Description:Summary:
Permissions enforced by iControl can lag behind the actual
permissions assigned to a user if the role_map is not reloaded between the time the permissions

in normal usage. The typical period in which this is possible is limited to at most a few seconds
after the permission change.

Vulnerability Impact:
When an iControl user has administrative privileges that are
later downgraded, the user will still be able to use their previous permissions using iControl
until the role map reloads.

Solution:
See the referenced vendor advisory for a solution.
