[Security] Bump cryptography from 3.3.1 to 3.4.3 #40

Closed dependabot-preview[bot] closed 3 years ago

dependabot-preview[bot] commented 3 years ago

Bumps cryptography from 3.3.1 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  • Added additional debug output to assist users seeing installation errors due to outdated pip or missing rustc.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

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.
