dependabot-preview[bot] commented 3 years ago

Bumps cryptography from 3.0 to 3.2. This update includes a security fix.

Vulnerabilities fixed

Sourced from The GitHub Security Advisory Database.

RSA decryption vulnerable to Bleichenbacher timing vulnerability

Impact

RSA decryption was vulnerable to Bleichenbacher timing vulnerabilities, which would impact people using RSA decryption in online scenarios.

Patches

This is fixed in cryptography 3.2. https://github.com/pyca/cryptography/commit/58494b41d6ecb0f56b7c5f05d5f5e3ca0320d494 is the resolving commit.

Affected versions: < 3.2

Changelog

Sourced from cryptography's changelog.

3.2 - 2020-10-25

  • SECURITY ISSUE: Attempted to make RSA PKCS#1v1.5 decryption more constant time, to protect against Bleichenbacher vulnerabilities. Due to limitations imposed by our API, we cannot completely mitigate this vulnerability and a future release will contain a new API which is designed to be resilient to these for contexts where it is required. Credit to Hubert Kario for reporting the issue. CVE-2020-25659
  • Support for OpenSSL 1.0.2 has been removed. Users on older version of OpenSSL will need to upgrade.
  • Added basic support for PKCS7 signing (including SMIME) via ~cryptography.hazmat.primitives.serialization.pkcs7.PKCS7SignatureBuilder.

3.1.1 - 2020-09-22

  • Updated Windows, macOS, and manylinux wheels to be compiled with OpenSSL 1.1.1h.

3.1 - 2020-08-26

  • BACKWARDS INCOMPATIBLE: Removed support for idna based U-label parsing in various X.509 classes. This support was originally deprecated in version 2.1 and moved to an extra in 2.5.
  • Deprecated OpenSSL 1.0.2 support. OpenSSL 1.0.2 is no longer supported by the OpenSSL project. The next version of cryptography will drop support for it.
  • Deprecated support for Python 3.5. This version sees very little use and will be removed in the next release.
  • backend arguments to functions are no longer required and the default backend will automatically be selected if no backend is provided.
  • Added initial support for parsing certificates from PKCS7 files with ~cryptography.hazmat.primitives.serialization.pkcs7.load_pem_pkcs7_certificates and ~cryptography.hazmat.primitives.serialization.pkcs7.load_der_pkcs7_certificates .
  • Calling update or update_into on ~cryptography.hazmat.primitives.ciphers.CipherContext with data longer than 2^31^ bytes no longer raises an OverflowError. This also resolves the same issue in /fernet.

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version.

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