Django 1.5.5 版本发行说明

October 23, 2013

Django 1.5.5 fixes a couple security-related bugs and several other bugs in the 1.5 series.

Readdressed denial-of-service via password hashers

Django 1.5.4 imposes a 4096-byte limit on passwords in order to mitigate a denial-of-service attack through submission of bogus but extremely large passwords. In Django 1.5.5, we’ve reverted this change and instead improved the speed of our PBKDF2 algorithm by not rehashing the key on every iteration.

Properly rotate CSRF token on login

This behavior introduced as a security hardening measure in Django 1.5.2 did not work properly and is now fixed.

漏洞修复

  • Fixed a data corruption bug with datetime_safe.datetime.combine (#21256).
  • Fixed a Python 3 incompatibility in django.utils.text.unescape_entities() (#21185).
  • Fixed a couple data corruption issues with QuerySet edge cases under Oracle and MySQL (#21203, #21126).
  • Fixed crashes when using combinations of annotate(), select_related(), and only() (#16436).

不向后兼容的变更

  • The undocumented django.core.servers.basehttp.WSGIServerException has been removed. Use socket.error provided by the standard library instead.
