Andreas Lehmkühler commented on PDFBOX-3545:
--------------------------------------------
The out of range startxref value wasn't the issue here, PDFBox is able to fix
that. But at least the pdf [~tilman] attached is malformed. The trailer at the
end of the pdf lacks of a root object. I've added a check for the root object.
The trailer is rebuilt If it isn't present.
> COSParser.parseXref failing if startXrefOffset over pdf size

> Key: PDFBOX-3545
> URL: https://issues.apache.org/jira/browse/PDFBOX-3545
> Project: PDFBox
> Issue Type: Bug
> Affects Versions: 2.0.3
> Reporter: Matus Zamborsky

>
> Any PDF which had wrong startxref was parsed with warning in PdfBox 1.8
> thanks to self healing mechanism.
> In version 2.0 the COSParser.parseXref (called from PDFParser) tries to seek
> to the startxref position.
> If the position is wrong, but within the file size, the PDF is parsed with
> warning.
> But when the startxref is over the file size, the parsing ended with
> exception.
> We could either test if startxref is not over source.length(), or catch the
> exception.
