             Summary: Non-large PDF's can cause Out of Memory Exceptions
                 Key: PDFBOX-3856
                 URL: https://issues.apache.org/jira/browse/PDFBOX-3856
             Project: PDFBox
          Issue Type: Bug
            Reporter: Nicholas DiPiazza
            Priority: Blocker
         Attachments: Pasted image at 2017_07_05 02_26 PM.png

We are using an application that attempts to make PDFs searchable using Apache Tika which
in downstream uses PDF Box to parse PDFs to extract the body of a PDF in text to make it searchable.


We allow basically any PDF from anywhere to come in as long as it isn't too large (9 MB).

However, we are noticing some PDFs, even though they are not that large in file size, can
cause zip bombs to eat up all the heap space and crash the JVM.

There is some sort of Object[] array that has millions of {{{org.apache.pdfbox.text.TextPosition}}}.

Is there a setting to limit the size of this particular array so that it doesn't cause a memory
bomb?
