[jira] [Commented] (PDFBOX-5178) Parsing differences between 2.0.23 and 2.0.24/3.0

["Andreas Lehmkühler (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PDFBOX-5178?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17655671#comment-17655671 ] 

Andreas Lehmkühler commented on PDFBOX-5178:
--------------------------------------------

I've added support for the index of the objects within a compressed object stream. But it is limited to those streams where the object numbers aren't unique as in the given file. But this doesn't fix the issue. PDFBox accidentally refers to the correct object. The issue was introduced when I "optimized" the parser to stop reading malformed dictionaries to avoid endless loops. I'm still searching for the correct ticket. BTW, 2.0.24 is affected as well.

> There are some weird differences in parsing the attached file, 2.0.23 shows "BigTIFF.tif" in the /Contents of the first annotation and a loop at Root/Pages/Kids/[0]/Annots/[0]/FS (always 14 0 R), while 3.0 doesn't have that, but doesn't have "BigTIFF.tif". I'm not sure which one (if any) is wrong.

> UPDATE
> 2.0.24 shows the same behaviour as 3.0
