The White House recently issued a directive requiring all government agencies to urgently apply new patches to Microsoft Corp Exchange email servers to prevent exploitation by hackers. Anne Neuberger, deputy national security adviser for Cyber & Emerging Technologies, says, “We recognize when vulnerabilities may pose such a systemic risk that they require expedited disclosure.”

While the guidelines apply to software fixes for four vulnerabilities discovered by the US National Security Agency, Microsoft revealed that it had not seen the problems exploited so far, but said that hackers will study the new patches to see what they fix and then use attacks against unpatched machines.
