When I try to read the metadata of Effective Java 3rd Edition by Joshua Bloch.pdf it takes extremely long. It might even be an infinite loop.
Environment
Which environment were you using when you encountered the problem?
$ python -m platform
Linux-5.4.0-125-generic-x86_64-with-debian-bullseye-sid
$ python -c "import PyPDF2;print(PyPDF2.__version__)"
2.10.5
Code + PDF
This is a minimal, complete example that shows the issue:
from PyPDF2 import PdfReader
reader = PdfReader("Effective Java 3rd Edition by Joshua Bloch.pdf")
metadata = reader.metadataThe PDF: Effective Java 3rd Edition by Joshua Bloch.pdf
