| CVE-2026-39892 | Cri | 0.57 | 9.8 | 0.01 | Apr 8, 2026 | cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. From 45.0.0 to before 46.0.7, if a non-contiguous buffer was passed to APIs which accepted Python buffers (e.g. Hash.update()), this could lead to buffer overflows. This… | ||
| CVE-2016-9243 | Hig | 0.42 | 7.5 | 0.03 | Mar 27, 2017 | HKDF in cryptography before 1.5.2 returns an empty byte-string if used with a length less than algorithm.digest_size. | ||
| CVE-2026-34073 | Med | 0.27 | 5.3 | 0.00 | Mar 31, 2026 | cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Prior to version 46.0.6, DNS name constraints were only validated against SANs within child certificates, and not the "peer name" presented during each validation.… | ||
| CVE-2026-26007 | 0.00 | — | 0.00 | Feb 10, 2026 | cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Prior to 46.0.5, the public_key_from_numbers (or EllipticCurvePublicNumbers.public_key()), EllipticCurvePublicNumbers.public_key(), load_der_public_key() and… | |||
| CVE-2024-26130 | 0.00 | — | 0.01 | Feb 21, 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… | |||
| CVE-2023-50782 | 0.00 | — | 0.01 | Feb 5, 2024 | A flaw was found in the python-cryptography package. This issue may allow a remote attacker to decrypt captured messages in TLS servers that use RSA key exchanges, which may lead to exposure of confidential or sensitive data. | |||
| CVE-2023-49083 | 0.00 | — | 0.01 | Nov 29, 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… | |||
| CVE-2022-40974 | 0.00 | — | 0.00 | May 10, 2023 | Incomplete cleanup in the Intel(R) IPP Cryptography software before version 2021.6 may allow a privileged user to potentially enable information disclosure via local access. | |||
| CVE-2022-41646 | 0.00 | — | 0.00 | May 10, 2023 | Insufficient control flow management in the Intel(R) IPP Cryptography software before version 2021.6 may allow an unauthenticated user to potentially enable information disclosure via local access. | |||
| CVE-2022-37409 | 0.00 | — | 0.00 | May 10, 2023 | Insufficient control flow management for the Intel(R) IPP Cryptography software before version 2021.6 may allow an authenticated user to potentially enable information disclosure via local access. | |||
| CVE-2023-23931 | 0.00 | — | 0.01 | Feb 7, 2023 | cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. In affected versions `Cipher.update_into` would accept Python objects which implement the buffer protocol, but provide only immutable buffers. This would allow immutable… |
