In version 2.10.5 an attacker who uses this vulnerability can craft a PDF which leads to an infinite loop. This infinite loop blocks the current process and can utilize a single core of the CPU by 100%. It does not affect memory usage. That is, for example, the case if the user extracted metadata from such a malformed PDF. Versions prior to 2.10.5 throw an error, but do not hang forever. This issue was fixed with https://github.com/py-pdf/pypdf/pull/1331 which has been included in release 2.10.6. Users are advised to upgrade. Users unable to upgrade should modify `PyPDF2/generic/_data_structures.py::read_object` to an an error throwing case. See GHSA-hm9v-vj3r-r55m for details.\n\n\ud83d\udcd6 Read\n\nvia \"National Vulnerability Database\".", "creation_timestamp": "2023-06-30T22:15:17.000000Z"} {"uuid": "ed5ca7d3-0570-459a-b5bb-9f23763a7d6d", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "2a075640-a300-48a4-bb44-bc6130783b9b", "vulnerability": "GHSA-HM9V-VJ3R-R55M", "type": "published-proof-of-concept", "source": "https://t.me/cibsecurity/65818", "content": "\u203c CVE-2023-36807 \u203c\n\npypdf is a pure-python PDF library capable of splitting, merging, cropping, and transforming the pages of PDF files.
