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\".", "url": "https://t.me/cibsecurity/65818"}, {"timestamp": "2023-06-30T22:19:39Z", "date_only": false, "value": "2023-06-30T22:19:39Z", "kind": "milestone", "label": "Published", "source": "github", "record": "GHSA-HM9V-VJ3R-R55M", "field": "published"}, {"timestamp": "2023-06-30T22:19:39Z", "date_only": false, "value": "2023-06-30T22:19:39Z", "kind": "other", "label": "Updated", "source": "github", "record": "GHSA-HM9V-VJ3R-R55M", "field": "modified"}, {"timestamp": "2024-08-02T17:01:09.484Z", "date_only": false, "value": "2024-08-02T17:01:09.484Z", "kind": "other", "label": "Updated", "source": "cvelistv5 \u00b7 CVE-2023-36807 / CVE", "record": "CVE-2023-36807", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2024-11-06T19:51:03.876Z", "date_only": false, "value": "2024-11-06T19:51:03.876776Z", "kind": "other", "label": "Recorded", "source": "cvelistv5 \u00b7 CVE-2023-36807 / CISA-ADP", "record": "CVE-2023-36807", "field": "containers.adp.1.metrics.0.other.content.timestamp"}, {"timestamp": "2024-11-06T19:51:43.120Z", "date_only": false, "value": "2024-11-06T19:51:43.120Z", "kind": "other", "label": "Updated", "source": "cvelistv5 \u00b7 CVE-2023-36807", "record": "CVE-2023-36807", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2024-11-06T19:51:43.120Z", "date_only": false, "value": "2024-11-06T19:51:43.120Z", "kind": "other", "label": "Updated", "source": "cvelistv5 \u00b7 CVE-2023-36807 / CISA-ADP", "record": "CVE-2023-36807", "field": "containers.adp.1.providerMetadata.dateUpdated"}, {"timestamp": "2026-07-07T11:45:19.767Z", "date_only": false, "value": "2026-07-07T11:45:19.767457Z", "kind": "milestone", "label": "Published", "source": "pysec \u00b7 PYSEC-2026-1836", "record": "PYSEC-2026-1836", "field": "published"}, {"timestamp": "2026-07-07T11:45:19.767Z", "date_only": false, "value": "2026-07-07T11:45:19.767457Z", "kind": "other", "label": "Updated", "source": "pysec \u00b7 PYSEC-2026-1836", "record": "PYSEC-2026-1836", "field": "modified"}]}
