- Summary
- Manipulated inline images can cause Infinite Loop in PyPDF2
- Details

Impact
An attacker who uses this vulnerability can craft a PDF which leads to an infinite loop if the PyPDF2 user wrote the following code:
from PyPDF2 import PdfFileReader, PdfFileWriter from PyPDF2.pdf import ContentStream reader = PdfFileReader("malicious.pdf", strict=False) for page in reader.pages: ContentStream(page.getContents(), reader)Patches
PyPDF2==1.27.5and later are patched.Credits to Sebastian Krause for finding (issue) and fixing (PR) it.
