- Update to 4.2.6 (bsc#1215978, CVE-2023-43665)
* CVE-2023-43665: Denial-of-service possibility in
django.utils.text.Truncator
The input processed by Truncator, when operating in HTML mode, has
been limited to the first five million characters in order to
avoid potential performance and memory issues.
* Fixed a regression in Django 4.2.5 where overriding the deprecated
DEFAULT_FILE_STORAGE and STATICFILES_STORAGE settings in tests
caused the main STORAGES to mutate (#34821).
* Fixed a regression in Django 4.2 that caused unnecessary casting
of string based fields (CharField, EmailField, TextField,
CICharField, CIEmailField, and CITextField) used with the __isnull
lookup on PostgreSQL. As a consequence, indexes using an __isnull
expression or condition created before Django 4.2 wouldn’t be used
by the query planner, leading to a performance regression
(#34840).
