pypdf: pypdf is an open source, pure-python PDF library
CVE-2023-36464 is fixed in 2 products on 1 platform, first by DEBIAN-CVE-2023-36464, released June 27, 2023. It is not reported as exploited. Patch Radar priority: Routine.
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"")`.
