I have attached an invalid pdf file.
when I wanted to open that pdf file,
I have faced with long time to read a pdf (more than 1 hour).
seems a bug is in PdfFileReader.
this is my test to reproduce the bug on PyPDF2==1.26.0 and python 3.6:

MCVE: Code + PDF

Example PDF: file1.pdf

from PyPDF2 import PdfReader

p = PdfFileReader("file1.pdf") # in this line we will be wait a long
