-----------------------------------
Summary: Infinite loop on corrupted PDF in 3.0.0-SNAPSHOT
Key: PDFBOX-5158
URL: https://issues.apache.org/jira/browse/PDFBOX-5158
Project: PDFBox
Issue Type: Task
Reporter: Tim Allison
I found a bunch of files that had a "read too many EOFs", which is a safety
check we now do in TikaInputStream to identify parsers that read an EOF > 1000
times, which may be a sign of an infinite loop.
When I turn off this safety check in TikaInputStream, I get an infinite loop.
This is one of the triggering files:
https://corpora.tika.apache.org/base/docs/commoncrawl3/OE/OELHPKYAQPDNDWC535NE23Z6FKYRMN7W
It's a truncated file from Common Crawl.
The stacktrace when this is thrown is:
