An authenticated WebLogic Portal administrator or Delegated administrator can cause an inadvertent corruption of a visitor entitlements role when editing the role description if more than 255 characters are entered. This will cause any resources that were protected to no longer be protected. This vulnerability can occur by either editing a role description via the WebLogic Portal Administration Console or thru a portal application using the WebLogic Portal APIs.
A fix has been provided which prevents the entry of more than 255 characters.
