CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 0CVE-2024-26130 – cryptography NULL pointer deference with pkcs12.serialize_key_and_certificates when called with a non-matching certificate and private key and an hmac_hash override
https://notcve.org/view.php?id=CVE-2024-26130
21 Feb 2024 — 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 ver... • https://github.com/pyca/cryptography/commit/97d231672763cdb5959a3b191e692a362f1b9e55 • CWE-476: NULL Pointer Dereference •
CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 1CVE-2023-49083 – cryptography vulnerable to NULL-dereference when loading PKCS7 certificates
https://notcve.org/view.php?id=CVE-2023-49083
29 Nov 2023 — cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Calling `load_pem_pkcs7_certificates` or `load_der_pkcs7_certificates` could lead to a NULL-pointer dereference and segfault. Exploitation of this vulnerability poses a serious risk of Denial of Service (DoS) for any application attempting to deserialize a PKCS7 blob/certificate. The consequences extend to potential disruptions in system availability and stability. This vulnerability has been patched in v... • https://github.com/pyca/cryptography/commit/f09c261ca10a31fe41b1262306db7f8f1da0e48a • CWE-476: NULL Pointer Dereference •
