CVE-2023-36464
Good to know:
Date: June 27, 2023
pypdf is an open source, pure-python PDF library. In affected versions an attacker may craft a PDF which leads to an infinite loop if "__parse_content_stream" is executed. That is, for example, the case if the user extracted text from such a PDF. This issue was introduced in pull request #969 and resolved in pull request #1828. Users are advised to upgrade. Users unable to upgrade may modify the line "while peek not in (b"\r", b"\n")" in "pypdf/generic/_data_structures.py" to "while peek not in (b"\r", b"\n", b"")".
