16.0.2
^^^^^^


Security Issues
***************

* [bug 1901207 (https://bugs.launchpad.net/keystone/+bug/1901207)]
  Policy enforcement for application credentials has been updated to
  protect against invalid ownership checks resulting in unauthorized
  users being able to get and delete application credentials for other
  users.


Bug Fixes
*********

* [bug 1688137 (https://bugs.launchpad.net/keystone/+bug/1688137)]
  Fixed the AccountLocked exception being shown to the end user since
  it provides some information that could be exploited by a malicious
  user. The end user will now see Unauthorized instead of
  AccountLocked, preventing user info oracle exploitation.

* [bug 1878938 (https://bugs.launchpad.net/keystone/+bug/1878938)]
  Previously when a user used to have system role assignment and tries
  to delete the same role, the system role assignments still existed
  in system_assignment table. This causes keystone to return *HTTP 404
  Not Found* errors when listing role assignments with names (e.g.,
  *--names* or *?include_names*).

  If you are affected by this bug, you must remove stale role
  assignments manually. The following is an example SQL statement you
  can use to fix the issue, but you should verify it's applicability
  to your deployment's SQL implementation and version.

  SQL:
     * delete from system_assignment where role_id not in (select id
       from role);

* [bug 1885753 (https://bugs.launchpad.net/keystone/+bug/1885753)]
  Keystone's SQL identity backend now retries update user requests to
  safely handle stale data when two clients update a user at the same
  time.

* [bug 1889936 (https://bugs.launchpad.net/keystone/+bug/1889936)]
  Properly decode octet strings, or byte arrays, returned from LDAP.

* [bug 1896125 (https://bugs.launchpad.net/keystone/+bug/1896125)]
  Introduced more robust connection handling for asynchronous LDAP
  requests to address memory leaks fetching data from LDAP backends
  with low page sizes.

* [bug 1901654 (https://bugs.launchpad.net/keystone/+bug/1901654)]
  Previously, generate_public_ID() in sha256.py assumed the passed
  arguments is str data type. However, python-ldap 3.0 or later
  returns bytes data type for attribute values except fields of
  distinguished names, relative distinguished names, attribute names,
  queries. If keystone running on Python3 is integrated with LDAP and
  the LDAP server has local_id variable in its attribute, user login
  operations will fail due to the assumption and modifiation of
  python-ldap. By this fix, generate_public_ID() properly handles
  bytes data type in the parameter.
