[jira] [Updated] (PDFBOX-3856) Non-large PDF's can cause Out of
Memory Exceptions
[ https://issues.apache.org/jira/browse/PDFBOX-3856?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Nicholas DiPiazza updated PDFBOX-3856:
--------------------------------------
Description:
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 {code}org.apache.pdfbox.text.TextPosition{code}
Is there a setting to limit the size of this particular array so that it doesn't cause a memory bomb?
