# Django 3.2.11 リリースノート

*2022年1月4日*

Django 3.2.11 fixes one security issue with severity "medium" and two security
issues with severity "low" in 3.2.10.

## CVE-2021-45115: `UserAttributeSimilarityValidator` におけるサービス拒否攻撃 (DoS) の可能性

[`UserAttributeSimilarityValidator`](/ja/5.2/topics/auth/passwords/#django.contrib.auth.password_validation.UserAttributeSimilarityValidator) incurred significant overhead
evaluating submitted password that were artificially large in relative to the
comparison values. On the assumption that access to user registration was
unrestricted this provided a potential vector for a denial-of-service attack.

In order to mitigate this issue, relatively long values are now ignored by
`UserAttributeSimilarityValidator`.

This issue has severity "medium" according to the [Django security policy](/ja/5.2/internals/security/#severity-levels).

## CVE-2021-45116: `dictsort` テンプレートフィルタ内の潜在的な情報漏洩

Due to leveraging the Django Template Language's variable resolution logic, the
[`dictsort`](/ja/5.2/ref/templates/builtins/#std-templatefilter-dictsort) template filter was potentially vulnerable to information
disclosure or unintended method calls, if passed a suitably crafted key.

In order to avoid this possibility, `dictsort` now works with a restricted
resolution logic, that will not call methods, nor allow indexing on
dictionaries.

As a reminder, all untrusted user input should be validated before use.

This issue has severity "low" according to the [Django security policy](/ja/5.2/internals/security/#severity-levels).

## CVE-2021-45452: `Storage.save()` 経由の潜在的なディレクトリトラバーサル

適切に組み立てられたファイル名が直接渡された場合に、`Storage.save()` がディレクトリトラバーサルを許可してしまっていました。

This issue has severity "low" according to the [Django security policy](/ja/5.2/internals/security/#severity-levels).
