFlowtest.pdf
>
>
> The PDFBox user Jay filed an issue with the attached pdf using
> [email protected]
> It is a handcrafted pdf containing a COSArray with a lot of nesting levels
> which leads to a StackOverflowException.
> Theoretically there is no maximum nesting level for COSArrays or
> COSDictionaries but in the wild just a few number of levels may occur. Saying
> that, it makes sense to introduce a maximum number of nesting levels to avoid
> such exceptions
