+This patch addresses CVE-2014-6414 and is tracked under Launchpad bug
+1357379. It is addressed in the Juno trunk and Icehouse 2014.1.3. There
+is no patch for Havana since it is EOL'ed by upstream. Therefore, this
+patch is derived from the patch for Icehouse 2014.1.3

+
+ Forbid regular users to reset admin-only attrs to default values
+
+ A regular user can reset an admin-only attribute to its default
+ value due to the fact that a corresponding policy rule is
+ enforced only in the case when an attribute is present in the
+ target AND has a non-default value.
+
+ Added a new attribute "attributes_to_update" which contains a list
+ of all to-be updated attributes to the body of the target that is
+ passed to policy.enforce.
+
+ Changed a check for whether an attribute is explicitly set.
+ Now, in the case of update, the function should not pay attention
+ to a default value of an attribute, but check whether it was
+ explicitly marked as being updated.
+
+ Added unit-tests.
