chore(deps): [security] bump cryptography from 41.0.7 to 42.0.4

Bumps cryptography from 41.0.7 to 42.0.4. This update includes security fixes.

Vulnerabilities fixed

Python Cryptography package vulnerable to Bleichenbacher timing oracle attack 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.

Patched versions: 42.0.0 Affected versions: < 42.0.0

Null pointer dereference in PKCS12 parsing Issue summary: Processing a maliciously formatted PKCS12 file may lead OpenSSL to crash leading to a potential Denial of Service attack

Impact summary: Applications loading files in the PKCS12 format from untrusted sources might terminate abruptly.

A file in PKCS12 format can contain certificates and keys and may come from an untrusted source. The PKCS12 specification allows certain fields to be NULL, but OpenSSL does not correctly check for this case. This can lead to a NULL pointer dereference that results in OpenSSL crashing. If an application processes PKCS12 files from an untrusted source using the OpenSSL APIs then that application will be vulnerable to this issue.

OpenSSL APIs that are vulnerable to this are: PKCS12_parse(), PKCS12_unpack_p7data(), PKCS12_unpack_p7encdata(), PKCS12_unpack_authsafes() and PKCS12_newpass().

We have also fixed a similar issue in SMIME_write_PKCS7(). However since this function is related to writing data we do not consider it security significant.

Patched versions: 42.0.2 Affected versions: < 42.0.2

cryptography NULL pointer dereference with pkcs12.serialize_key_and_certificates when called with a non-matching certificate and private key and an hmac_hash override If pkcs12.serialize_key_and_certificates is called with both:

1. A certificate whose public key did not match the provided private key
2. 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.

Patched in pyca/cryptography#10423

Changelog

Sourced from cryptography's changelog.

42.0.4 - 2024-02-20

* Fixed a null-pointer-dereference and segfault that could occur when creating
  a PKCS#12 bundle. Credit to **Alexander-Programming** for reporting the
  issue. **CVE-2024-26130**
* Fixed ASN.1 encoding for PKCS7/SMIME signed messages. The fields ``SMIMECapabilities``
  and ``SignatureAlgorithmIdentifier`` should now be correctly encoded according to the
  definitions in :rfc:`2633` :rfc:`3370`.
.. _v42-0-3:
42.0.3 - 2024-02-15

• Fixed an initialization issue that caused key loading failures for some users.

.. _v42-0-2:

42.0.2 - 2024-01-30

* Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 3.2.1.
* Fixed an issue that prevented the use of Python buffer protocol objects in
  ``sign`` and ``verify`` methods on asymmetric keys.
* Fixed an issue with incorrect keyword-argument naming with ``EllipticCurvePrivateKey``
  :meth:`~cryptography.hazmat.primitives.asymmetric.ec.EllipticCurvePrivateKey.exchange`,
  ``X25519PrivateKey``
  :meth:`~cryptography.hazmat.primitives.asymmetric.x25519.X25519PrivateKey.exchange`,
  ``X448PrivateKey``
  :meth:`~cryptography.hazmat.primitives.asymmetric.x448.X448PrivateKey.exchange`,
  and ``DHPrivateKey``
  :meth:`~cryptography.hazmat.primitives.asymmetric.dh.DHPrivateKey.exchange`.
.. _v42-0-1:
42.0.1 - 2024-01-24

• Fixed an issue with incorrect keyword-argument naming with EllipticCurvePrivateKey :meth:~cryptography.hazmat.primitives.asymmetric.ec.EllipticCurvePrivateKey.sign.
• Resolved compatibility issue with loading certain RSA public keys in :func:~cryptography.hazmat.primitives.serialization.load_pem_public_key.

.. _v42-0-0:

42.0.0 - 2024-01-22
