Andreas Lehmkühler created PDFBOX-5177:
------------------------------------------

             Summary: Optimize memory footprint of PDFObjectStreamParser
                 Key: PDFBOX-5177
                 URL: https://issues.apache.org/jira/browse/PDFBOX-5177
             Project: PDFBox
          Issue Type: Improvement
          Components: Parsing
    Affects Versions: 2.0.23, 3.0.0 PDFBox
            Reporter: Andreas Lehmkühler
            Assignee: Andreas Lehmkühler
             Fix For: 2.0.24, 3.0.0 PDFBox


PDFObjectStreamParser uses the number of objects {{/N}} from the dictionary to initialize the map for object numbers/offsets (3.0.0) or list of objects (2.0-branch), but sometimes the value is too big or the stream can't be read, This may lead to a memory issue if resources are limited.
