This pull request was created by Dependabot Preview, and you've upgraded to Dependabot. This means it won't respond to dependabot commands nor will it be automatically closed if a new version is found.

If you close this pull request, Dependabot will re-create it the next time it checks for updates and everything will work as expected.

Bumps cryptography from 3.2.1 to 3.4.3.

Changelog

Sourced from cryptography's changelog.

3.4.3 - 2021-02-08

  • Specify our supported Rust version (>=1.45.0) in our setup.py so users on older versions will get a clear error message.

3.4.2 - 2021-02-08

  • Improvements to make the rust transition a bit easier. This includes some better error messages and small dependency fixes. If you experience installation problems Be sure to update pip first, then check the FAQ </faq>.

3.4.1 - 2021-02-07

  • Fixed a circular import issue.
  • Added additional debug output to assist users seeing installation errors due to outdated pip or missing rustc.

3.4 - 2021-02-07

  • BACKWARDS INCOMPATIBLE: Support for Python 2 has been removed.
  • We now ship manylinux2014 wheels and no longer ship manylinux1 wheels. Users should upgrade to the latest pip to ensure this doesn't cause issues downloading wheels on their platform.
  • cryptography now incorporates Rust code. Users building cryptography themselves will need to have the Rust toolchain installed. Users who use an officially produced wheel will not need to make any changes. The minimum supported Rust version is 1.45.0.
  • cryptography now has 484 type hints on nearly all of of its public APIs. Users can begin using them to type check their code with mypy.

3.3.2 - 2021-02-07

  • SECURITY ISSUE: Fixed a bug where certain sequences of update() calls when symmetrically encrypting very large payloads (>2GB) could result in an integer overflow, leading to buffer overflows. CVE-2020-36242

3.3.1 - 2020-12-09

  • Re-added a legacy symbol causing problems for older pyOpenSSL users.

3.3 - 2020-12-08

  • BACKWARDS INCOMPATIBLE: Support for Python 3.5 has been removed due to low usage and maintenance burden.
  • BACKWARDS INCOMPATIBLE: The ~cryptography.hazmat.primitives.ciphers.modes.GCM and ~cryptography.hazmat.primitives.ciphers.aead.AESGCM now require 64-bit to 1024-bit (8 byte to 128 byte) initialization vectors. This change is to conform with an upcoming OpenSSL release that will no longer support sizes outside this window.
  • BACKWARDS INCOMPATIBLE: When deserializing asymmetric keys we now raise ValueError rather than UnsupportedAlgorithm when an unsupported cipher is used. This change is to conform with an upcoming OpenSSL release that will no longer distinguish between error types.
  • BACKWARDS INCOMPATIBLE: We no longer allow loading of finite field Diffie-Hellman parameters of less than 512 bits in length. This change is to conform with an upcoming OpenSSL release that no longer supports smaller sizes. These keys were already wildly insecure and should not have been used in any application outside of testing.
  • Updated Windows, macOS, and manylinux wheels to be compiled with OpenSSL 1.1.1i.
  • Python 2 support is deprecated in cryptography. This is the last release that will support Python 2.
  • Added the ~cryptography.hazmat.primitives.asymmetric.rsa.RSAPublicKey.recover_data_from_signature function to ~cryptography.hazmat.primitives.asymmetric.rsa.RSAPublicKey for recovering the signed data from an RSA signature.

We've just been alerted that this update fixes a security vulnerability:

Sourced from The GitHub Security Advisory Database.

Symmetrically encrypting large values can lead to integer overflow

Impact

When certain sequences of update() calls with large values (multiple GBs) for symetric encryption or decryption occur, it's possible for an integer overflow to happen, leading to mishandling of buffers.

Patches

This is patched in version 3.3.2 and newer.

Affected versions: [">= 3.1, < 3.3.2"]

dependabot-preview[bot] commented 3 years ago

A newer version of cryptography exists, but since this PR has been edited by someone other than Dependabot I haven't updated it. You'll get a PR for the updated version as normal once this PR is merged.

dependabot-preview[bot] commented 3 years ago

OK, I won't notify you again about this release, but will get in touch when a new version is available.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
