chore(deps): [security] bump cryptography from 41.0.7 to 42.0.2

HIFIS Bot requested to merge dependabot-pip-cryptography-42.0.2 into main

Bumps cryptography from 41.0.7 to 42.0.2. 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.

Changelog

Sourced from cryptography's changelog.

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


* **BACKWARDS INCOMPATIBLE:** Dropped support for LibreSSL < 3.7.
* **BACKWARDS INCOMPATIBLE:** Loading a PKCS7 with no content field using
  :func:`~cryptography.hazmat.primitives.serialization.pkcs7.load_pem_pkcs7_certificates`
  or
  :func:`~cryptography.hazmat.primitives.serialization.pkcs7.load_der_pkcs7_certificates`
  will now raise a ``ValueError`` rather than return an empty list.
* Parsing SSH certificates no longer permits malformed critical options with
  values, as documented in the 41.0.2 release notes.
* Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 3.2.0.
* Updated the minimum supported Rust version (MSRV) to 1.63.0, from 1.56.0.
* We now publish both ``py37`` and ``py39`` ``abi3`` wheels. This should
  resolve some errors relating to initializing a module multiple times per
  process.
* Support :class:`~cryptography.hazmat.primitives.asymmetric.padding.PSS` for
  X.509 certificate signing requests and certificate revocation lists with the
  keyword-only argument ``rsa_padding`` on the ``sign`` methods for
  :class:`~cryptography.x509.CertificateSigningRequestBuilder` and
  :class:`~cryptography.x509.CertificateRevocationListBuilder`.
* Added support for obtaining X.509 certificate signing request signature
  algorithm parameters (including PSS) via
