CVE-2020-25659 2 Cryptography.io, Oracle 2 Cryptography, Communications Cloud Native Core Network Function Cloud Native Environment 2024-09-09 4.3 MEDIUM 5.9 MEDIUM
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.
CVE-2016-9243 3 Canonical, Cryptography.io, Fedoraproject 3 Ubuntu Linux, Cryptography, Fedora 2024-09-09 5.0 MEDIUM 7.5 HIGH
HKDF in cryptography before 1.5.2 returns an empty byte-string if used with a length less than algorithm.digest_size.
CVE-2023-50782 3 Couchbase, Cryptography.io, Redhat 5 Couchbase Server, Cryptography, Ansible Automation Platform and 2 more 2024-09-05 N/A 7.5 HIGH
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-2023-23931 1 Cryptography.io 1 Cryptography 2024-09-05 N/A 6.5 MEDIUM
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 violating fundamental rules of Python and resulting in corrupted output. This now correctly raises an exception. This issue has been present since `update_into` was originally introduced in cryptography 1.8.
CVE-2023-38325 1 Cryptography.io 1 Cryptography 2024-09-05 N/A 7.5 HIGH
The cryptography package before 41.0.2 for Python mishandles SSH certificates that have critical options.
CVE-2020-36242 3 Cryptography.io, Fedoraproject, Oracle 3 Cryptography, Fedora, Communications Cloud Native Core Network Function Cloud Native Environment 2024-09-05 6.4 MEDIUM 9.1 CRITICAL
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.
CVE-2023-49083 1 Cryptography.io 1 Cryptography 2024-09-05 N/A 7.5 HIGH
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 version 41.0.6.
