  • Security fix: Add a random timer to avoid timing oracles and simple bruteforce attacks when using the htpasswd authentication method.
  • Various minor fixes.

1.1.1 - Second Law of Nature

  • Fix the owner_write rights rule

1.1 - Law of Nature

One feature in this release is not backward compatible:

  • Use the first matching section for rights (inspired from daald)

Now, the first section matching the path and current user in your custom rights file is used. In the previous versions, the most permissive rights of all the matching sections were applied. This new behaviour gives a simple way to make specific rules at the top of the file independant from the generic ones.

Many improvements in this release are related to security, you should upgrade Radicale as soon as possible:

  • Improve the regex used for well-known URIs (by Unrud)
  • Prevent regex injection in rights management (by Unrud)
  • Prevent crafted HTTP request from calling arbitrary functions (by Unrud)
  • Improve URI sanitation and conversion to filesystem path (by Unrud)
  • Decouple the daemon from its parent environment (by Unrud)

Some bugs have been fixed and little enhancements have been added:

  • Assign new items to corret key (by Unrud)
  • Avoid race condition in PID file creation (by Unrud)
  • Improve the docker version (by cdpb)
  • Encode message and commiter for git commits
  • Test with Python 3.5
