An anonymous reader writes "The White House has joined the public debate about Heartbleed. The administration denied any prior knowledge of Heartbleed, and said the NSA should reveal such flaws once discovered. Unfortunately, this statement was hedged. The NSA should reveal these flaws unless 'a clear national security or law enforcement need' exists. Since that can be construed to apply to virtually any situation, we're left with the same dilemma as before: do we take them at their word or not? The use of such an exploit is certainly not without precedent: 'The NSA made use of four "zero day" vulnerabilities in its attack on Iran's nuclear enrichment sites. That operation, code-named "Olympic Games," managed to damage roughly 1,000 Iranian centrifuges, and by some accounts helped drive the country to the negotiating table.' A senior White House official is quoted saying, 'I can't imagine the president — any president — entirely giving up a technology that might enable him some day to take a covert action that could avoid a shooting war.'"
