`OSSA-2019-003`_: Nova Server Resource Faults Leak External Exception
Details (CVE-2019-14433)
This release contains a security fix for `bug 1837877`_ where users
without the admin role can be exposed to sensitive error details in
the server resource fault ``message``.
There is a behavior change where non-nova exceptions will only record
the exception class name in the fault ``message`` field which is exposed
to all users, regardless of the admin role.
The fault ``details``, which are only exposed to users with the admin role,
will continue to include the traceback and also include the exception
value which for non-nova exceptions is what used to be exposed in the
fault ``message`` field. Meaning, the information that admins could see
for server faults is still available, but the exception value may be in
``details`` rather than ``message`` now.
