There are those secret bugs, that are not visible for public. But you can still get information about them!! This is because when the state of such a bug changes and you are listening to a public bug that has the secret bug as dependency, then you get an email saying "secret-bug #?: 'summary of some real bad security hole in Mozilla'" state changed ... Actual Result: So everybody listening to the public bug knows about the secret one and normaly the summary is just enough for hackers to exploit that bug. Expected Result: No summary of secret bugs should be given on state-change-notifications.
