python-cryptography-3.2.1-6.el8
影響のあるチャネル:
Asianux Server 8 for x86_64
Severity:
Moderate
Description:
以下項目について対処しました。
[Security Fix]
- python-cryptography の Cipher.update_into() 関数には、
イミュータブル属性の付与されたバッファーのみを返す問題が
あるため、リモートの攻撃者により、出力結果の破壊、および
サービス拒否攻撃 (クラッシュの発生) を可能とする脆弱性が
存在します。(CVE-2023-23931)
解決策:
パッケージをアップデートしてください。
CVE:
CVE-2023-23931
cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. In affected versions `Cipher.update_into` would accept Python objects which implement the buffer protocol, but provide only immutable buffers. This would allow immutable objects (such as `bytes`) to be mutated, thus violating fundamental rules of Python and resulting in corrupted output. This now correctly raises an exception. This issue has been present since `update_into` was originally introduced in cryptography 1.8.
