6.2.3

=========================

Bug Fixes
---------

- `8414 <https://github.com/pytest-dev/pytest/issues/8414>`_: pytest used to create directories under ``/tmp`` with world-readable
permissions. This means that any user in the system was able to read
information written by tests in temporary directories (such as those created by
the ``tmp_path``/``tmpdir`` fixture). Now the directories are created with
private permissions.

pytest used to silenty use a pre-existing ``/tmp/pytest-of-<username>`` directory,
even if owned by another user. This means another user could pre-create such a
directory and gain control of another user's temporary directory. Now such a
condition results in an error.
