| CVE-2024-26130 | 高危7.5 | 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_algorith | 21/02/2024 |
| CVE-2023-50782 | 高危7.5 | 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. | 05/02/2024 |
| CVE-2023-49083 | 高危7.5 | 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 | 29/11/2023 |
| CVE-2023-38325 | 高危7.5 | The cryptography package before 41.0.2 for Python mishandles SSH certificates that have critical options. | 14/07/2023 |
| CVE-2023-23931 | 中危6.5 | 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 objects (such as `bytes`) to be mutated, thus | 07/02/2023 |
| CVE-2020-36242 | 严重9.1 | In the cryptography package before 3.3.2 for Python, certain sequences of update calls to symmetrically encrypt multi-GB values could result in an integer overflow and buffer overflow, as demonstrated by the Fernet class. | 07/02/2021 |
| CVE-2020-25659 | 中危5.9 | python-cryptography 3.2 is vulnerable to Bleichenbacher timing attacks in the RSA decryption API, via timed processing of valid PKCS#1 v1.5 ciphertext. | 11/01/2021 |
| CVE-2016-9243 | 高危7.5 | HKDF in cryptography before 1.5.2 returns an empty byte-string if used with a length less than algorithm.digest_size. | 27/03/2017 |
