But he acknowledged that the Heartbleed incident had cast a light on a balancing test the White House has until now declined to discuss in any detail: When should the government reveal flaws that it discovers, and when should it use them for its still-unacknowledged “stockpile” of flaws that would help it penetrate foreign computer networks?
