Django 3.2.11 release notes
|
|
===========================
|
|
|
|
*January 4, 2022*
|
|
|
|
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: Denial-of-service possibility in ``UserAttributeSimilarityValidator``
|
|
=====================================================================================
|
|
|
|
:class:`.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 :ref:`Django security policy
|
|
<security-disclosure>`.
|
|
|
|
CVE-2021-45116: Potential information disclosure in ``dictsort`` template filter
|
|
================================================================================
|
|
|
|
Due to leveraging the Django Template Language's variable resolution logic, the
|
|
:tfilter:`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 :ref:`Django security policy
|
|
<security-disclosure>`.
|
|
|
|
CVE-2021-45452: Potential directory-traversal via ``Storage.save()``
|
|
====================================================================
|
|
|
|
``Storage.save()`` allowed directory-traversal if directly passed suitably
|
|
crafted file names.
|
|
|
|
This issue has severity "low" according to the :ref:`Django security policy
|
|
<security-disclosure>`.
