要点
- CVE-2024-26130 は cryptography, cryptography (cryptography.io) に影響する深刻度「高」 (CVSS 7.5) の脆弱性です。
- 今後30日間に悪用される確率（EPSS）：0.83%（全脆弱性の 57.6% より高い）。
- 対処：42.0.4 以降に更新してください。
概要
If pkcs12.serialize_key_and_certificates is called with both:
- A certificate whose public key did not match the provided private key
- An
encryption_algorithm with hmac_hash set (via PrivateFormat.PKCS12.encryption_builder().hmac_hash(...)
Then a NULL pointer dereference would occur, crashing the Python process.
This has been resolved, and now a ValueError is properly raised.

NVD の説明
cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Starting in version 38.0.0 and prior to version 42.0.4, if `pkcs12.serialize_key_and_certificates` is called with both a certificate whose public key did not match the provided private key and an `encryption_algorithm` with `hmac_hash` set (via `PrivateFormat.PKCS12.encryption_builder().hmac_hash(...)`, then a NULL pointer dereference would occur, crashing the Python process. This has been resolved in version 42.0.4, the first version in which a `ValueError` is properly raised.
